Brian Creek Monsoon Forest, in the Mary River National Park which is an hour's drive from Darwin, is a short walk through a pocket of rainforest where you will notice the contrast between the wildlife here and the surrounding woodlands.
These pockets are significant examples of remnant vegetation communities that are surrounded by dry lowland woodland savannah. The walk is relatively easy, allow 45 minutes round trip, and a picnic table at the start of the track provides a quiet spot to rest and enjoy the surrounds.
