Walpole-Nornalup National Park is within the Walpole Wilderness Area near Denmark. It is nearly 20,000 hectares of towering karri and tingle forests to coastal heath with little evidence of human activity. The rugged coastline, peaceful inlets and rivers are a major feature of the park's beauty, probably best known for the huge buttressed red tingle trees, unique to the Denmark area.

The Tree Top Walk is one of the area's most popular tourist destinations. A 38 meter high walkway meanders through the tree tops, all ages can view the canopy of the magnificent tingle forest and get a different perspective on the shapes, sounds and movement of the forest.

Circular Pool is located on the FranklandRiver approximately 7km (as the crowflies) north east of Walpole within the Walpole Nornalup National Park.
