This stretch of conservation land abuts the Nashua River Rail Trail. You're free to explore the land if you want to hop off your bike, but it's kept in such a natural state that you won't even find maintained trails on it.

There is a nice, new, and large parking lot at the Ayer end. It crosses a few busy roads, so be aware of this if you bring young kids.
