There is good snorkeling in the bay, though the snorkeling at the Blue Lagoon is much better. Many of the local dive operators organise trips to this spot but you can easily walk (see section Beaches above). If the waves are large, don’t bother snorkeling as the current is extremely strong and visibility will be 1 to 3 metres at best. On a calm day expect lots of fish and great visibility. Buoys mark the furthest point snorkelers should go. For even better snorkeling you can charter a boat.
Several places in Padang Bai rent snorkeling equipment.
Padangbai is noted for its diving and the friendly dive centres are right on the beach with their own bars for after-diving refreshments.
