Spent two nights at Lost River Valley Campground with a big group of tenters. Loaned them our tent, and brought our PUP. Probably it's last trip before trading in for a newer model. The sites at this campground are close together and the roads make it challenging to navigate. There is no wifi, so if that's important to your vacation, something to think about. The campground is heavily wooded and has a river running through it, very quiet and scenic. Campground security came through starting at 10:00 pm, very very strict about quiet hours and especially only one car per site. Visitors or second vehicles were asked to be moved off the property. It's understandable considering how tight and twisty the roads are, more than one car per site will impede traffic flow. Otherwise the staff was helpful and they are always active throughout the campground so it's in very nice shape. Can't beat the location, so much to do in that area of NH.
