About this experience
What makes this tour unique is the opportunity to snorkel at Sombrero Reef, one of the Florida Keys’ most beautiful and expansive coral reef systems. After cruising approximately four nautical miles offshore aboard a 31-foot motorized catamaran, guests spend about 45 minutes exploring a vibrant underwater ecosystem filled with mature coral formations, colorful tropical fish, sea fans, sponges, rays, sea turtles, and other marine life. The combination of a scenic offshore boat ride, an uncrowded open-water setting, and the chance to experience a thriving natural reef makes this more than a typical snorkeling trip. It offers guests an up-close look at the incredible marine environment that makes the Florida Keys so special.
