The 3 islelets of Batutiga, Dakokayu and Naga have the most beatifull coral reefs, with nice table corals and montifora formations (rose-like form corals). There is no real beaches but amazing view from the top of the tree islelets.
Hogow island have a nice, sheltered and very photogenic beach despite it could have a lot of trashes during some seasons. Young peoples from Ratatotok regulary come to clean the beach. The reef around Hogow host a large population of clown fishes on the slope in front of the beach (nemo City). You can also try snorkeling in the mangrove during high tide.
The last island, Salimburung is very rocky with a single and nice beach. The island host lots of birds. The snorkeling is less interesting there that around the others islands of the bay, but confirmed free divers will find huge table corals and massives corals on the east part of the island. Big fishes are often seen around the tables (mackerels, small sharks, big angelfishes...)
