Do not leave your belongings on the beach while you are swimming. Keep your passport and other valuables in the hotel safe. Visitors to Mexican resorts should carefully assess the risk potential of recreational activities. Sports and aquatic equipment that you rent may not meet U.S. safety standards nor be covered by any accident insurance. For example, unless you are certain that scuba diving equipment is up to standard, do not use it.
Safe diving requires lengthy training.
Parasailing is offered at many Mexican beach resorts. Be aware that by putting your name on the passenger list, you may be relieving the boat operator and owner of responsibility for your safety. There have been cases in which tourists have been dragged through palm trees or slammed into hotel walls while participating in the activity. Be extremely careful when renting jet-skis. Several tourists have been killed or injured in jet-ski accidents, particularly when participating in group tours.
