Yalgorup National Park Walks: Lake Pollard, Heathlands, Thrombolites

Why Yalgorup Is Preston Beach's Backyard

The Shire of Waroona describes Preston Beach as bounded by the Indian Ocean, Lake Preston and Yalgorup National Park. In practice that means the national park starts almost at the edge of town. You can be on a trail within minutes of leaving the house, and the lake you see from the Heathlands lookout is the same one that stretches along the eastern side of the settlement.

The name comes from Noongar words. The DBCA park brochure explains that yalgor means a swamp or lake and up means a place of, so Yalgorup is, fittingly, a place of lakes. DBCA notes that the park is the traditional land of the Pinjarup people, and the state government's 2026 announcement about Lake Clifton refers to the deep cultural importance of the thrombolites to the Bindjareb people.

The park also has international standing. DBCA says its lakes are recognised under the Ramsar Convention as wetlands of international importance, largely because of the waterbirds they support, including migratory waders.

For visitors, the appeal is simple. Within a short drive you get lake lookouts, bird hides, wildflowers on limestone ridges, tuart and peppermint woodland and one of the rarest natural sights in Australia, all on trails that most people can finish before lunch.

How The Lakes Fit Together

It helps to understand the layout before you pick a walk. The DBCA brochure describes a chain of lakes forming three distinct lines running parallel to the coast. It names Lake Preston, Swan Pond, Duck Pond, Boundary Lake, Teal Lake, Lake Pollard, Martins Tank Lake, Lake Yalgorup, Lake Hayward, Newnham Lake and Lake Clifton among them.

Lake Preston is the one closest to the sea and, as DBCA's site page puts it, extremely elongated. It runs behind the dunes for a long way, which is why it dominates the view from Preston Beach and the Heathlands lookout. The Shire says it is about nine times more saline than the ocean.

The landscape between the lines of lakes comes from two dune systems. DBCA explains that the limestone rocks and soils inland are from the older Spearwood dune system, formed over roughly the past 10,000 to 140,000 years, while the Quindalup dunes nearer the coast have been blown in or washed ashore over the past 10,000 years. You feel that difference on the trails: sandy tracks through coastal heath, then firmer limestone ridges with wildflowers.

One rule applies to every lake. DBCA's visitor guide is clear that there is no access to the lakes for swimming, boating or fishing. Save the swimming and fishing for the ocean at Preston Beach.

Heathlands Walk Trail: The Closest Big View

If you only do one walk from Preston Beach, make it Heathlands. Trails WA says it starts from the Heathlands Walk Trail car park on Preston Beach Road, just off the Forrest Highway, so it is on your way in or out of town. The DBCA visitor guide lists it as a 4.6km walk of about 1.5 hours, graded Class 3, meaning moderately difficult with short steep sections.

Trails WA describes a loop signed for walking clockwise. The route climbs gently over a limestone ridge, and a side track leads to a lookout with views across Lake Preston to the ocean. A second spur drops through what Trails WA calls a tunnel of trees right to the water's edge. Along the way you pass coastal heath, paperbarks and tall eucalypts.

Spring is the season to do it. Trails WA puts the peak wildflower display from August to October, and DBCA's picnic-area page describes a trail that runs from tall tuart trees to wildflowers on limestone ridges. There is a picnic table and information bay at the start, which makes it easy to turn the walk into a morning tea stop.

Two cautions. Trails WA warns that snakes are present, so stay on the track, and walkers on AllTrails mention mosquitoes near the lake edge. Wear closed shoes and bring repellent.

Lake Pollard Walk Trail: Bird Hide And Black Swans

Lake Pollard is the birdwatcher's walk. Trails WA places the trailhead about 6km along Preston Beach Road North, near the Martins Tank campground entrance, so it is another short drive from town. DBCA lists it as a 6km walk of about two hours, graded Class 2 with gentle gradients.

