Brownsea Island

Brownsea Island (also archaically known as Branksea) is the largest of the islands in Poole Harbour in the county of Dorset, England. The island is owned by the National Trust. Much of the island is open to the public and includes areas of woodland and heath with a wide variety of wildlife, together with cliff top views across Poole Harbour and the Isle of Purbeck.

The island is most notable as the home of the experimental camp in 1907 that preceded (and led to) the formation of the Scout movement in 1908. Access is by public ferry or private boat; in 2002 the island received 105,938 visitors. The island's name comes from Anglo-Saxon Brūnoces īeg = "Brūnoc's island".
