This camping area is a nice spot if you are looking for a quiet place along the Connecticut River. This is a Vermont State Park, however, it is open for primitive camping only and advertised as boat-in only. That being said, you can access the camping area via VT102 but there is no signage so having a Vermont Atlas is most helpful. Boating in, the sites are easy to spot as there is a sign on the riverbank that says, "Lyman Falls State Park." If you chose to drive, you will have to park at a small parking area indicated by a few large boulders and then carry your things in about 200-250 yards.
I was here in early July and while there was an outhouse, there was a very active hornets nest occupying the privy making it absolutely unusable. The area also could have used some mowing and weed whacking.
There are three sites with nice large pines offering ample shade. Each site has enough flat space to pitch a couple of tents (anywhere from 2 to 5 depending on which site). One site has a picnic table and they all have fire rings. There is also a great swimming area in a large deep eddy and the remnants of an old dam can be seen upstream.
There are a few short walking trails, one of which leads to a pavilion though it isn't riverside. We drove north about 20 minutes to the Beecher Falls river access area and paddled back down to our campsite which was a nice little float. The Beecher Falls River Access area was just completed and is in great shape, making getting the boat down to the river super easy.
You can see other campsites on the New Hampshire side of the river with cars driven right down to the river bank. I am unsure who manages the camping area on that side.
