Apnea or free diving it’s a sport, on which the base is the voluntary suspension of breathing under water as you cover certain distance or you descend great depths. Even though for some people this might feel like physical training, the sport of apnea allows you to explore the marine world without Scuba equipment needed. Depending on the capacities of each person Isla Mujeres counts with several diving sites with different depths on which you can practice this fun activity always under supervision of an experienced guide.
