There are many variations of urban beaches. Urban beaches are often found along waterways, though some are inserted into town squares or other spaces far from water. The beach may be a seasonal installation over a roadway or parking lot, or it may be permanent. It is not necessarily public land though it is always open to the general public (sometimes with a small admission fee). As river or ocean swimming is not possible, many urban beaches include water features -- for example fountains, wading pools or misting towers -- for cooling off. Some urban beaches feature entertainment, or food and beverage areas. A few include sports facilities such as beach volleyball.
