The Southern Ridges is an area of different parks and walks starting from Mount Faber and continuing to the Hort Park. The cache is located at the end of the Forest Walk, which could be a nice end of a walk from Henderson Wave all the way down to the Gillman Baracks. As a highlight the Alexandra Arch is crossing Alexandra Road and especially at night it is a very nice view.
The container will hold a challenge for you. You can only log the cache if you mastered it. No fotologs allowed. You won't need any force, so be careful with the cache. Please put everything in place as it was before.
The challenge is back and I hope it will hold now. Please be gentle. If you can not solve it, leave it there, check for options at home and come back. You will be even more satisfied.
Update 20.06.2016: The puzzle is not holding at the moment, so I change the name and reduce the Difficulty to reflect it properly. I will leave the cache at its place, but it is not fully working. Very sad.
