Geocaching in the context of GPS navigation device

Outdoor literature is a literature genre about or involving the outdoors. Outdoor literature encompasses several different subgenres including exploration literature, adventure literature and nature writing. Another subgenre is the guide book, an early example of which was Thomas West's guide to the Lake District published in 1778. The genres can include activities such as exploration, survival, sailing, hiking, mountaineering, whitewater boating, geocaching or kayaking, or writing about nature and the environment. Travel literature is similar to outdoor literature but differs in that it does not always deal with the out-of-doors, but there is a considerable overlap between these genres, in particular with regard to long journeys.

Adventure travel is a type of tourism, involving exploration or travel with a certain degree of risk (real or perceived), and which may require special skills and physical exertion. In the United States, adventure tourism has seen growth in late 20th and early 21st century as tourists seek out-of-the-ordinary or "roads less traveled" vacations, but lack of a clear operational definition has hampered measurement of market size and growth. According to the U.S.-based Adventure Travel Trade Association, adventure travel may be any tourist activity that includes physical activity, a cultural exchange, and connection with outdoor activities and nature.

Adventure tourists may have the motivation to achieve mental states characterized as rush or flow, resulting from stepping outside their comfort zone. This may be from experiencing culture shock or by performing acts requiring significant effort and involve some degree of risk, real or perceived, or physical danger. This may include activities such as mountaineering, trekking, bungee jumping, mountain biking, cycling, canoeing, scuba diving, rafting, kayaking, zip-lining, paragliding, hiking, exploring, Geocaching, canyoneering, river trekking, sandboarding, caving and rock climbing. Some obscure forms of adventure travel include disaster and ghetto tourism. Other rising forms of adventure travel include social and jungle tourism.

Benchmarking, also known as benchmark hunting, is a hobby activity in which participants find benchmarks (also known as survey markers or geodetic control points). The term "benchmark" is used only to refer to survey markers that designate a certain elevation, but hobbyists often use the term benchmarks to include triangulation stations or other reference marks. Like geocaching, the activity has become popular since 1995, propelled by the availability of online data on the location of survey marks (with directions for finding them) and by the rise of hobbyist-oriented websites.

In 2022 Geocaching HQ informed that they will remove Benchmarking from the Geocaching.com website.
