Camping as a recreational activity became popular in the early 20th century. Campers frequent national or state parks, other publicly owned natural areas, and privately owned campgrounds. Camping is a key part of many youth organizations around the world, such as scouting. It is used to teach self-reliance and teamwork.
Camping is also used as an inexpensive form of accommodation for people attending large open air events such as sporting meetings and music festivals. Organizers often provide a field and other basic amenities.
