Belize ... This is called the ATM Tour or ATM Cave. It's amazing, you swim in with headlamps on and climb rocks and ladders to get to different levels. On each 'platform' you observe different artifacts. It's pitch dark inside with flowing water. Once in a lifetime tour, there are 25 guides that go through special training to be allowed to take tourists in the cave.
Though best known as a world-class snorkeling and diving location, Belize also offers spectacular natural attractions and the authenticity of a genuine Caribbean getaway. Nestled between Mexico and Guatemala on the Caribbean coast of Central America, Belize is one of the few remaining unspoiled places on earth.
