In some cases, it can be closely tied to or an extension of, cultural tourism, in other it may be considered a form of agricultural tourism. The literature for it can be found within most of the tourism literature as there is less of it on its own.
To a certain extent there has been a concept of Adventure Tourism for a long time. However, what is considered an "adventure" has changed over time. Generally, Adventure Tourism involves exploration or travel to remote or exotic destinations and/or very unique activities. It is generally grouped into two areas: "hard activities" and "soft activities." "Hard activities" include such activities as water adventures, mountain biking, caving, climbing, etc. while "soft activities" include cycling, camping, water skiing, snow skiing, dude ranches, horse riding etc. Some activities like hiking cycling, backpacking can fit into both hard and soft activities depending on the destination. Like Ecotourism, adventure tourism is an area that is experiencing growth as people's appetite for ever newer and more unique experiences changes. Data for this area is likely to be contained within the larger publications on travel and tourism and may even at times be grouped with ecotourism.
