Mushroom Rock - Rainbow Valley
Comprehensive information on the Coral Coast region including destinations, things to see and do, accommodation and tours.

Kalbarri National Park’s coastline features dramatic Tumblagooda sandstone cliffs plunging into the Indian Ocean. The coastal heathlands and rugged cliff tops of the park boast an astonishing level of biodiversity. From July to October, the area erupts in vibrant color, with several hundred recorded native species. Prominent blooms include the iconic Kalbarri Catspaw, pink pokers, feather flowers, banksias, grevilleas, and various endemic orchids (such as the Kalbarri Spider and Cowslip orchids). You'll also spot coastal ray flower, purple thryptomene, and wooly orange banksia dotting the sandy plains.
The coastline and surrounding waters are a haven for both marine life and coastal birds. During the migrating season (June to November), humpback whales and southern right whales can be frequently spotted from the coastal cliff lookouts. Bottlenose dolphins and Australian sea lions also inhabit the local waters. Keep an eye out for wedge-tailed eagles, ospreys, and sea eagles soaring the coastal thermals. The unique black-flanked rock-wallaby, western grey kangaroos, and echidnas can occasionally be seen near coastal paths like the Bigurda Trail.
