Facilities for naturists are classified in various ways. A landed or members' naturist club is one that owns its own facilities. Non-landed (or travel) clubs meet at various locations, such as private residences, swimming pools, hot springs, landed clubs and resorts, or rented facilities. Landed clubs can be run by members on democratic lines or by one or more owners who make the rules. In either case, they can determine membership criteria and the obligations of members. This usually involves sharing work necessary to maintain or develop the site.
