Besides diving interesting sites including a Missionary-era shipwreck (two-tank dives ST275), this family-friendly outfit offers PADI open-water courses (ST1260) and half-day snorkelling tours (ST65, snorkelling gear ST20); turtle and dolphin sightings aren't guaranteed, but they are common. It also hires snorkelling equipment on a casual basis (full set per 24 hours ST30).
