I have been hiking the fella since I was super young - started doing this hike with my dad on Saturday mornings in the summer. Nothing to strenuous but definitely lots of beautiful forest to see!

not well marked and tons of bugs. the woods are very pretty though.

Nice hike in the city. Very dog friendly although did see a few snakes. Parts near the highway quite loud. Few spots the Alltrails map seems to be off but easy enough to figure out where to go. Lots of intersecting paths so if you're intent on following the loop I'd have a map open most of the way. Easy, definitely low end of moderate. Saw a couple bikers and a few other hikers but otherwise had it to ourselves late morning/early Sunday afternoon. Few bugs but not a problem. 6/9/19

Great trail that can be modified many times over with all the different trails. The markings could get confusing so definitely check in with AllTrails to ensure you’re on the path you want. I did not bike but did see the conditions were a bit muddy for the bike path.

Great with a dog!

Went here with a 9 and 3 year old hoping for an easy path- there were too many places that the 3 year could not handle. Great trail, had to stop 1/4 of the way and turn back bc kids got tired. Will definitely come back, sans kids. Very easy trail if you hike like we do. Many of the paths are overgrown with thorns!! Many of the paths are poorly marked and could be quite confusing if you don’t pay attention. Gorgeous! Highly recommend.

Would have probably been more fun going clockwise, but great trails. Easy to feel lost in nature right outside a city.

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.

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.

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

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

Great Trail, every kind of terrain, lot of views

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

great hiking! All levels. skyline trail is the best

Did a trail run on the reservoir loop. Had a really good time. it's a decent distance, technical enough to keep you entertained and the terrain is not too uneven that it gets uncomfortable running. The trail was well marked with orange paint and I had no trouble staying on track. I will definitely do it again.

Beautiful area to hike, run, bike, and play. Just be careful if you're on a time crunch- the Skyline trail tends to start and stop quite often and you can easily get off track. I wound up going in circles for about an hour and had a flight to catch! Another tip: arrive early. By 11:15 there were people lined up looking for a place to park.

Solid biking for Eastern MA. some really technical and tight single track but mainly large open fire roads. There is an old paved soapbox derby track that is fun to fly down. Really only gets busy on weekends. Slightly heavier traffic after work hours. Please don't ride in spring. The soft earth can't take the punishment.
