Pisgah State Park

Near Keene in New Hampshire, Pisgah State Park offers a straightforward outdoor swim on Kilburn Pond. This is not a beach with a parking lot and a snack bar. It's a living, breathing piece of old-growth wilderness where the water is cool, the crowds are thin, and the loudest sound is usually a loon or the wind moving through the canopy overhead. The pond is part of a complete watershed entirely contained within the park. Meaning the water flowing into it passes through nothing but wild, undeveloped land. You'll approach along a 0.7-mile trail that winds through dappled forest light, crossing a rustic log footbridge that feels like something from a storybook. The uneven terrain demands your attention, but the payoff is immediate: the pond opens up before you, edged in granite boulders and fringed with forest reflections that seem almost too perfect to be real. In fall, those reflections turn amber and crimson. In spring, wildflowers push up along the trail margins. In summer, the whole scene hums with insects and birdsong. The kind of cool that makes a July afternoon feel like a gift. Large, flat rocks line stretches of the shoreline, giving swimmers natural platforms to sun themselves, leap from, or simply sit and dangle their feet before slipping in. The pond's natural bottom and undeveloped edges mean you're entering the water on nature's terms, which is precisely the appeal. Wildlife sightings are common. Keep your eyes open for herons, turtles, and the occasional osprey working the surface. Facilities are unknown, so bring everything you need: water, snacks, a towel, and sturdy footwear for the hike in. The trail involves uneven terrain and a log footbridge crossing, earning it a moderate difficulty rating. It's accessible to most healthy adults and older children but may challenge young toddlers or those with limited mobility. There is no fee to enter Pisgah State Park. Treat Pisgah State Park as a wild swim: no lifeguard, variable depth, and rules that can change by season.

Pisgah State Park works well as a day trip from Keene or Winchester. Stock up in town, then head to the water with food, water, and sun protection. Pair the swim with a stop at The Ledges (about 5.8 mi away) or browse more New Hampshire lake spots in our directory. For the full list in New Hampshire, see our state directory.
