Lucy Stone Park is the final access point on the Upper Quaboag Blue Trail in Warren, serving as the terminus for smooth paddling conditions on the river.

The site offers parking and boat access for canoeists and kayakers; below this point the river becomes whitewater and is not recommended for paddlers unless skilled.

This location is named after Lucy Stone, a pioneering abolitionist, suffragist, and the first woman from Massachusetts to earn a college degree in 1847.
