The Heathlands Walk Trail starts at a small carpark along Preston Beach Road, just off the Forrest Highway and follows a wide track that is used for maintenance vehicles. It is signed to be walked in a clockwise direction.
The first part of the trail is fairly flat, but before long it starts climbing gently over the limestone ridge. There is a short rock side trail to a lookout, with views out over Lake Preston and the ocean beyond.
The trail continues towards the lake. At the western most point there is another side track that takes you through a tunnel of trees to the water's edge.
Returning from Lake Preston the trail meanders up and down along the ridge and at times you can see over the surrounding countryside. During the springtime this walk provides walkers with a wide array of wildflowers.
