The Tamarin Bay starts at the Tamarina Hotel and goes down to Tamarin's City Center. It is one of the few beaches not protected by coral reefs. It makes it a great snorkelling and surfing spot, although you must remain cautious in the water.
The view of the bay is very scenic, making it ideal for a walk rather than a swim. Since it is surrounded with many 'swimmable' beaches, the Tamarin Bay isn't highly popular and busy even on weekends and holidays.
Go to the Tamarina Hotel's bar for a drink (accessible by car through the main road.) It provides a great view of the Tamarin Bay.
