Have you been to Tutka Bay?  It is literally the wilderness.  There are no roads.  You have to take a water-taxi there (unless you are fit enough to trek over mountains or kayak across Kachemak Bay), at which point you are likely to pull up to some rocky beach where you have to jump out of the boat (without a ramp) directly onto a small beach, (as there isn't really a dock).  The taxi will arrange to pick you up at a certain time, so if you miss it, you are really in trouble.  Due to time, money, demand, and safety amongst other reasons, one can't necessarily make all areas of the wilderness accessible to the handicapped, unfortunately.  But, for those that are dedicated to a lifetime of fitness, and are adept at the art of outdoor living and wilderness adventure, developments of trails in Tutka Bay are a pleasant reprieve from the overpopulated world around us.  For those who are physically unable to get on the trail, there are several tour boats that can also get someone up close.
