Take an underwater ride on your own scooter! On your Breathing Observation Bubble (BOB), you don't have to wear a mask or worry about getting your head wet. Simply sit down, slip on a helmet with a built-in breathing apparatus, and propel down to a shallow seabed in the popular Chitales reef to discover diverse marine life. you'll also have a chance to put on snorkel gear to experience the crystal-clear waters of the reef from another perspective. This combination of a BOB ride and snorkeling offers a unique opportunity to interact with Cancun's colorful tropical fish and living coral at a relaxed pace.
