You can, if you choose, walk the 21-km Mungo Track to Mungo Brush, a popular camping and picnic spot on the southern shore of The Broadwater, the southernmost of the three Myall Lakes where the bird life is prolific. It starts from a signposted spot 750 m along the road from the information board. The former leads over a series of vast, denuded and impressive sand dunes, past an ancient Aboriginal midden to an absolutely beautiful and unspoiled bit of coastline looking out over Broughton Island. Both Broughton Island and the waters off Little Gibber are noted diving spots. The former is a good spot for fishing, bushwalking and relaxing.
Camping is permitted and there is a toilet, an emergency radio and some drinking water.
However, access from Tea Gardens is only in the peak period and then is not guaranteed. Nelson Bay are a more certain bet but only in summer. Otherwise you must make your own way. Little Broughton Island is an important breeding location for a number of birds. The Wildflower Walk, and the park in general, are best between August and October.
