Trail Conditions
Notes
Up Guinea Pond Trail, left on Black Mtn Pond Trail, up and down Algonquin Trail, and a short road walk back to the car. This route is very gradual for the first four miles or so (to Black Mountain Pond). Then it gets your attention by climbing the ledges south of Black Mountain (1000 feet in 0.8 miles). As you climb, the views from the ledges get progressively better. I enjoyed lunch from one of the ledges just below the intersection with Algonquin Trail. From that intersection to Sandwich Dome, Algonquin Trail is a 1.7 mile ridge walk, mostly in the trees with minor ups and downs. Below the intersection with Black Mountain Pond Trail, Algonquin Trail is very steep and scrambly. It makes for a slow descent, but it is a lot of fun. (I learned after the hike that Algonquin is one of the electives on the T25 list.) After the steep bits, Algonquin trail is a more gradual descent to Sandwich Notch Rd. Obviously, most people climb Sandwich Dome from the north. If you are looking for a bigger challenge, I definitely recommend this route. It features a beautiful Black Mountain Pond, varied terrain, and countless views. Despite the reputation for being notoriously wet in the Guinea Pond and Black Mountain Pond areas, take plenty of water. I didn't find any water flowing fast enough to put through a filter.
