In addition to Mount Blackheath, there are a number of other sites flown occasionally by the Blue Mountains Soaring Club.
Sofala Site Guide
Sofala is a private-land takeoff with a public landing zone, about 10km East of Sofala itself. This site has been flown very rarely by club members in the past years.
Mt Rankin Site Guide
Mount Rankin is a beautiful site located just outside of Bathurst on private property with some good cross-country options.
