Samuel A. Tamposi Water Supply Reserve (SATWaSR), Barrington, NH

There are lots of great trails to explore at SATWaSR. For this review, we will be sharing details on our 2 favorite hikes – to the power lines and back, and up Mt. Ripley. Check out their complete trail listings .

Please note that dogs are allowed off leash on these trails. Because of this, we recommend visiting during a weekday if your dog needs additional space. On weekends, if there are no or few cars in the parking lot, then traffic on the trail is usually very light.

The trail to the power lines is the main trail aka Tibbetts Rd. (where the main road turns into a class 6 road). This is a nice trail because it is wider and great for parallel walking dogs. It is a pretty walk in any season. There are also many trails off of this main route to explore.

Eventually, you will come to the beaver pond at around 1.8 miles from the gate. In winter, when the ice is solid, you can walk across and connect with the trail on the other side. Other times of the year, and to be safe, take the detour trail to the right, across the bridge over Bergeron Brook, and around the pond to the other side. Eventually, you will reach the open area at the power lines. Just beyond this area is an entrance off of Route 4. From here, turn around and enjoy the walk back to the parking lot.

For a different experience, take a left onto Highland Trail Loop, which is off the main trail. Trails are well marked. This trail is narrower and gradually climbs a small hill to the top of Mt. Ripley. At the top, read about Ripley (2005-2019), Barrington’s most famous dog who is the first known individual to conquer the summit.

Both trails traverse wet areas so choose your footwear accordingly.
