Head to the last town in NH on RT.3 before you hit the Canadian border. Called "Moose Alley" the area of Pittsburg has a very rugged off the grid feel with the border close by. Deer Mountain campground has 30 sites all neatly spaced out. We camped at site 10 & 21. Amenities are small as there are just outhouses. No showers or flushed toilets but firewood is available for purchase. You can shower down the road at the Lake Francis campground if you need to. The campground has access to hiking trails and fishing. The area has the four Connecticut lakes that offer plenty of recreation. The hiking is incredible as you have the Cohos Trail which stretches down to Massachusetts. We also day hiked over the border into Canada as the campsite is not a far walk to the border crossing. An hour out from the site you will have no cell service so if you are a cell addict this won't be the place for you. There is a small general store called Treats & Treasures not far from the site to go and get wifi so you can make a call or check in with folks.
A lovely campground in Southern VT, again very close to our favorite little hippie town Brattleboro VT. Campground has clean facilities, tent and lean-to sites. We booked last last month and stayed in the middle of the campground. The outer ring sites on the map have the most seclusion. Not a ton of hiking right from the campground, but we found some fishing and hiking nooks in a short drive
Located just over the CT border near Granby, Granville is a tiny secluded campsite. The problem is you can't trust the scale of the camp map online. We thought we had booked the most secluded site only to find that the sites are about 15 feet from each other. Not very enjoyable. Although there are a few sites that would be good for large groups. It is still a nice visit for a day hike. Tons of trials right off the campground. And lots of fishing off the Farmington River and local pond.
We have been to Wilgus twice in the last month. Just a few miles from Brattleboro this campsite is perfect for those who love to fish, kayak or canoe. Set on the banks of CT River Wilgus has tent sites, lean to's and 4 newly built cabins. There is also a boat launch for drift boats as well. Quiet campsite with hiking trails right from the campground. Bathrooms and showers were clean which is a theme in VT, they take great care of their parks. The cabin is great as it has a set of bunk beds and futon. Great for starting out with your kids.
Fort Dummer is nice little site very close to downtown Brattleboro. If you have ever visited the cool little boho downtown definitely check it out. Fill up on your favorite IPA and fresh food at the Co-op and you are 5 min from the campground. The sites are spaced out very well, we were at #22 which is set back from the road loop. You want to look at that area as the campground is near the highway. In this area you can't hear the traffic. Sites are spacious with fire rings and picnic tables. Bathrooms and showers a short walk. Two different hiking trails are in the park with plenty a drive away.
My wife and I along with our dog Wyatt make an annual trip to CC. There is a great secluded site off the road into the park. Site #2 on the left is a nice open space with a private outhouse and great views of Killington. Only a short drive from Brattleboro area there is a ton of hiking and also some decent fishing. The campground has both tent and lean to sites. Our site was a lean to, well constructed and in great shape. Bathrooms and showers are clean and take quarters. There are also 3-4 sites on top of the campground that offer better vistas…but I find that the sites are right on top of one another, great for a group. But can be annoying if your used to secluded sites. All in all its a great hidden spot. Make sure you visit Calvin Coolidge's historic home not far from the park.
I was searching for something remote that also had a good deal of hiking in the area. Deer Mtn is a no frills campground. But if you want a perfect campsite book #28. You need to carry in/out in the 1/2 mile walk to the site. But you have a secluded open site sitting on the 2nd CT Lake. Listen to the Loons call as you hopefully see a Moose in what is known as Moose Alley. Numerous miles of trails and your only 2 miles from hiking the international boundary line by the US Customs Border house
