good little walk through the woods, but nothing too exciting. for mountain folk like us it was a bit mundane. No real hills or anything fun to climb. very easy

Many different trails. Followed skyline trail. Plenty of climbs. Good workout. Definitely recommend to bring good trail shoes or hiking boots, water. Trails are well marked.

Did this by accident because the rock circuit is poorly marked. Decent run.

pretty nice hike, paths aren't fully marked and lots of unleashed dogs.

By far my favorite place to go on my days off. I actually really enjoy how busy it can get - I do a full loop each time and cross over between several trails. On a weekend, I'd run into someone else maybe every 20 minutes... But by far my favorite trail to do from start to finish is the skyline trail. I would rate the skyline trail as moderate, but everything else is easy. It's very dog friendly. We always start at Sheepfold and go from there. Once you know the trails, it's easy to cut through - they're decently marked. I'm a relatively fit person but I like to take slow hikes with my dogs - the full loop and a little more takes us about 1.5 hours. I love it!!

I’m new to backpacking and I am in training for bigger ,longer hikes. This trail is serving me well. It has many ascents and descents as well as ledge. Well marked . It is taking me between 4-41/2 hours depending on size of my pack.

Fairly easy trail, conveniently located. Long Pond is nice, but there aren’t many other interesting features.

Not too hard, good views of Boston from ledges, there is a stone tower that is occasionally open, which provides views of the Fells and other nearby landmarks.

This trail was a fun walk. The difficulty was easy to moderate at most. We found the trail markings to be insufficient, especially at some intersections. Surprisingly long given the location. Will likely hike it again in a different season.

Lots of variety. Beautiful trail without too much traffic on a Saturday.

Parking lot at (42.4496220,-71.1257951). Nice, short walk.

I’ve gone snowshoeing along this route, there are multiple solid rock climbing spots. The west side of the Fells is too crowded but this side is awesome

Great winter walk close to the city. Helps scratch the hiking itch.

I want to hit this trail for a winter hike. Would I be ok with just spikes? Or are snowshoes needed?

Great morning hike. Beautiful views of reservoirs. Keep an eye out to follow sineage!

Really nice hike and running trail, I’m a newbie and it was doable.

Principally a pine forest on shallow soil over glacial stoney rubble. Mostly ~50 year old tree. Just few older. The trail rounds the small shallow lake mostly above. Petty views of that water. At the highest point a short detour to the west reveals an excellent vista. Pine forests, in my opinion, are a bit dull. The Fells are popular, this trail is less crowded than others.

Decent walk around the reservoir. It was a bit more challenging than I expected it to be. The trails were a bit hard to find at times but course correction wasn't difficult to get back on track. Parking is limited so get there early.

This is my 4th time here, very nice place with different views. Rocky and lake .
It took me 6 hrs slow- medium walk. Fresh air .
1,5 liter of water .
Not too hard really, any fit person can do it. And what is nice here if you get tired from one trail you easily can switch to an easy one like the blue trail.
Enjoy and stay fit and healthy this is the ultimate wealth.

Great train, light traffic, can be done in parts, if you tire out just take a fire road close to it.

Great and local. Wish I knew about it when I was younger.

Great Trail, every kind of terrain, lot of views

Great trail! Wish the signage was easier to read

Great easy hike, so green, so many cute dogs!

Great trail! Very well marked.

Really nice trails with lots of options! Made our way to Spot Lake which was gorgeous.

Hiked this today- great hike with some parts being more access-road-like and others being wooded trails. Part of the trail is the Rock Circuit trail which can be lots of rock climbing up/down which was difficult for a beginner like me, but a good challenge.

Nice views of reservoirs but way too crowded. Parking lot mobbed. Could have a long wait. Granted it was a nice Sunday in the summer. Would only come back on a weekday
