Lake Tarleton State Park

Lake Tarleton State Park

New Hampshire (Grafton County)

Tucked into the wooded hills of Grafton County, Lake Tarleton State Park offers a quiet retreat centered on its namesake glacial lake. At just 48 acres, this compact park punches above its weight — the lake itself stretches far beyond the park boundaries, giving visitors access to surprisingly expansive water without the crowds that flock to better-known New Hampshire destinations.

The real draw here is the lake. Clear, calm, and ringed by mixed hardwood and conifer forest, Lake Tarleton is ideal for kayaking, canoeing, and swimming from the small sandy beach. Anglers will find smallmouth bass, perch, and pickerel worth pursuing, particularly in the early morning hours when the water is glass-still. A boat launch provides easy access, though motorized craft should expect size restrictions that keep the lake peaceful.

On land, hiking trails wind through the surrounding forest and connect to the nearby Appalachian Trail corridor, making this a solid base for day hikes with longer-range options. Birdwatchers will appreciate the loon population that nests on the lake through summer.

The park shines brightest from late June through September, when the water is warm enough for swimming and the long days maximize time on the lake. Fall brings spectacular foliage reflections off the water, drawing photographers and leaf-peepers alike.

Lake Tarleton State Park won’t overwhelm you with amenities or programmed activities. What it will do is give you a genuine, unhurried slice of New Hampshire lake country — exactly the kind of place you came north to find.
