Welcome to The Cohos Trail …

Adam Wilcox proposed the route:

This has been a staple training route of mine for years that I've done variations of numerous times. It's a logical way to link up four 4,000 foot peaks with one car, clocks in at about 17 miles and 5,520' feet of gain, and has a good variety of trails; steep rocky climbs, flowy singletrack, and viewpoints. I have enough experience here that I'd like to think I picked the most sensible and aesthetic variation.

Backpacker Magazine called Maine's Bigelow Traverse one of "America's Hardest Dayhikes", saying "You’ll be tempted to run this northbound traverse of the AT from ME 27/16-not because you’re feeling jaunty, but to escape the Maine woods’ infamous black flies. But the relentlessly steep and rocky trail along long, forested ridges discourages any such fantasies.
