Secluded beaches, crystal-clear waters, plunging cliffs and diverse plant communities are some of the attractions of Keppel Bay Islands National Park and Keppel Bay Islands National Park (Scientific).

Keppel Bay is studded with islands. The two largest islands, Great Keppel (1454ha) and North Keppel (627ha), are surrounded by 16 smaller islands and several prominent rocky outcrops. Keppel Bay Islands National Park includes 13 islands, although it does not include Great Keppel Island. Barren and Peak islands form the Keppel Bay Islands National Park (Scientific). Steep hills and cliffs, which plunge into the sea, are features of the islands but there are also sheltered bays and quiet sandy beaches. Vegetation ranges from open grassland and heathland to tall, shady forests and dense, low rainforests.

The Great Barrier Reef Marine Park surrounds the Keppel Bay islands. Together they form part of the Great Barrier Reef World Heritage Area, the world's largest reef and island system. It is of exceptional beauty and biological diversity, protecting many endangered animals and plants.
