I came across this article today in the Washington Post about a 2.5 mile-long, wheelchair accessible hiking path in NH. Located at Crotched Mountain Rehabilitation Center, in southwestern NH, it opens to the public this Friday. According to the article, there is a variety of terrain, broken up with bridges, boardwalks, platforms, and viewpoints, and the trail ascends a total of 200 feet and reaches an 8% grade.
I don't see myself getting to NH anytime soon, but perhaps a local can check it out and let us know what it is like.
Thought I would share for those who are interested.
