Sunshine Coast River And Island Guide

Maroochy River And Mudjimba Island Guide: Paddle, Snorkel And Walk

Most people come to Marcoola for the surf beach, but just south of it the coast turns into something quite different: a wide, calm tidal river, mangrove wetlands, a riverside conservation park and a small rocky island offshore with coral on its western side. This guide covers the water and wild country within about 15 minutes of Marcoola, from snorkelling Mudjimba Island and taking a 16-seat barbecue pontoon up the Maroochy River to paddling council canoe trails and walking the wetlands boardwalk.

Key Takeaway

Marcoola sits at the northern end of a river-and-island landscape that most beach visitors never explore. Within a short drive you can snorkel coral off Mudjimba Island on a guided boat trip, walk the riverside forest of the Maroochy River Conservation Park, hire a pontoon big enough for 16, paddle mapped canoe trails and stroll a pram-friendly wetland boardwalk. Plan each around the tide, the wind and the mosquitoes.

Three Distances To Know

Approximate drives from central Marcoola, mapped in late September 2026. Holiday traffic adds time.

1 Mudjimba Esplanade: about 4km, roughly six minutes, for the island view and the conservation park walk.
2 Bradman Avenue, Maroochydore: about 10km, roughly twelve minutes, for boat, kayak and paddleboard hire.
3 Maroochy Wetlands Sanctuary: about 12km, roughly fifteen minutes, via Sports Road at Bli Bli.

Three Checks Before You Get On The Water

The river rewards a little planning.

1 Tide and wind: paddle with the tide where you can and avoid strong northerly or southerly winds.
2 Mosquitoes: the wetlands and riverside forest are mosquito country, so pack repellent and long sleeves.
3 Rules: check fishing limits, dog areas and patrol times before you go, as all of them change.

Why Marcoola Makes A Good Base For River And Island Days

Marcoola is a quiet beachside suburb on the open ocean coast of the Sunshine Coast, with Yaroomba and Mount Coolum to the north and Mudjimba to the south. Drive a few minutes south and the coast changes character. Mudjimba looks straight out at Mudjimba Island, also called Old Woman Island. Past Mudjimba is Twin Waters, bounded by the Maroochy River to the south, and the river then winds inland past Bli Bli and its wetlands and out to sea between Twin Waters and Cotton Tree.

That gives a Marcoola stay two very different kinds of water within a quarter of an hour. The ocean beach is long, open and exposed, with surf, rips and wind. The river is sheltered and tidal, lined with mangroves and paperbarks, full of birds and much friendlier for paddling, fishing and floating about on a hired boat.

Most of this guide sits within a ten-to-fifteen-minute drive. The one exception is the Mudjimba Island snorkel boats, which leave from The Wharf at Mooloolaba, roughly 19km away, so allow 20 to 25 minutes for that trip.

The ocean beach is the headline, but the river is where Marcoola visitors go when they want calm water, birds and a slower pace.

The Story Written Into This Landscape

Before you look at Mudjimba Island from the beach, it helps to know the story that ties it to the mountain behind you and the river to the south. Sunshine Coast Council's heritage library retells the Dreamtime legend of Maroochy.

In the version it records, a young woman named Maroochy was loved by Coolum, a young warrior. Another warrior, Ninderry, abducted her, and Coolum rescued her while Ninderry slept. Ninderry gave chase and threw a nulla (club) at Coolum, knocking off his head, which rolled into the sea and became Mudjimba Island. Coolum's body became Mount Coolum. The spirit Birral turned Ninderry to stone, now Ninderry Crest, and Maroochy fled to the Blackall Range, where her tears formed the Maroochy River. She became a black swan and, the story says, still travels the river searching for Coolum's spirit.

Stand on Mudjimba beach and you can see the whole story at once: the island offshore, Mount Coolum's dome to the north and the river mouth to the south. Tell the children before the trip and an island view becomes something they remember.

