Apart from a watersports store, a large sandy beach plus shower facilities, visitors to this campsite can use these two urinals that are located just next to the cantina... They are flushless and their functionality is explained on a plaque hanging just over the urinals. For the interest of the urinal aficionado, a small history of this sort of device is mentioned on the plaque; 'The composting toilet was invented in Sweden in 1939 by Rikard Lynstroemm (1906 - 1993), ecologist and artist. His invention - the Clivus Multrum - has been used in Canada since the late 1960's. Thanks you for helping to prevent polution of our environment.'"
