These four Karri Trees growing in "Indian File" are the sole survivors of 10,000 germinating seeds in the ash bed of an old karri. At 220 years old, they began life just after the French Revolution and at the time when Captain Cook made his first sighting of Australia.

A very pretty swimming and picnic area on the delightful Donnelly River with barbecues, shade, walk trails and toilets provided. A walk trail links the pool and nearby historical One Tree Bridge and the Four Aces. In season, fish the river for Leaping Rainbow Trout or Marron. 

Tall, temperate forest surrounds Manjimup which include the majestic Karri and Jarrah trees. Wildflowers are abundant in Spring all through the forest. Australian wildlife also inhabits the forest including Western Rosellas, Lorikeets, Port Lincoln Parrots as well as Possums and Kangaroos.

At the top of this 51 metre Karri Tree and about 10 kilometres from Manjimup is the only wooden tree-top tower in the world. It is still used as an integral part of the fire management of the area. Climbing of the tree is permitted for the brave and a forest adventure trail also starts here.
