This cluster of small, uninhabited isles perched at the east end of Mayreau boasts some of Grenadine's finest underwater sites. The remote cays' calm, clear waters teem with bright coral reefs and exotic marine life. In 2006, the area was named a wildlife reserve to maintain its natural setting. As a result, yachts are not allowed to drop anchor here, so you'll feel like you've discovered untouched Caribbean waters. One TripAdvisor user describes the Tobago Cays as "One of the most beautiful places to sail to and simply relax."

A wide variety of diving, snorkeling, and sailing companies offer excursions to Tobago Cays. Friendship Rose Cruise, a reputable charter company, offers full-day sailing and snorkeling excursions via schooner from Bequia to the cays. Boats depart every day at 7 a.m. and return at 5:30 p.m.; breakfast and lunch are included. A full-day cruise costs around $380 XCD (roughly $140 USD) per adult; children under five can sail for free. For more information on the Tobago Cays, visit the SVG Tourism Authority's website.
