Based on my knowledge of Wellington State Park, here’s the description:

Wellington State Park sits along the western shore of Newfound Lake in Bristol, New Hampshire, home to the largest freshwater swimming beach in the state park system. Spanning 204 acres in Grafton County, the park draws families, swimmers, and day-trippers who come for the remarkably clear waters that Newfound Lake is famous for — often ranked among the cleanest lakes in the country.

The sandy beach stretches over half a mile and slopes gently into the water, making it ideal for young children and casual swimmers alike. Beyond the shoreline, wooded picnic areas with grills and tables sit tucked beneath towering pines, offering shade on hot summer days. A network of hiking trails winds through the surrounding forest, including paths that climb to rocky overlooks with views of the lake and the surrounding foothills of the White Mountains.

Visitors will find a bathhouse with changing rooms, a small concession area, and ample parking, though the lot fills early on peak summer weekends — arriving before 10 AM is strongly recommended on Saturdays in July and August. The park does not offer camping, but nearby options at Newfound Lake and in the White Mountain National Forest are plentiful.

The best time to visit is mid-June through early September, when the beach is staffed with lifeguards and the lake water reaches its warmest. Fall visitors are rewarded with stunning foliage reflecting off the lake’s surface, though beach facilities close after Labor Day. Wellington is a day-use park with a per-person entrance fee — a worthy trade for one of New Hampshire’s finest swimming spots.
