Great loop with the dogs. Plenty of parking in the lot and on the street. Views are great on the two summits to see 270' to Boston, Mt Wachusett and Pack Monadnock. I wouldn't necessarily recommend the steep rocky direct descent as it ends at the street quite a ways from the lot. There might be trails that bring you back to the main trail from there, though. We did the 3 mile loop and it was just right for 1 1/2 hrs with two dogs. Saw several groups from families to teens to a runner and lots of dogs.
Watch the rocks! Some places on the trail are easier to run than others! I would say my 'trail run' on this mountain is more of a vigorous and/or very fast-paced hike. I usually finish the full loop in about 45 mins, and 'run' this trail at least once a week. The view is awesome. First time i ran this trail it was a little bit confusing. Make sure you check your map before you go. This used to be a skiing mountain and it shows through the trails. Altogether love this mountain and love to run it.
Beautiful quick hike! Hiked up and down the wapack from 119. Took about 2 hrs. Great views for a small mountain. Saw a couple of red hawks at the summit, flying so close I could see their eyes! Saw 7 other hikers total on the trail, a couple of milk snakes, and many birds.
It depends on which loop you take. We took the larger loop going up, and the shorter loop coming down. The short loop is definitely steeper for a more advanced hike. The view at the top was wonderful it was clear enough we saw Boston skyline. Good trail
