This is the "Split" on Caye Caulker. Caye Caulker is a tiny 5 mile by less than a mile island located 20 miles off the Belize coast. The Split is a popular swimming, snorkeling and tanning hang out for tourist. No trip to Caye Caulker is complete without a visit to the Lazy Lizard for cold tropical beverages and some fun in the sun.