Mudjimba Island: What It Is And Why You Cannot Just Paddle Out

Mudjimba Island is small. ABC News described it as just under five acres, sitting less than 2km off the mainland, and reported that it is a conservation park. Its modern history includes a residential lease granted in 1968 and later surrendered to the state in 1993.

What matters for visitors is how hard the island is to reach. ABC's reporting describes rocky outcrops, strong ocean currents and no defined landing point for vessels, and says few people have set foot on it. Surfers, divers and people fishing use the water around it, but that is open ocean, not a sheltered bay.

Paddling a hire kayak or stand-up board across from the beach is a very different proposition from paddling the river. It means crossing open water with swell, currents and boat traffic, and it is not something to try on a whim with a family group.

The island is a view from the beach and a trip by boat For most visitors the safe way to enjoy Mudjimba Island is from the sand at Mudjimba or on a guided snorkel boat.

Snorkelling Mudjimba Island With A Guided Boat Trip

The best reason to get out to the island is under the water. Visit Sunshine Coast describes coral gardens starting at just two metres deep, with hard and soft coral, gullies, ledges and bommies, and turtles resting in the shallows. Its snorkel guide adds dolphins, stingrays, crayfish, wobbegongs and eels, and puts the reef on the western side at 3 to 5 metres.

Three operators published Mudjimba Island snorkel trips from Mooloolaba when we checked in late September 2026:

Sunreef Mooloolaba

From The Wharf Mooloolaba. A four-hour trip from $99 with mask, snorkel, fins, wetsuit and an in-water guide included. No children under eight.

The Pressure Project

Also from The Wharf. A two-hour trip at $120 with gear, guide, GoPro footage, snacks and a towel, maximum eight guests, minimum age ten. Morning trips typically 7am.

Scuba World

From 207 Brisbane Road, Mooloolaba. About two and a half hours at $99 with gear hire extra. Minimum age nine; runs in school holidays and on demand, minimum eight people.

All three are open-water trips where conditions decide the day. The Pressure Project refunds only when it cancels for weather and says sightings are never guaranteed, and Sunreef suggests considering seasickness medication. Scuba World highly recommends wetsuits from July to September, so early spring water can still feel cool.

For a large group, check the age limits before promising the trip to everyone. Families with children under eight or ten will need to split the day, which is where the river options below come in.

Prices and times as found Prices, inclusions, ages and times were published by each operator in late September 2026. Confirm directly when you book.

Walk The Maroochy River Conservation Park From Mudjimba

Between Mudjimba and the river sits the Maroochy River Conservation Park, protected forest and wetland that most visitors drive straight past. It was established in 1992 and covers 174 hectares managed mainly for nature conservation.

Sunshine Coast Council's Adventure Sunshine Coast site lists the walk as easy, about 3.1km one way and suitable for all ages. You can start from the side of Ocean Road opposite the Novotel Twin Waters Resort, where parking is limited, or from Mudjimba Beach Esplanade via Cottonwood Street. The track passes through eucalypt forest full of birdlife and crosses swampy sections on timber boardwalks.

For a loop, the Sunshine Coast Walks site describes a 5.9km easy circuit from Mudjimba Esplanade via Cottonwood Street, the river trail and Ocean Drive, returning the same way through a second forest entrance.

Both sources give the same warnings: sections can become very boggy or impassable after decent rain, there may be fallen timber, parts are narrow, and mosquitoes are a given. After a wet week, save this walk for later.

Finishing at Mudjimba works well for groups. The council notes shops, a playground, refreshments and toilets on Mudjimba Esplanade, about 30 metres from the track exit. It lists Mudjimba Beach as accesses 117 to 131, with the surf club beside Power Memorial Park at access 123 and lifeguard services year round, so walkers who want a swim should have it there, between the flags.

Take A 16-Seat Barbecue Pontoon Up The Maroochy

For a big group, the most memorable river day is usually a hired pontoon. Swan Boat Hire, at 71 Bradman Avenue in Maroochydore, has been on the river for more than 29 years according to its website, which says no licence is needed for its rental boats and a safety briefing is included.

