Outdoor recreation or outdoor activity refers to recreation engaged in out of doors, most commonly in natural settings. The activities that encompass outdoor recreation vary depending on the physical environmental they are being carried out in. These activities can include fishing, hunting, backpacking, and horseback riding — and can be completed individually or collectively. Outdoor recreation is a broad concept that encompasses a varying range of activities and landscapes.
Outdoor recreation is typically pursued for purposes of physical exercise, general wellbeing, spiritual renewal, and an opportunity to partake in nature whilst doing so. While a wide variety of outdoor recreational activities can be classified as sports, they do not all demand that a participant be an athlete. Rather, it is the collectivist idea that is at the fore in outdoor recreation, as outdoor recreation does not necessarily encompass the same degree of competitiveness or rivalry that is embodied in sporting matches or championships. Competition generally is less stressed than in individual or team sports organized into opposing squads in pursuit of a trophy or championship.
When the activity involves exceptional excitement, physical challenge, or risk, it is sometimes referred to as "adventure recreation" or "adventure training", rather than an extreme sport.
Other traditional examples of outdoor recreational activities include hiking, camping, mountaineering, cycling, dog walking, canoeing, caving, kayaking, rafting, rock climbing, running, sailing, skiing, sky diving and surfing. As new pursuits, often hybrids of prior ones, emerge, they gain their own identities, such as coasteering, canyoning, fastpacking, and plogging.

In many cities, recreational areas for various outdoor activities are created for the population. These include natural parks, parks, sports facilities but also areas with free sea access such as the beach area of Venice Beach in California, the Promenade des Anglais in Nice or the waterfront of Barcola in Trieste.
