Providenciales offers some great snorkelling right from the beach. Generally, the best snorkelling reefs are off the north coast, but there are quite a few interesting sites elsewhere as well. See detailed information on the main locations below.
1 Lightly brush lemon wedges with some of remaining dressing and grill, turning over once, until grill marks appear, 3 to 5 minutes. Transfer to a large platter.  Grill shrimp on lightly oiled grill rack (covered only if using a gas grill), turning over once, until just cooked through, 7 to 8 minutes total.
(If using wood skewers, soak them in water for 10 minutes beforehand.) In a small bowl, combine the butter and garlic. Brush the shrimp with the garlic butter. Place the shrimp on grill with the limes. Cook for about 4 minutes on each side or until the shrimp are opaque and the limes are browned. Remove from grill.
