This section of the AT (Carlo Col to Old Speck Mountain) is one of the most fun, challenging, rewarding and beautiful hikes I've been on in years. It rivals several hikes I've done in Colorado and Alaska. The ridge from Goose Eye to the South Peak gives incredible views to the West, with Adams and Washington looming in the distance. Mahoosuc Notch was a mile of technical scrambles over massive car to garage size boulders. And then Old Speck Mountain has a lookout tower on which you are rewarded with a spectacular 360 view for a good 20-30 miles. I can't wait to get back up there!
