So I am looking to plan a solo trip some time in the next 2/3 months, that is a 4-5 day minimum, and very isolated. Last year I did the Northville-Lake Placid trial which was awesome. I would like to find something even more isolated, difficult, and cool. I do a yearly long trip elsewhere in the country, this one I would like to stay within a days drive of NYC.
Right now I am thinking about the 100 mile wilderness stretch of the Appalachian Trail. I am somewhat concerned about even that long stretch of the AT being crowded though. What other options are out there?
