Bush and city walking especially in the Sutherland Shire and Sydney Harbour

Our group is mostly made up of people who are retired though we are still fit and active. About 8-10 people walk with us every first and third Tuesday of the month. Walks of 2-4 hours are often in the Sutherland Shire in National Parks though sometimes we go further afield into the Blue Mountains, down to Kiama, or around Sydney Harbour. We travel by both car and public transport. The walks are of different grades from easy to hard.
