Located off the Pilbara Coast 120km west of Dampier and 139km north of Onslow, the Montebello Islands Marine Park covers more than 58,000 hectares of ocean and over 250 low-lying limestone islands and islets.
The area is rich in natural marine diversity and human history, and fishers, snorkellers and divers are attracted to its coral reefs, colourful tropical fish, wildlife and maritime heritage. The only way to access the Montebello Islands is by boat, with fishing charters operating from Karratha.
The Montebello Islands Marine Park is zoned for different uses, with sanctuary, special purpose, recreational and general use zones. Parks and Wildlife have produced maps and a Marine Park app to assist visitors.
Atomic tests were carried out at the Montebellos in 1952 and 1956. Due to slightly elevated radiation levels on Trimouille and Alpha Islands, visitor should restrict their visits to one hour per day.
Camping is allowed on Primrose, Bluebell, Crocus, Hermite & Renewal Islands (year-round) & Northwest Island (April-Sept); within 100m of hightide mark, up to 5 nights. No pets or open fires.
