Mt. Prospect Trail is located within the Mt. Greylock State Reservation and offers two scenic vistas overlooking Williamstown, MA. From Money Brook Trail: Beautiful, easy walk along Money Brook approximately 1.9mi then rocky uphill to Mt. Prospect Trail where the terrain becomes rocky, steep and strenuous. Approximately 1mi to first vista and an additional mile to second vista. From the Appalachian Trail: Flat then gradual climb approx. 0.5mi to first scenic vista with relatively unobstructed terrain. Follow the Mt. Prospect Trail approximately 1.0mi to the second vista.

Made it to where the AT splits off before having to turn back because of time. Beautiful ridgeline during the ascent, and great views to the west once the climb is over. A bit of ice in the steeper sections but nothing microspikes couldn't handle. Lot at the AT trailhead holds about ten cars.

Started out from the trailhead on Patterson Road, the AT goes steeply up for the first mile or so, then moderates as you go higher on the ridge. Mt prospect trail deviates to the right passing a couple of beautiful open spots where the views toward the Taconics and Williamstown open up.There is a large Cairn at the summit, then the trail starts to drop down. You do get views of the Greylock summit in the distance. We went on a cold day and it was brisk along the ridge as the air speeds up as it goes over the mountain, but the views were beautiful and very different from most hikes on Greylock that offer views toward the Adams side mostly. We were out about 3 hours which makes a nice half-day hike.

Accessed this trail via the Money Brook Trail as part of a large loop I had planned for that day's hike. It was rated as aggressive on the Greylock website but it was more aggressive than I had planned or thought it would be. The beginning is moderate and deceiving as the climb grows steeper and steeper and is very rocky. After we passed the first vista around mile 1 the trail began to level out before reaching the second vista at the junction with the Appalachian Trail. The first vista was obstructed. The second offered great views. Wouldn't do it again via Money Brook though.
