Dismal Swamp is in the top portion of the Tarkine Region. It is a large, swampy forest which is located in a sink-hole. The tops of the trees are at roughly the normal ground level. There is a very large, covered slide which is the quick(very quick) way to the bottom. Some times you just have to conquer your fears!!
Oh my- not sure I'd weather that well with a bad hip! But then it would probably be worth since going down the equivalent in stairs would take hours!! Good for you in having done it- and photographed it too!
