Groton Conservation Trust -- Lawrence Woods & Scenic Trails

This is an area that I've walked in frequently, first to Geo cache then to help a lady friend with dogs. It's been a safe place to hike along a beautiful waterway flowing along at at a quick but peaceful pace. The woods are old and it's hard to find a very solid stick for a dog to chase but it's such a lovely walk with views of the river and paddlers stroking up and down river.
Along the banks are tree swings to leap into the river.
There's a big cluster of old rhododendron that is surreal when in blossom. This is a truly marvelous place to stroll through.

On the river kayaking. Beautiful and peaceful. Muskrats, beavers, cranes.

Adjacent to, and probably part of, the Groton Conservation lands is the Groton Place dog park. It's 100+ acres of field, woods, amd the Nashua river where dogs can run off leash. We were there the day after Thanksgiving with three dogs, and we saw a couple dozen more. They had a great time, there are bags and bins available everywhere, and the trails are easy for older people and dogs.
