The Kagerplassen is a system of peat lakes in the north of the Dutch province of South Holland, which is used as a recreational and fishing area. The lakes lie between Warmond, Oud Ade, the Haarlemmermeer and Sassenheim, mostly in the municipality of Teylingen. Bordered by a network of small reed ditches and canals, the lakes are part of the Dutch-Utrecht peat meadow area. There are many and relatively large islands in – and between – the lakes. At Caya Island, there are numerous options for docking and lunch and/or dinner.
