Diving and snorkelling are the reasons people come to Rasdhoo. The Rasdhoo Channel is the best-known dive in the area — known for early-morning hammerhead shark sightings — and the house reef off the southern beach is reachable on a short swim. Local dive shops run two- or three-tank trips daily.
Off the water, the village is small enough to walk around in 20 minutes. Excursions to nearby uninhabited islands and resort reefs are easy to arrange — Madivaru and Veligandu are short panga rides away, and a half-day trip to a sandbank at low tide is a classic.
