What to do
Swimming at natural beaches: Jamaica State Park Campground offers a sandy riverfront area where campers can cool off during hot summer months. One visitor shared, "The campsites were beautiful with the river behind us... they also had a playground to play at, and a boat dock to kayak."

A Jamaica State Park visitor noted, "There is plenty of trails in the area and you can go to the waterfall/rock slides and take a dip in the pools."

A camper described, "There's fabulous hiking trails with lots to see, including a pond, waterfalls, and streams."

What campers like
Clean facilities: Campers consistently praise well-maintained campgrounds in the region. At Jamaica State Park Campground, one reviewer mentioned, "The bathroom facilities, while rustic, were clean," while another noted, "Bathrooms and showers were also kept nice and clean which is always a plus."
Wildlife viewing opportunities: Many sites offer chances to observe local fauna. A Newfound RV Park visitor wrote, "A fun plus to the campground was the nature walk and stream on the property. This was a great place to take our dog for a quick walk. There's even a little 'wishing' bridge that crosses the stream."

What you should know
Seasonal availability variations: Most rv parks near Grantham, New Hampshire operate on limited schedules. Woodmore Family Campground runs "from Mother's Day to mid-October," while Tree Farm Campground operates "from May 10th to Oct 19th." Jamaica State Park remains open "from May 12 to Columbus Day weekend."
Cell service reality check: Internet connectivity varies throughout the Upper Valley region. A Riverbrook RV guest remarked, "The wifi worked great...especially when compared to other campgrounds we've been to," while others have noted spotty service at more remote locations.
Wildlife encounters: Campers should prepare for normal woodland creatures. One Sandy Beach camper described "an over-abundance of gypsy moth worms. Crawling over everything and the concern of bringing them home with us to infest our trees. Not the campground's fault, but of concern nevertheless."
Tips for camping with families
Look for kid-friendly activities: Several campgrounds offer specific amenities for children. A Sandy Beach Campground visitor noted, "We enjoyed our stay. The first site we got was way too small for our tent and they accommodated us... Playground is on the beach. They don't allow sparklers so that was a bummer on the 4th, but still got to see fireworks."
Scout playgrounds and game areas: Indoor options during inclement weather matter. One Meredith Woods Four Season Camping guest mentioned, "They also have a nice game room for kids or grown ups that struggle to leave technology behind. They also have a nice little playground which is always the first thing my little buddy asks to go find."
Check playground age-appropriateness: Not all play equipment works for all ages. A Meredith Woods visitor cautioned, "Family with kids the only down, wish the playground was bigger, and height smaller. Not a structure for small children."
Tips from RVers
Site access considerations: Approach roads can present challenges for larger rigs. A Woodmore camper advised, "Sites in back are ok with trees and different levels. Sites are a little closer than I usually find."
Winter RV preparation: For cold-weather camping, verify facilities. A Meredith Woods winter camper shared, "Snow ploughing happens regularly and reliably. Indoor pool and hot tub are amazing on a snowy frigid winter day. Utility sink for dishes available in heated bathhouse."
Site type selection: Different parking configurations offer various advantages. A Sandy Beach RV visitor explained, "Small but well organized campground. TT members will find all the comforts of home... Mostly a 5th wheelers park but you can see a 34 foot class A here and there so don't fret, there is room."
