Once your flight descends over the Turks & Caicos islands, the first thing you’ll notice is the brilliant, blue Gatorade-colored water that encircles the land masses. There’s no seawater quite like Turks water. Most of the islands are framed by white limestone, and there’s no murky runoff from volcanoes, mountains, or rivers, so the oceans keep their brilliant blues. That’s also partly why you’ll find the world’s third largest barrier reef here. The intricate and colorful underwater landscape makes for awe-inspiring snorkeling and diving opportunities.
