'Dell' is an Old English word for a valley, usually surrounded by woods. That is precisely what Great Dell is. Mostly flat, with a rising path that reaches a wooden aerial walkway looking down on the dell space. There are all manner of giant trees and bushes from around the world, that create a bright green canopy that shelters the entire place from the sun. Its gently sloping sides give the dell a cosy and intimate feel, and there is plenty of space for all.
