Hamelin Pool

On the edge of the Shark Bay World Heritage Area, Hamelin Pool is one of the most otherworldly landscapes in Australia. This shallow, hypersaline marine basin is home to living stromatolites – ancient microbial structures that resemble lumpy, grey-brown boulders but are in fact living fossils, the oldest known lifeforms on Earth. A boardwalk lets you walk right over the water to observe these primordial mounds, which look like something from another planet. It’s a humbling, mind-bending stop that connects you to 3.5 billion years of life.

Highlights & What to See

• Stromatolite Boardwalk – A 400-metre timber walkway that takes you over the water for close-up views of the living stromatolites. The best light is early morning or late afternoon, when the low sun picks out their textured surfaces.
• Hamelin Pool Telegraph Station – A historic stone building dating from 1884, part of the Overland Telegraph line. Inside is a small museum with displays on the area’s natural and human history.
• Shell Beach – Just a short drive north, this dazzling white beach is made entirely of tiny cockle shells, some 10 metres deep. It’s a surreal, squeaky-clean stretch of shore perfect for a picnic or a swim.
• Stromatolite Interpretation Centre – Located at the telegraph station, it explains how these microbial mats build the rock-like structures through photosynthesis and sediment trapping.

Suggested Time to Spend

Allow 1–2 hours to walk the boardwalk, explore the telegraph station and soak up the strange beauty. If you’re driving from Denham or Monkey Mia, it’s an easy 45-minute detour that works well as a morning or late-afternoon stop. Combine with Shell Beach and Eagle Bluff for a full day exploring the Shark Bay peninsula.

Nearby Areas Worth Combining

• Monkey Mia – Famous for its wild dolphin-feeding program, just a 40-minute drive north.
• Denham – The main town of Shark Bay, with accommodation, supplies and the Ocean Park Aquarium.
• Eagle Bluff – A cliffside boardwalk overlooking a seagrass meadow where you can spot rays, sharks and turtles.
• Francois Peron National Park – Rugged red sand dunes and pristine beaches, accessible by 4WD.
• Kalbarri National Park – About 3.5 hours south, with dramatic river gorges and coastal cliffs.
