Updated May 11, 2026

If you've ever tried to plan hiking in Ashland State Park, you know how quickly the options can feel overwhelming. With so many trails, it's tough to tell which routes are genuinely worth your time and which are just filler. That's where we come in: our komoot community has mapped, walked, and reviewed these trails, so we've curated a shortlist of the best, saving you the guesswork.

Hiking in Ashland State Park feels like stepping into a classic New England landscape, centered around the picturesque Ashland Reservoir. You'll find yourself winding through lush, forested terrain, past old stone walls, and along the water's edge. While many routes are easy and accessible year-round, offering gentle paths, there are also options with a bit more elevation if you're looking for a challenge.

If you only do one route, make it the popular Ashland Reservoir Dam – Ashland Reservoir loop from Ashland State Park, a 4.4 miles (7.0 km) moderate trail that offers continuous reservoir views and a real sense of the park's character. For a slightly shorter, easy option that still delivers on charm, we love the Cowassock Woods loop from Ashland, at 2.7 miles (4.4 km), perfect for a quick escape into dense woodlands.

The Ashland Reservoir Trail offers a delightful escape into nature, tracing a 4.0-mile (6.4 km) loop around the picturesque 157-acre Ashland Reservoir. You'll find yourself immersed in a landscape of tall pine trees, undeveloped shorelines, and historical elements like old stone walls, with continuous water views.

The route is dog-friendly, perfect for family friendly hikes, and typically takes about 1 hour and 38 minutes to complete. Be aware that some sections can be muddy or flooded, so appropriate footwear is recommended, and carrying a map is a good idea as signage can be inconsistent.

This trail is a gem within Ashland State Park, offering more than just hiking; the reservoir is stocked with trout for fishing, and the park provides opportunities for boating and swimming. The Ashland Dam, a key landmark, offers excellent panoramic views and is part of Boston's historic late 19th-century waterworks.

The finish line painted on the street is located not far from the Boston Public Library. Also nearby is the site of the marathon bombing on April 15, 2013.
