Boating, Kayaking and Swimming

Lake Whitingham (Harriman'Reservoir)

Harriman Reservoir, also known as Lake Whitingham, is the largest body of water completely within Vermont’s borders. It was built by New England Power Company as part of their hydro-electric system and finished in 1923. Over eight miles long, with 28 miles of winding coastline, the lake provides hours of relaxing fun for swimmers, boaters and fishermen alike.


For swimming, the lake can be accessed at a number of points, among them, Wards Cove, Castle Hill picnic area, and Mountain Mills.


To get to Wards Cove from Wilmington, take Route 100 south. About one mile past the junctions of Routes 100 and 9 you will see a sign on the right for Flames Stables. Turn right onto the dirt road and follow it to the lake. Picnic tables are available.


For Castle Hill and Mountain Mills access, head to downtown Wilmington. At the light, go straight .3 miles on S Main Street. Continue up Castle Hill and turn right on Fairview Avenue, following the signs to the boat launch. Continue on until the pavement changes to a dirt road. Castle Hill picnic area is on the right, 1/4 mile after the road turns to dirt. Continue on to the end of the road for the Mountain Mills access area.

Somerset Reservoir

Somerset Reservoir is a large lake in southern Vermont that is nestled deep within the Green Mountain National Forest. The lake is actually a dammed section of the Deerfield River, and is roughly 6.5 miles long and covers 1568 acres. The shoreline is totally undeveloped, but there is a small boat launch and some picnic tables. The lake sits at 2,000 feet above sea level, so it’s a great place to cool off in the summer. The winter snows don’t melt here until May. It’s an excellent spot to bring a small fishing boat, canoe, or kayak.

Paddling around Somerset on a rare calm day is an amazing experience. You may see loons, ducks, or mergansers, and moose, deer, and black bears are also common along the shore. Summer weekends can be busy, but because the lake is so big, you will always find solitude on the water or hiking trails.

There is an extensive trail network in Green Mountain National Forest, and the East Branch Trail runs along the east side of Somerset Reservoir, all the way to Grout Pond, which is just north of Somerset. Mountain bikers use the trail, and it is part of the Catamount cross-country ski trail that runs the length of Vermont.

The lake remains an unspoiled treasure in Vermont, perhaps because you must travel 10 miles on a dirt road to get there. Whatever the reason, this beautiful Vermont lake is definitely worth a visit.


Dorset Quarry

Calling all adventure seekers! If you’re reveling in all of the unique experiences that the Green Mountains have to offer, don’t miss out on a dive into the deep waters of the Dorset Quarry. The swimming area, within the remnants of a formerly operational marble quarry, allows for thrilling dives off the smooth stone—reaching up to 30 feet at some spots.

The faint of heart can enjoy less daunting launches, however, or utilize the ladders that extend into the water. The unique destination does attract crowds, and because the area is privately owned parking can become a challenge on busier days. Be sure to arrive early and ready to swim, and plan a midweek visit if possible. Don’t forget your GoPro to capture the daring descent—if you’re brave enough to take the leap.
