Dives run to 35 m with around 20 m visibility, gentle currents and sea temperatures of 16–25°C. Marine highlights include volcanic rock formations, rays and corals.

Came hoping for volcanic rock formations, and it delivered. The 20 m visibility kept everything sharp.
A great teaching site: the 20 m visibility and the gentle profile let newer divers build confidence.
Worth the journey — the May–Oct window is the time to go.
