The cache is NOT at the posted coordinates. That is the location of the Hermit's Cave. You are welcome to go inside if you like and check it out. The Hermitage Mansion may also be open occasionally for touring.
In order to find the location of the geocache you will need to complete the Adventure Lab of the same name; Hermits of the Wissahickon
Please note there is no need to bushwhack for any of the adventure locations. If you find yourself off trail please reconsider and find an already established path so the natural beauty of the area does not get destroyed.
