Best time to visit Coleman State Park
Late June through early September is the most reliable window, with warm days, cool nights, and the campground fully operational. July and August bring the warmest weather and the best paddling and fishing conditions on Little Diamond Pond, but blackflies and mosquitoes peak in June. Early September is a strong shoulder option for RV travelers who want cooler temperatures, fewer bugs, and the start of fall color across the North Country. Snow, mud season, and limited services make spring and late fall poor choices for RV travel here.

Things to do at Coleman State Park
- Paddle Little Diamond Pond EasyRV parking available
Little Diamond Pond is a small, quiet pond at the heart of Coleman State Park and is ideal for canoes, kayaks, and small non-motorized craft. The park has a launch area, and calm mornings are especially good for wildlife watching. RVers can unload paddlecraft close to the shoreline.
- Trout fishing EasyRV parking available
Little Diamond Pond and nearby Big Diamond Pond are stocked brook trout waters popular with fly and spin anglers. Shoreline access, a boat launch, and easy pond circumnavigation make this one of the top reasons to camp at Coleman. A New Hampshire fishing license is required.
- Hike park and Nash Stream area trails ModerateRV parking available
Short walking trails loop around Little Diamond Pond and connect to old woods roads through spruce-fir forest. More experienced hikers can drive a short distance to Nash Stream Forest and the Cohos Trail for longer routes. Trails are generally rustic with limited signage.
- Wildlife and moose watching EasyRV parking available
The Connecticut Lakes region around Coleman State Park is one of the best places in New Hampshire to see moose, especially at dawn and dusk along Route 145 and Diamond Pond Road. Beaver, loons, and a variety of songbirds are also common in and around the pond. Drive slowly on rural roads, as moose collisions are a real risk.
- Day trip to the Connecticut Lakes EasyRV parking available
The four Connecticut Lakes lie a short drive north of Coleman along US Route 3 toward Pittsburg and the Canadian border. Visitors can fish, paddle, and pull off at scenic overlooks including the headwaters of the Connecticut River. Pullouts and day-use areas generally accommodate tow vehicles and smaller RVs.
- Mountain biking and gravel riding ModerateRV parking available
Quiet backroads and forest roads around Stewartstown and Dixville offer long, low-traffic gravel rides straight from the campground. Riders should carry tools, water, and a map, as cell service is unreliable. The terrain ranges from rolling to steep.
- Hunting in season ModerateRV parking available
Coleman State Park and surrounding public lands are used for regulated hunting of deer, moose (by permit), grouse, and other species under New Hampshire Fish and Game rules. RV campers should check current season dates and wear blaze orange on trails during fall hunts. Target shooting is not permitted within the park.

How to get to Coleman State Park
Coleman State Park lies in Stewartstown, roughly 10 miles east of Colebrook, New Hampshire, off Diamond Pond Road. Expect about 3 to 3.5 hours from Concord, NH (around 170 miles) and roughly 4 to 4.5 hours from Boston; Montreal is about 3 hours to the northwest. RV drivers should plan for narrow, winding rural roads with frost heaves, long stretches without fuel or cell service, and the final gravel approach on Diamond Pond Road, which can be slow for large rigs. The closest commercial airports for fly-and-rent trips are Burlington (BTV) in Vermont and Manchester-Boston Regional (MHT) in southern New Hampshire.
