There are many destinations specializing in this type of tourism, and the truth is that thanks to several television programs that exist around the world, it is a tourism that is gaining more followers every day.
Here are some of the most popular extreme adventure tourism destinations where you will undoubtedly live a unique experience:

– Diving among sharks : You can do it in many destinations but one of the best known is La Digue Island, which is in the famous Scheylles Islands. Calm and paradisiacal waters that in some areas offer the opportunity to take a dip among some of the most dangerous animals in the world. Undoubtedly an experience not suitable for "freaks."

The ideal occasion to combine paradisiacal beaches with all the possible relaxation and an incredible adventure that will take you to see the most beautiful landscapes in the area.