Its largest boat, the Maroochy DreamBoat, takes up to 16 people, which matches a full house. In late September 2026 the published prices were $509 for two hours, $583 for three, $636 for four, $731 for six and $774 for seven, with fuel and gas included. It has a full roof with roll-down blinds, a three-burner barbecue, a pizza oven, a large dining table, an enclosed toilet and a rear deck with a drop-down ladder, and Swan Boat Hire says it is wheelchair, walker and pram accessible. Smaller groups can choose 12-seat barbecue boats from $424 or five-seat polycraft boats from $175.

Treat a pontoon day as a slow circuit: cook lunch on board, drop a line off the back deck and be back before your hire time ends. Ask the staff which parts of the river to avoid. The river mouth, where tidal flow, sandbanks and ocean swell meet, is no place for a hired barbecue boat.

Book the pontoon early for weekends Large boats are limited, and spring weekends fill first. Prices were published by Swan Boat Hire in late September 2026; confirm when you book.

Kayaks, Canoes And Paddleboards On Calm Water

Paddling is the quieter way to meet the river. Kayaks, canoes and stand-up paddleboards can be hired on Bradman Avenue, and the lower Maroochy is usually sheltered compared with the beach at Marcoola, which makes it the natural choice when the surf is too big.

Visit Sunshine Coast singles out Cotton Tree, on the southern side of the river mouth, as a favourite paddleboarding spot. It suggests parking at the Cotton Tree swimming pool and launching in front of the caravan park, and notes that only advanced paddlers should try the waves at the river mouth. Cotton Tree is about 15km by road from Marcoola, around 20 minutes.

Use the tide

Head out against a weak tide and come home with it, so the tired leg is the easy one.

Watch the wind

Council canoe trail notes advise avoiding windy days, especially winds blowing due north or south.

Tell someone

Share your route and return time, wear a life jacket and carry a phone in a dry bag. In an emergency call 000.

Two Council Canoe Trails Worth Knowing

Sunshine Coast Council maps several Maroochy River canoe trails on its Adventure Sunshine Coast site. Two suit Marcoola visitors particularly well.

Muller Park Paddle, Bli Bli (intermediate)

This trail starts at Muller Park, via Muller Park Road off David Low Way, about eleven minutes' drive from Marcoola. The council rates it intermediate, 5.2km one way, with an 8km return option paddling north. The banks are thick with paperbarks and mangroves, and you may see some of the more than 200 bird species recorded in the area, plus mud crabs and fiddler crabs. Landmarks include the Maroochy Wetlands Sanctuary and glimpses of Bli Bli Castle.

Muller Park suits the non-paddlers too. The council lists a boat ramp, toilets, picnic shelters, barbecues, a shaded Indigenous-themed playground, a skate park and a fenced dog park, and the Bli Bli Aqua Park sits beside it; check its sessions and age rules online.

Dunethin Lake Paddle (easy)

For beginners and young children, this is a 1.8km circuit around Dunethin Lake, via Lake Dunethin Road off Peace Road from the Yandina-Bli Bli Road, about 23 minutes' drive away. The council calls it generally the most peaceful paddle, rarely affected by wind, low water or tides. There are picnic tables and toilets but no drinking water, parking is limited, and the council notes that Lake Dunethin Scouts nearby offers low-cost canoe hire. Spoonbills, ospreys and sea eagles are regular sightings.

Maroochy Wetlands Sanctuary: A Boardwalk Through The Mangroves

If you only have an hour, this is the easiest way to see the river's wild side. The sanctuary is on Sports Road at Bli Bli, about fifteen minutes from Marcoola. Sunshine Coast Council describes a 900-metre (one way) boardwalk that winds to the Maroochy River. It is two metres wide, step-free, suitable for prams and wheelchairs, and has seating and an interactive audio trail.

