BPX Trip – BPX 3-Day: Colorado Trail - Segment 6 from the Kenosha Pass West TH

This trip is for BPX members. Feel and see the coming of fall, while enjoying the longest segment of the Colorado Trail. We'll hike three days, averaging 10 miles or so a day. Available camp areas along the way and a wonderful trail make for a fantastic way to spend three days in the embrace of Mother Nature, Always a good thing. IMO, of course.