Trails WA recommends walking the loop clockwise for the best lake views. The first half runs through forest with tuart, peppermint and grasstrees, and a short spur leads to a wooden bird hide on stilts at the edge of the lake. The second half follows a firebreak and then a wide crushed-limestone road back along Preston Beach Road, which Trails WA notes is less scenic. If you are mainly there for the birds, walking to the hide and retracing your steps is a sensible alternative.

The headline sight is black swans. DBCA's visitor guide says Lake Pollard is renowned for its high numbers of black swans between October and March. Trails WA also mentions hooded plovers and white-fronted chats around the hide. Bring binoculars and give yourself time to sit quietly rather than rushing the loop.

There are picnic facilities at the trailhead. Trails WA notes that the nearest public toilets and gas barbecues are at the Preston Beach car park.

Lake Clifton Thrombolites And The Lakeside Loop

The Lake Clifton thrombolites are the most famous thing in Yalgorup, and they are worth the short drive north. DBCA describes Lake Clifton as having the largest known community of living thrombolites in the southern hemisphere, with population densities of up to 3,000 per square metre. They look like low grey rocks in the shallows, but they are built by micro-organisms similar to some of the earliest life forms on earth.

The WA Government describes the thrombolites as a threatened ecological community. For the Bindjareb people they are Noorook, the eggs of the Wagyl, the creation snake. DBCA's visitor page explains that an observation walkway protects them from direct contact, and that they are harder to see when the water level is higher, so viewing is usually better when the lake is lower.

The Lakeside Loop starts at the same site on Mount John Road. DBCA lists it as a 5km, two-hour Class 2 walk, and Trails WA describes it running parallel to the eastern shore of Lake Clifton through paperbarks, peppermints and tuart, with interpretive signs along the way. DBCA's guide measures the thrombolites turn-off at about 32km south of Mandurah, compared with 55 to 60km for the Heathlands and Lake Pollard trails, and the Preston Beach Coastal Escape listing puts the thrombolites boardwalk about 20 minutes' drive from Preston Beach.

One important update: in June 2026 the WA Government announced a $3.4 million replacement boardwalk at Lake Clifton, with 145 metres of elevated timber boardwalk and a 50-metre connector path, expected to be finished in early 2027, subject to weather and site conditions. The announcement did not say whether access will change during the works, so check DBCA's Lake Clifton Thrombolites page for alerts before you drive up.

Lime Kiln Lake Trail: A Century Of History In 1.2 Kilometres

The Lime Kiln Lake Trail is the easiest walk in the park and a good pairing with the thrombolites. DBCA says it starts at the Historic Lake Clifton Lime Kiln picnic area, off Newnham Road near Old Coast Road on the east side of Lake Clifton. It is a 1.2km return walk that DBCA describes as accessible for people of all abilities, with benches along the way.

The story is an interesting one. DBCA explains that the Western Australian Portland Cement Company built the kiln on site in 1922 as part of a lime-processing operation that ran from 1919 to 1923. The venture failed when the deeper lake deposits proved unsuitable for making cement. You can still see the square outlines of old settling ponds, and near the lake edge there may be old mooring sticks and dredging remnants.

About 100 metres along the trail is a talking circle with Noongar seasonal artwork, a good place to stop and talk with children about the six Noongar seasons. In spring, DBCA mentions wildflowers such as white bunny orchids along the path.

Plan ahead for one practical gap: DBCA notes there are no toilets at the Lime Kiln picnic area and all rubbish must be taken away with you.

Which Walk Suits Your Group

Each trail has a different character, so match the walk to the people rather than trying to do all four in one day.

A good two-morning plan is Heathlands or Lake Pollard on the first day, close to home, and the thrombolites plus Lime Kiln on the second, as one trip north.

Birdwatching Across The Yalgorup Lakes

Birds are the reason the lakes are Ramsar-listed. DBCA's brochure mentions high numbers of musk ducks, Pacific black ducks, black swans and shelducks, and the visitor guide lists migratory waders including bar-tailed godwits, red-necked stints and greenshanks.

