The Snake Pit is a legendary dive and snorkel site on the outer Ribbon Reefs, north of Lizard Island on the Great Barrier Reef. This dramatic underwater canyon funnels powerful tidal currents, attracting vast schools of pelagic fish and its namesake — the iconic olive sea snake. Renowned for adrenaline-charged drift snorkeling, the site plunges through coral-lined walls where reef sharks, giant trevally, and barracuda patrol the surge. The sheer abundance of marine life and the unique chance to encounter sea snakes in their natural habitat makes The Snake Pit a bucket-list destination for experienced snorkelers visiting the remote northern Great Barrier Reef.
