Very good place near Boston for a 3 hour hike, especially when you walk around the lakes closer to the water. The only issue was that we had to check with map literally every 5 minutes as this trail is a mix of various other trails and routes. This was a little inconvenient and did not allow us to completely relax and enjoy the hike. We even got lost a couple of times, so pay attention to the trail that you follow. . Honestly I have no idea how people can hike here without a map or app with tracker, it’s very easy to get lost:)

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

Good place for hiking, but it’s never considered as Hard, Moderate at most.

Well marked trails. Not really hiking yet not really a simple flat walk. I would say it’s on the high end of easy to the very low end of moderate. It was very nice but I have similar walks closer to my home so I personally wouldn’t go out of my way to go again.

This is a great trail for running as it varies in difficulty as you go. There are some flat, easy spots but there are also some areas with rocks and roots that you have to dodge as you run up and downhill. Highly recommended!

A great day hike! parked at Upper Sheepfold. prepare for a good 3 to 3.5 hour hike.

great trail!

Some trails could be better marked, but overall very good.

Sound autumn view

well marked, great for running & mountain biking.

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.

A nice stroll in a little wood. Nothing amazing but easy to reach from boston. Which trail you take doesn't matter much, and it's easy to "get lost" here

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.

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!!

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.

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.

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.