The Lake Pollard hide is the most comfortable place to watch, because you can sit out of the wind and let the birds settle. The Heathlands lookout gives a wider view across Lake Preston, which is better for spotting movement than identifying species.

Bring binoculars, a simple field guide or app, and patience. Early mornings are usually best. Keep noise down near the water and never approach nesting birds.

Bird numbers change with water levels and seasons, so treat a big swan count as a bonus rather than a promise.

Kangaroos, Emus And Other Wildlife

Yalgorup is home to far more than birds. Wildlife recorded in the park includes western grey kangaroos, emus, brush wallabies, brushtail possums, echidnas and bandicoots. Tourism Western Australia notes that golfers at the Preston Beach course often share the fairways with kangaroos and emus, so you may not even need to reach a trailhead to see them.

Kangaroos are most active around dawn and dusk. That is lovely on a walk but important on the road. Drive slowly on Preston Beach Road, Preston Beach Road North and Old Coast Road at those times.

Spring also brings reptiles out. Snakes are present in the park, as Trails WA warns for Heathlands. Stay on the track, watch where you step, and give any snake plenty of room to move away.

Never feed wildlife. It harms the animals and teaches them to approach people and cars.

Park Rules That Catch Visitors Out

Dogs. DBCA states that pets are not permitted in national parks, and its Yalgorup pages warn of ongoing 1080 baiting to control foxes and feral cats. 1080 is poisonous to humans and will kill domestic cats and dogs. If you are travelling with a dog, walk the trails while someone else stays with it, and keep dog time for the beach.

Water. DBCA says no drinking water is available anywhere in the park. Its visitor guide recommends drinking 3 to 4 litres of water per day when walking.

The lakes. No swimming, boating, canoeing or fishing in any of the lakes. This protects the birds and the fragile shorelines.

Martins Tank. The campground near Lake Pollard is for booked campers only. DBCA says day use without a booking is not permitted and picnic facilities are not provided there, so use the Lake Pollard trailhead instead.

Valuables. DBCA advises not to leave cash or valuables in your car at the thrombolites car park, which is sensible advice at any trailhead.

When To Walk And How To Stay Safe

Spring is the sweet spot. Wildflowers peak from late winter into spring, swans are building up on Lake Pollard, and the days are mild enough for a midday walk.

Summer needs more care. DBCA's Martins Tank page warns that December to April can be extremely hot and the bushfire risk can be very high. In those months walk early, carry more water than you think you need and check for fire alerts and park closures before leaving.

DBCA also notes that storms are common from May to October. Check the forecast, avoid walking in lightning, and be ready to turn back if the weather changes.

Tell someone your plans, stay on marked trails and consider a personal locator beacon, as DBCA suggests for its Yalgorup sites.

Who A Yalgorup Walking Stay Suits

Couples and friends who like a morning walk followed by a long lunch will find the Heathlands and Lake Pollard trails ideal, with no need for serious hiking gear.

Families can mix the easy Lime Kiln trail and the thrombolites boardwalk with beach time, which keeps young legs happy and adds a bit of science and history to the trip.

Birdwatchers and photographers get a Ramsar wetland with a proper bird hide, plus sunrise and sunset light over long lakes.

Older travellers or anyone with limited mobility can still enjoy the park through the accessible Lime Kiln trail and the thrombolites viewing walkway.

Where Preston Beach Coastal Escape Fits A Walking Stay

Preston Beach Coastal Escape is a renovated, single-level two-bedroom, two-bathroom house on the lake side of Preston Beach, sleeping up to five guests. The listing describes 180-degree views over Lake Preston and Yalgorup National Park, with the Darling Scarp on the eastern horizon. For walkers, that outlook is a nice bonus: you spend the morning on a lake trail and come home to the same lake and bushland from the deck.

The trailheads are close. The listing puts the Lake Preston Walking Trail about 5 minutes' drive away, the Heathlands Walk about 8 minutes, Martins Tank Lake and campground about 10 minutes, the Lake Pollard Trail and bird hide about 12 minutes and the Lake Clifton thrombolites boardwalk about 20 minutes. Preston Beach itself is about a 12-minute walk through the dunes, which makes an easy afternoon option after a morning on the trails.

