Getting there
The island is reached by boat from Teknaf, the southernmost point of the mainland, itself about a 4–5 hour drive or bus ride south of Cox's Bazar. The sea crossing takes roughly 2.5 to 3 hours each way, and boats generally run only during the dry season (November through March), when the sea is calm enough for the crossing.
Most visitors do this as a long day trip from Cox's Bazar, though staying overnight on the island is the better way to actually see it without rushing.
What to do
The main draw is the coral-fringed shoreline itself — clear, shallow water over coral patches makes for the closest thing to reef snorkelling Bangladesh offers, best done in the calmer waters around Chera Dwip, a smaller islet connected to the main island at low tide.
- Chera Dwip — a smaller islet connected to the main island at low tide, with the calmest water and the best of the coral snorkelling.

- The island loop road — a few hours to cycle or walk, passing fishing villages, coconut groves, and small guesthouses along the way.
Cycling or walking the island's single loop road takes only a few hours and passes through fishing villages, coconut groves, and small guesthouses along the way. Fresh seafood, caught and grilled the same day, is the other reason people stay overnight rather than day-tripping.
Best time to visit
November through February is the reliable window — calm seas, dry weather, and full boat service from Teknaf. Boat services typically stop entirely during the monsoon (roughly June through September), when the crossing becomes too rough, so this isn't a year-round destination the way some of Bangladesh's other beaches are.
Practical notes
Accommodation on the island is limited and basic compared to Cox's Bazar — simple guesthouses rather than resort-style hotels — so booking ahead during the November–February season matters, especially around winter holidays when capacity fills fast. There's no ATM on the island, so bring cash from Teknaf or Cox's Bazar. Boat departure times shift with tides and weather, so treat any schedule as approximate until you're actually at the Teknaf jetty.
