I haven't been to Pitkin in years, but as I recall there is at least one good road from the south—probably from US 50 between Gunnison and Monarch Pass. It is a very small place with not much going on. Pop. in 2010 was 66, 124 in 2000. Any business would probably be seasonal and a hobby rather than much of an income producer.
It is not in Pitkin County, but is in Gunnison County.
It is in national forest, so plenty of boondocking possibilities and maybe some primitive campgrounds.
I haven't look at the town website, but here it is: http://www.google.com/url?sa=t&rct=j...nlALXdTjiDqOZQ
