Everything you need to know about this dive site.
Dive Site Overview
Wash Rock unfolds as a multi-faceted dive, combining distinct geological features with a thriving reef ecosystem. Diving often commences with a descent into a captivating lava tube, an overhead environment divers can navigate with a guide's torch.
This passage, home to various crustaceans and smaller fish, leads through an intriguing submarine landscape. Exiting the lava tube, the route typically crosses a sand channel. That sandy expanse, despite its seemingly barren appearance, often reveals hidden life, including moray eels tucked beneath rocky outcrops.
Wash Rock itself then becomes the main event, a prominent pinnacle and reef structure reaching a maximum depth of 6 m / 21 ft. Its varied surfaces host a colorful collection of corals and sponges, supporting a rich diversity of reef fish.
A common dive plan involves circumnavigating the pinnacle before returning towards the mooring, allowing ample time to appreciate its distinct features and resident marine life.