A reserve information sheet from the Sunshine Coast Environmental Education Centres adds a 220-metre bird hide loop, a crab platform loop and a pontoon on the river. It says the sanctuary is open every day and that volunteers staff the information centre each Sunday, and notes that Sports Road access was unsealed.

The council says more than 200 bird species have been recorded here, along with crabs, butterflies and reptiles, and that the sanctuary is home to the endangered water mouse. Children can often spot fiddler and semaphore crabs from the crab platform at low tide.

Timing matters. The information sheet names May to October as the best months because the sanctuary is mosquito habitat. Late September and October are still inside that window; from November, go early, cover up and use plenty of repellent.

Go in October, go in the morning and take the repellent: the wetlands are at their best before the summer mosquitoes arrive.

Birds On The River Mouth And Sandbanks

The lower Maroochy is one of the better places on the Sunshine Coast to see shorebirds. The Queensland Wader Study Group lists the Maroochydore river mouth as a wader site, with birds gathering at low tide near Goat Island and on the sandbanks in the river's south channel.

Species it lists as common include the bar-tailed godwit, whimbrel, eastern curlew, red-necked stint, pied oystercatcher and red-capped plover, and it notes that red-capped plovers breed locally between September and December.

The group suggests watching from near the swimming pool on the Esplanade at Cotton Tree or from Picnic Point Esplanade a little further north. It says weekends bring more disturbance, so weekdays at low tide are best. Watch from a distance, keep children from chasing flocks and keep dogs well away.

Fishing And Crabbing The Maroochy: Limits To Know

The Maroochy is a classic south-east Queensland estuary, and a pontoon or small hire boat with a few rods keeps a mixed group busy for a morning. Queensland's tidal limits apply to everything you keep. In late September 2026 the Queensland Government's size and possession limits page listed:

Dusky flathead

Minimum 40cm, maximum 75cm, limit of five.

Yellowfin bream

Minimum 25cm, combined limit of 30 with pikey bream and tarwhine.

Sand whiting

Minimum 23cm, combined limit of 30 with goldenline and northern whiting.

Mud crabs

Males only, minimum 15cm, seven per person or 14 per boat with two or more aboard. Females are no take.

Crab pot and dilly rules and closed seasons are set out separately by the Queensland Government, so read the current rules before setting gear, and pack a measuring ruler. Catch and release is a perfectly good plan: dinner back at the house does not have to depend on the fish.

Swimming In The River: Know Where And When It Is Patrolled

Calm-looking river water is not the same as safe water. Tidal flow can be strong, channels drop away beside sandbanks, and boats and jet skis use the river too.

Sunshine Coast Council lists the Maroochy River mouth (accesses 140 to 143) as patrolled only during the Queensland school holidays in September, at Christmas and at Easter, from 7.30am to 5pm. Once the spring holidays end in early October, treat it as unpatrolled until Christmas and do not swim there.

For a proper swim, go to a patrolled ocean beach such as Mudjimba and stay between the red and yellow flags. On the river, keep any splashing to very shallow, slow water, stay within arm's reach of young children and wear life jackets on boats and boards. Check the council's patrolled beaches page before you go.

Bringing The Dog To The River

Swan Boat Hire describes its boats as pet friendly, so a dog can join a pontoon day if you mention it when booking, and Muller Park has a fenced dog park for while others paddle. Beaches and reserves are different: Sunshine Coast Council's new dog rules took effect on 3 July 2026, and Sunshine Coast News reported restrictions on some sections of Mudjimba beach and seasonal limits at Twin Waters to protect migratory shorebirds. Check the council's dog access map and signs before letting a dog off the lead, and leave the wetlands and shorebird areas to the humans.

Why Aaron's Beachside Boat House Suits A River And Island Stay

River and island days are active, salty and often split between different parts of a group. Aaron's Beachside Boat House in Marcoola fits that kind of holiday because of how its space is laid out, not just its size.

