Nepean lookout is a natural viewpoint above Fairlight Gorge and the Nepean River in the Glenbrook area. The river bends below steep, tree-lined sandstone walls, with the lower Blue Mountains beyond. It is a worthwhile pause on the Glenbrook drive: the track from the car park is short and easy, but the lookout itself is unfenced. Keep children close and stay well back from the edge. From the viewing area, try to fit both the river and the gorge walls in one frame; that shows the landscape the river has carved.
