Adventure sports or extreme sports, as they are often called are sports that have a higher level of danger, excitement and skill and activities that require participants to combine athletic skill with pronounced risk. Adventure sports have become increasingly popular since the 1990s, with a wide range of sports taking place in the water, on land and in the air.
