The Caribbean Sea contains the possibility for you to do many varied aquatic activities, such as deep-sea fishing, boat rides, deep-sea diving, snorkeling, kayaking, etc.  As well as recreational boat trips that offer nighttime shows and romantic dinners.  There are over 25 marine and water sports facilities managed by professional operators and expert guides, with fleets to provide excellent services and a widespread use of sensitive technology that minimize environmental pollution caused by fuel.  It is easy to see why Cancun is a true paradise for water activities.
Be sure to use a good sunblock or suntan lotion, but make sure that it is biodegradable to avoid contaminating the water, so that you leave it in the same pristine condition for future visitors.  
For your safety, always use a life jacket while in the water doing your favorite water sport or activity.
