Blue Holes is a protected marine sanctuary located just south of Kalbarri on Western Australia’s Coral Coast. Renowned for its calm waters, shallow rock pools and abundant marine life, it offers one of the safest and most accessible coastal swimming and snorkelling experiences in the region - particularly for families with children.
The best time to visit is during low tide (for the safest conditions), or mid tide sees more of the pools become connected. We recommend visiting in the morning for low winds and good lighting - as the sun's rays shine through the pools, illuminating the marine life.
The area takes its name from a unique limestone reef system that runs close to the shoreline. This natural reef creates a series of permanently submerged pools and exposed platforms, forming a sheltered environment that acts like a natural aquarium. As a designated Fish Habitat Protection Area, Blue Holes supports exceptional biodiversity and crystal‑clear conditions ideal for snorkelling and underwater exploration.
More than 70 species of finfish are recorded at Blue Holes, along with coral and sponges growing across the limestone reef. Commonly seen species include spot dart, moon wrasse, raccoon butterflyfish and humbugs, as well as western rock lobster, banded hair shrimp and oyster beds. Surveys have identified 11 species of coral and 10 types of sponge, reflecting the area’s diversity and suitability for snorkelling in calm, shallow waters.
On land, a pristine stretch of white sand invites relaxed beach walks and rock‑pool discovery at low tide. Visitors can swim in the tranquil waters, bask in the sunshine or simply enjoy the unspoilt coastal setting. As evening approaches, Blue Holes becomes a spectacular place to watch a classic Western Australian sunset over the Indian Ocean.
Blue Holes is approximately a six‑hour drive north of Perth and just minutes from Kalbarri, making it an easy and memorable stop on any Coral Coast road trip.
