http://tinyurl.com/Peak-CharlesFantastic place to explore. There is a 'day use' area near the base of Peak Charles as well as the campground.
Early morning is the best time to trek up the 650m orange granite peak which was described to us as a scramble, rather than a hike. A few 8 - 12 yr olds were totally exhausted by the time they got back but were quite proud of the cairn they made up top. Their previously very energetic mum was certainly looking forward to a rest!
Also in the park are other granite outcrops, eg Mt Eleanora, a kaleidoscope of plants and numerous animals such as emus. We spent 3 days exploring here before moving on.
