The reserve is only open to the public six weekends a year, and I'm afraid if you want to go in 2011, you'll have to go next weekend (10-11 September 2011). There's a range of walks from an easy 1km loop to a longer and harder 10km loop. Each of them is an opportunity to see a huge range of flowers, views across Brooklyn and the Hawkesbury River, and see a little history of the early European settlement. Peat's Crater is home to a rare osage orange hedge, which keeps people busy trying to control it's spread into the neighbouring bushland. The reserve was made all the better for me because I had good company, but I'm sure anyone would love this place :)
