Tranquility Bay is in one of the most stunning parts of Ambergris Caye. Imagine going pack to AC, four decades ago. No carts, no cobblestone, no restaurants, very little people, very little to no boat traffic, stunning empty beaches. etc... My favorite part of the island in the Bacalar Chico Nature and Marine Reserve. AWESOME place. You are very smart to mix up the in-town/out-of-town experience. Great place for a honeymoon. You can swim to the reef (100 feet) from shore and fabulous snorkeling. Hike up to Robles Point - stellar and climb the 15 foot high bluffs. Hike over 14 miles of trails through the rainforest up there. Do a search on Bacalar Chico and you'll be amazed.
It is far from town.