The listing shows six bedrooms for up to 16 guests, the same number as the river's largest barbecue pontoon, so everyone can travel together for the big day out.

It also has two self-contained living zones, each with its own kitchen. The early snorkel crew can have breakfast downstairs at 6am without waking the families saving themselves for a slow wetlands walk. Outdoor dining for 10 upstairs and 20 downstairs means the whole group can sit down together in the evening.

Back home, a private saltwater pool sits in a fully fenced, landscaped tropical backyard with a barbecue area: a good place to cook the day's catch while children too young for the island boat trip have their own swim. A sheltered deck with hammock seating suits anyone resting after a paddle, Yaroomba Beach is a three-minute walk for sunrise, and Wi-Fi of more than 500 Mbps makes checking tides and bookings easy.

How A Group Of 16 Splits A River Day

With a big group on the Maroochy, give the day one shared moment and let the rest divide naturally.

The early crew

Teens and adults over the minimum ages take a morning snorkel trip to Mudjimba Island.

The young family crew

Parents with small children walk the wetlands boardwalk with a pram, then play at Muller Park.

The paddlers

Confident adults take the Muller Park canoe trail with the tide; beginners paddle Dunethin Lake.

Everyone together

The whole house meets for an afternoon pontoon hire with a meal cooked on board.

Older guests often enjoy the river more than the surf: the boardwalk is step-free, the conservation park walk is rated easy and the largest pontoon is described as walker accessible. Agree one meeting time at the house each day and share tide times in the group chat.

A Two-Day River, Island And Wetlands Plan

This plan assumes a mixed-age group staying in Marcoola. Swap the days around to suit the tide and forecast.

Day One: The Island And The Forest

Early, the snorkel group drives to Mooloolaba for a morning Mudjimba Island trip. Everyone else heads six minutes south to Mudjimba for the conservation park walk, then coffee and the playground on the esplanade.

Regroup at the house for lunch and a pool swim. Late afternoon, walk to Yaroomba Beach and look south towards the island while someone retells the Coolum and Maroochy story.

Day Two: On The Water

On a calm morning, confident paddlers launch at Muller Park for the canoe trail while the rest visit the wetlands boardwalk and meet them at Muller Park for a picnic.

In the afternoon the whole group picks up the 16-seat pontoon from Bradman Avenue for three or four hours on the river, barbecue lit and a few lines in the water. Back at the house, the fenced backyard and pool take over.

If You Have A Third Day

Watch shorebirds from the Cotton Tree side at a weekday low tide, try paddleboarding at Cotton Tree or take beginners to Dunethin Lake. If rain has made the forest track boggy, the wetlands boardwalk is still dry underfoot.

What To Pack For Maroochy River Days

Bring strong insect repellent, light long-sleeved shirts and closed shoes that can get muddy for the wetlands and forest. Add hats, sunscreen, sunglasses with a strap, water bottles and a dry bag for phones and keys on the water.

Anyone prone to seasickness should take their preferred remedy before the island trip, and a warm layer helps after an early spring snorkel. For fishing, pack a measuring ruler, a small esky and the current size limits. Binoculars are worth the space for birdwatchers, and a printed tide table on the kitchen bench saves a big group asking the same question twenty times.

Before You Go: Your Maroochy River Check

1 Tides and wind: Check tide times and the forecast the night before any paddle or pontoon hire.
2 Snorkel trips: Confirm departure times, age limits, prices and the weather call with the operator.
3 Boat hire: Book large pontoons early and ask where you can take the boat.
4 Tracks: Skip the conservation park walk after heavy rain.
5 Fishing: Read the current Queensland size, possession and gear rules.
6 Swimming and dogs: Check patrol times and the council's dog access map.

When the plan is set, check dates and the sleeping layout for Aaron's Beachside Boat House, or compare stays on the WTP book your stay page. The WTP holiday home guides collect every destination guide in one place.
