Once used as a fire lookout, today the 61-metre high Gloucester Tree is one of Pemberton's best loved tourism attractions - sensational views from the top and if you make it to the tree's lofty crown, you're rewarded with a certificate to commemorate your feat, available from the Visitor Centre.

The karri is the tallest tree species in Western Australia and the third tallest in the world. It can grow up to 90 metres in height over a period of about 100 years.

There are several well signposted bush walking trails in the area that take you into the forest. They include the famous Bibbulmun Track and a 10-kilometre loop walk.

Watch out for rare birds in the forest including red-tailed black cockatoos.

The Gloucester Tree is part of a trilogy of Karri tree towers which are open to the public. The others include the Bicentennial Tree and the Diamond Tree.

The Gloucester Tree was named after the Duke of Gloucester who visited in 1946.

A short drive from Pemberton which is three hours south of Perth.

The Gloucester Tree climb is currently closed for maintenance. For the latest information on opening please visit the Parks and Wildlife Service website: www.exploreparks.dbca.wa.gov.au/site/gloucester-tree.