After a walk, the covered timber gazebo deck, with its long outdoor dining table, wicker lounge and festoon lights, suits a slow lunch outdoors, and the undercover outdoor kitchen has a gas barbecue, bench and sink. On cool mornings or evenings there is an indoor wood heater with starter firewood and split-system air conditioning in both bedrooms and the living room. A washing machine and clothes drying rack handle dusty walking clothes, and the outdoor shower rinses off sandy feet.

Wildlife starts at the fence line: the listing says kangaroos, ringneck parrots and kookaburras visit the garden. One dog is welcome by approval in a fully fenced yard, but dogs cannot go into Yalgorup and the house rules ask that dogs are not left alone at the property, so plan to take turns on the trails.

See photos, current rates and open dates on the Preston Beach Coastal Escape listing.

How A Small Group Uses The House Between Walks

The sleeping setup is a queen bedroom with its own ensuite and a bay window looking towards Lake Preston, and a second bedroom with a tri-bunk (a double bed below and a single above) served by the main bathroom. A couple with up to three children fits comfortably, or a couple plus a friend or parent, each with a bathroom.

The renovated kitchen, with a stone island, gas cooktop, oven and dishwasher, plus a scullery and a coffee and tea station, makes it easy to pack a trail picnic in the morning and cook dinner at home at night. That matters here, because Preston Beach is a small community with limited dining, and the listing notes that Woolworths and Coles online grocery orders deliver to the address.

Starlink Wi-Fi reaches every room and there is a laptop-friendly workspace, which suits anyone planning a midweek stay: an early walk, a few hours of work, then the beach before sunset.

Board games, a smart TV and a sound system cover the evenings, and the wood heater is welcome after a cool spring day outside. On total fire ban days the house rules say the wood heater cannot be lit, so check Emergency WA in the warmer months.

A Two-Day Yalgorup Walking Plan From Preston Beach

Day One: Heathlands And The Beach

Drive the short distance to the Heathlands car park on Preston Beach Road after an early breakfast. Walk the 4.6km loop clockwise, taking the side track to the Lake Preston lookout. Have morning tea at the picnic table, then head home for lunch on the gazebo deck and an afternoon walk to the beach.

Day Two: Lake Pollard, Thrombolites And The Lime Kiln

Start at first light at Lake Pollard and walk to the bird hide, returning the same way if you want to save time. Mid-morning, drive north to the Lake Clifton thrombolites and walk the Lakeside Loop, or simply the viewing walkway if energy is low. Finish at the Lime Kiln Lake Trail before a late lunch, remembering there are no toilets at the Lime Kiln site.

Optional Extra Morning

If you have a third day, repeat your favourite walk at a different time of day. Lake Pollard at sunrise and Heathlands in the late afternoon feel like completely different places.

What To Pack For Yalgorup Walks

Bring at least 3 to 4 litres of water per person for a full walking day, as DBCA recommends, because there is none in the park. Pack snacks or a picnic, a hat, sunscreen and insect repellent.

Closed shoes with good grip are important on Heathlands, where the limestone sections are steeper. Long, light trousers help with scratchy heath and with snakes in spring and summer.

Binoculars make a big difference at the Lake Pollard hide and the Heathlands lookout. A camera with a zoom lens is useful for swans and waders.

Take a rubbish bag, since some sites, including the Lime Kiln picnic area, have no bins or toilets. A charged phone, a basic first aid kit and a personal locator beacon for longer outings round out the list.

Plan Your Walking Stay

If a few mornings on quiet lake trails sounds like the right kind of break, check availability at Preston Beach Coastal Escape, a lake-view base close to the Heathlands and Lake Pollard trailheads. You can browse every WTP stay on the WTP Holiday Homes booking page and find more ideas in the WTP holiday home guides.

When you are ready, see dates for the Preston Beach lake-view house and plan your walks around the season.
