The Long Mountain Trail at the Mount Holyoke Range State Park in Granby, MA, is a moderate 2 mile out-and-back hike from Mt Harris Rd up to the summit of Long Mountain.

Follow the M & M trail (white blazes) from the parking lot. The hike is uphill almost throughout the entire hike. Just before the last climb to the summit of Long Mountain, the trail climbs a steep set of stairs, which can be iced over during the winter or slippery after a rainfall, so watch your step.

The lookout is on the far end which leads on to the notch visitors center. The lookout is not cut out from the trees very well, so you get better views during the colder months when the leaves aren't on the trees.

Great trail. Moderately challenging with one amazing view at the summit. This hike is a great option if you want to avoid more crowded trails. I made it a loop, descending a more gradual way. The only downside to this trail is it has to be the buggiest spot in the whole Holyoke Range. Didn't matter that I was wearing 40% Deet.

Hiked Long Mountain from the Mt Harris Rd parking lot the day after Christmas 2017 with about 4 - 6 inches of snow. The trail was empty but we did pass one other person as we hiked back down the mountain. The last leg of the hike shoots up the side of Long Mountain with stairs that make this section a bit easier. Hiking in the winter can be slippery so ice spikes can be helpful. There are more views in the winter through the trees as well.
