Dhidhdhoo Island is a quiet local island with one shop, one guesthouse, and two cafes. It is very close to Whale Shark Point, so is ideal for boat excursions to see them and Manta Rays as well. When not out on excursions, there is some nice snorkeling opportunity on the house reef. The coral is not stunning, but there is plenty of marine life to see across the reef and over the drop off.

How to get to Dhidhdhoo Island snorkeling spot?

Dhidhdhoo is a small inhabited island in the southern part of Ari Atoll. It is frequently called Adh Dhidhdhoo (for Alif Dhaal Atoll, also known as South Ari Atoll).

Dhidhdhoo Island is just 2 miles east of Maamigili, a larger inhabited island known for hosting the Whale Shark Point snorkeling location along its southern coast. The best snorkeling area in Adh Dhidhdhoo is located on the inner reef, east of the harbor.

Water entrance for snorkeling Dhidhdhoo Island

The water entrance is only from the harbor.  Walk out atop the harbor wall to the corner where there is a gap in the wall and a sloping entrance over large rocks. There is no beach access.

The current usually flows towards the southwest along the coast, so most of the time swimming out from the harbor takes a little effort, and coming back in is a breeze.

Dhidhdhoo Island snorkeling exploration tips

The main snorkeling area at Adh Dhidhdhoo extends east of the island’s harbor. It comprises a large reef flat covered with seagrass and small corals, as well as an almost vertical drop off.

The reef flat is very shallow, with a maximum depth ranging between 1 and 6 feet (0.5 to 2 meters) depending on tides. In this area, you may spot boxfish, batfish, and occasional stingrays, and nurse sharks.

The reef top ends at a drop-off, the wall dropping down to more than 33 feet / 10 meters.
