Smith's Reef is a series of coral heads and reef systems off the north coast near Turtle Cove, about 5.6 kilometres west of Grace Bay. It is the island's second major shore-accessible snorkelling site and, if anything, has more variety than the Bight Reef — the reef systems are larger, the depth range is greater, and the density of marine life can be exceptional.
Access is from two beach points on either side of Turtle Cove Marina. The reef starts in 2-3 metres of water and extends outward to depths of 6-8 metres. The western access point is particularly good for afternoon visits. Nurse sharks rest in the sandy channels between coral heads; eagle rays and green turtles appear regularly. Snorkelling gear is available for rent at several nearby spots.
