I spent three days camping on own at Dunn Swamp near Rylstone, NSW.
The swamp is really a small dam. The water backs up between a narrow gorge of sandstone rocks that look pagoda-like.
There are two good kayak trips - up or down river. The up river trip becomes very narrow and in parts is difficult to make headway due to the reeds and overhanging brush. The kayak down river leads past tall reed areas and tall sandstone cliffs. The early morning sun reflects the golden hue of freshly broken slabs of sandstone plus the morning mist and stillness leads to mirror like reflections. The trip ends in the buoys protecting watercraft from venturing to close to the dam edge. It is a long way to the bottom of the dam wall.
There are two main walks with some side tracks. Both follow the river to a degree. The upriver walk passes through swampy areas and very dry bush. It eventually leads to a gauging station for the river. Side tracks lead to a picnic area and various rock formations. the second walk leads down river and passes through amazing rock formations and steep climbs to the top of the cliffs that line the river in parts. The track leads to the dam (weir) and thee long cave, which is really a long overhang of rock that can be walked under. At an earlier stage of the track, their is a side track to pagoda hill which is a fun steep rock scramble. the views at the top are excellent.
The camping was very quiet and the night silent. One needs to bring water and there are toilets only provided.
While here i saw heaps of wildlife - various birds, insects, goannas, kangaroos, possums, spiders and turtles.
The most noticeable aspect of the place is the sense of quietness and peacefulness.
