Hanauma Bay is one of the most biologically diverse regions on our planet. Thanks to the rich volcanic soil, the warm tropical climate and the massive reef system, visitors to the bay will enjoy seeing an abundance of sea life in an idyllic environment.

Snorkelers must be careful to not disturb the coral as it is the lifeblood of the bay.  The basic rule is: Look but don't touch!
