Camp Wirribara is located on the shore of Little Clear Lake in Boulter township. This is a kettle lake that was formed by the last ice age. There are no creeks or streams going into or flowing out of it. It is spring fed and has a sandy bottom and is stocked with trout. This lake is about 40 acres in area.
The four acre property is part of the Boulter Esker, one of the largest esker in Ontario. The surrounding property is Crown Land as is most of the township. The area was reforested in the 1940 with red pine. It abounds with wildlife and many species of birds. Boulter borders Algonquin Park.
