Mountain biking trails aren’t marked too well. A good ride with some challenges. Will definitely do it again.

I really enjoyed this trail. It’s difficult enough to be a challenge with some light rock climbing (nothing crazy) and steep hikes, but still moderate enough to be a nice leisure hike as well. Plenty of nice look out spots by the tower and the lake was a nice treat. There’s tons of trails connecting as well so it’s super easy to customize your hike if you don’t want to do the full course of one specific trail. Would totally hike it again.

Awesome little hike - some challenging scrum and bouldering but nothing too nuts

Great hike. Brought my dog and let her off leash for parts of the trail. Nobody seemed to care.

Nice trails but not very easily marked. The app was helpful for seeing where the various paths connected.

Nice wooded trail with a few views of the reservoir and other ponds. View from the top was ok but mostly trees. Trail wasn't consistently marked, had to check the map regularly. Took me about 1.5 hrs.

Great time, walking the dog while enjoying the beautiful Fells during a nice, warm fall day. Hard to beat.

Very close to the city, family and pet friendly walks.

The trail was nice, the view of the sunset from it was breathtaking, a bit disappointed with the cave, thought it would be bigger, but overall it was a pretty interesting and relaxing trail. I'd like to revisit it.

Great experience in terms of photography. Also, the perfect terrain to walk to the beat of your music while exploring through the woods.

It was a fun hike. Met some nice people. Climbed Wright's Tower and took in the 360 degree vista of fall foliage and bumper to bumper traffic on 93.

I went back again and followed other trails heading north and further west along the lower reservoir. Too bad a local park/MWRA authority came by to clear folks out from the trail around the reservoir. It was a beautiful day and the dirt road was a nice respite from some of the hillier and rockier sections.

Very pleasing to be so close to the city but to be Able to get away!

Great 2 hour loop through most of the elevated points in the southern part of the Fells. Varied terrain and many rock scrambles up to great views of the reservation and the surrounding communities.
