Good. Now I have all the data I need. Here’s the description:

Tucked into the remote northernmost reaches of New Hampshire’s Coös County, Coleman State Park offers 1,573 acres of unspoiled wilderness along the shores of Little Diamond Pond. This is New Hampshire at its quietest and most rugged, a place where moose sightings are common and the night sky puts on a show that southern New England visitors rarely get to experience.

The park sits near the Canadian border in Stewartstown, surrounded by dense boreal forest that feels worlds away from the busy White Mountains corridor to the south. Diamond Pond Road winds through the backcountry to reach it, and that remoteness is precisely the point. Anglers come for the excellent brook trout fishing in Little Diamond Pond and the nearby Diamond River system, where cold, clear waters support healthy native populations. Canoes and kayaks work well on the pond, though motorboats are limited to keep things peaceful.

The campground provides a solid base for exploring the area, with wooded tent and RV sites set among spruce and fir trees. Facilities are straightforward but well-maintained, fitting the park’s backcountry character. Hiking trails loop through mixed forest where fall foliage arrives early, usually peaking in late September, painting the hillsides in brilliant oranges and reds ahead of the rest of the state.

Summer and early fall are the prime seasons, with July and August bringing warm days and cool evenings ideal for campfire nights. Visitors should come prepared for variable weather, limited cell service, and the kind of genuine solitude that’s increasingly hard to find in New England. Coleman rewards those willing to make the drive.
