Montebello Islands Marine Park

Montebello Islands Marine Park is a protected marine reserve off the Pilbara coast of Western Australia, about 120 kilometres west of Dampier and 20 kilometres north of Barrow Island. Covering 58,722 hectares and encompassing 265 limestone islands and islets, it is renowned for pristine coral reefs, turquoise waters, diverse marine life and important turtle nesting sites. The park is managed by the Department of Biodiversity, Conservation and Attractions and is accessed only by private boat.

Visitors can expect a remote, undeveloped archipelago of low limestone islands surrounded by clear turquoise water, fringing coral reefs, lagoons, and white sandy beaches. There are no shops, accommodation or developed visitor infrastructure. Access is only by private boat, typically as a multi-day charter from Dampier, Onslow or Karratha. Activities centre on the water including snorkelling, diving, fishing and wildlife observation. Visitors will see abundant marine life, seabirds and turtle nesting areas, and can explore sheltered bays and reef passages.
