Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Historically, Black Rock was celebrated for having one of Maui's most diverse fish populations and was once considered a premier beach dive in the USA.
However, the last decade has seen a reported decrease in reef health and sea life diversity, a condition acknowledged by local operators. Despite these changes, the site still provides a worthwhile experience for certified divers. Commonly approached as a drift dive, it features a prominent reef wall and small caves, extending to a maximum depth of approximately 10 m (32 ft).
Currents, which can run along the shore from north or south, facilitate these drift dives, offering a dynamic underwater journey. Exploring both the left and right sides of the rock face reveals different aspects of the environment, from schools of fish to larger pelagic species.

Depending on the direction of the current and the chosen entry point, diving the left or right side of Black Rock can offer vastly different perspectives on the local ecosystem and topography.
Dive Difficulty & Safety Guidelines
When planning a dive at Black Rock, careful attention to prevailing currents is crucial, as they can run swiftly along the shore. Even surface currents are often noted as strong, requiring divers to be proficient swimmers and aware of their entry and exit strategies. For divers who haven't been in the water for two years or more, completing a scuba refresher course is a prudent step before undertaking an ocean dive. All divers must be certified and capable of carrying their own gear for shore entry. Maintaining good physical health ensures you're prepared for potential challenges presented by environmental conditions.
