English: Restaurant Kraantje Lek in Overveen, Bloemendaal, the Netherlands. The black sculpture is the tarred over remains of a monumental tree known locally as the "Holle boom" which finally died in the 1990's. Behind the tree a large sand dune can be seen. A flight of stairs takes the visitor to a view of the park Kennemerduinen and the trail "Visserspad". This particular dune is a popular place for various sports clubs in the area who train by running up and down this sand dune and along the trail (which leads to Zandvoort). To the right (not shown) one of three public water fountains at the edge of the dunes park is often used by joggers, cyclists and dog owners in the summer months (during the winter it is turned off).
