Cancun's crystal clear sea and surprisingly beautiful and varied underwater world allow you to make the most of the water resources for water-based games and activities. Some of the most popular water activities include not only swimming, but also diving, snorkeling, exploring underground wells, jet skiing, banana and "tire" rides, as well as yacht and boat rides.
For waterskiing, wakesurfing and wakeboarding, head to Laguna Nichupe, west of Cancun. Not only do you have the most favorable conditions, but you can rent all the equipment you need.
In the immediate vicinity of Cancun is Xel-Ha National Water Park, where you can snorkel, ride down the river on a lap boat, swim with dolphins and satisfy your hunger in one of 5 restaurants. At the Underwater Sculpture Museum, you can see the mysterious cenotes for yourself and ride an underwater motorcycle.
