# The Rock, Racha Noi Island

The Rock is a premier dive site located off Racha Noi Island near Phuket in Thailand’s Andaman Sea. This underwater pinnacle rises from depths of 40-50 meters, making it suitable for experienced and advanced divers seeking dynamic marine encounters.

Divers will discover vibrant coral formations teeming with tropical fish species, including barracuda, trevally, and occasional reef sharks. The site’s rocky structure provides excellent habitat for groupers, snappers, and moray eels. Macro enthusiasts appreciate the abundance of nudibranchs and crustaceans among the crevices.

Strong currents are common at The Rock, requiring solid buoyancy control and navigation skills. The challenging conditions attract large pelagics during seasonal migrations, offering thrilling encounters with whale sharks and manta rays from November to May.
