Adventures may be activities with some potential for physical danger such as exploring,skydiving, mountain climbing, river rafting or participating in extreme sports. The term also broadly refers to any enterprise that is potentially fraught with physical, financial or psychological risk, such as a business venture, a love affair, or other major life undertakings .
Outdoor adventurous activities are typically undertaken for the purposes of recreation or excitement: examples are adventure racing andadventure tourism. Adventurous activities can also lead to gains in knowledge, such as those undertaken by explorers and pioneers – the British adventurer Jason Lewis, for example, uses adventures to draw global sustainability lessons from living within finite environmental constraints on expeditions to share with schoolchildren. Adventure education intentionally uses challenging experiences for learning.
