Most of it is just a line and not a loop, so walk and turn around. But its a great little hike along the Shawsheen River, at least if its not bug season. Lots of marshy land would make it an extra buggy destination some times of the year

A wonderful natural preserve, this is worth a trip.

Nice trail by the side of the Shawsheen River

A peaceful and easy stroll through the reservation is great way to escape for a little while and reset. Find a bit of nature betwixt the Shawsheen River and train tracks, catch a glimpse of local wildlife, or a boater on the river. Stroll through the meadow, sit and admire nature.

Great atmosphere. The place has well designed boardwalks. It has many roots on lower paths so it is smart to pay attention.

Super convenient and well-maintained.

Short but very nice hike

Great place to get away from everyday life and get into the woods see some wildlife not to far from home. Very peaceful here my dogs also love it

Great place to walk the trails, great place to bring your dogs for a walk & to see more wildlife I love walking here

Ballarvales central park. Ok, maybe that is a bit of an exaggeration, but it is a nice place to go for a nature walk. Trail is easy to follow, with minor deviations here and there. Not much straining on inclines - trail is nearly flat all the time. Some tree roots and stumps scattered around the path, perhaps positioned by the wood fairies or nymphs for their amusement (at your expense). There is a 88.23% chance you will run into someone else, 76.07% chance they will have dogs, and 51.23% chance the dogs will be running around free (previous stats provided by a cluster of thousands of AWS, Microsoft Azure and Google cloud nodes running non - stop analysis of trail probability models for 2 months. Either that, or the stats were made up to enhance the review). So you most likely wont be alone the whole walk (not counting the occasional fairy or nymph you may think you caught a glimpse of from the corner of your eye). Still; a good place to commune with nature and ponder mysteries inloving chickens and eggs, or chickens crossing streets - all without traveling outside the Andover area and staying within the known dimensions (mostly)

Trails were not marked at all and were really hard to follow. Some appeared to not be maintained. There were a few overgrown spots.

Well marked trails, easy walking, and plenty of birds and other wildlife.

Very nice reservation!
