Drive along Mill Road from Rye, you will see on the left a sign reading Carroll M. Fogg Conservation area. I miss the sign whenever I drive from Hampton. It is a small entrance with enough parking for about 3 cars. Park there and you will see a trail that I could not find on the internet or any other listing.
Stop there and there is a trail that is a beautiful walk. It is not a long walk, but long enough to take a good walk with kids and a dog. The trail is flat enough to take a bike ride, but it may not be long enough. It is a perfect walk to relax your mind after a hard day at work or home. The trail is scenic to be able to clear your mind. Here are some pictures.
