Souhegan River Access in Hillsborough County provides multiple public access points for paddling and fishing along the river corridor.

Key access sites include Weston Park in Merrimack (shorebank access), Amherst Canoeport at Boston Post Road (with wooden steps and parking), and several informal bridge crossings in towns like Wilton, Milford, and Merrimack that offer walk-in fishing access.

The river offers varied paddling conditions from Class II-III whitewater in the upper reaches (Greenville to Wilton) to flatwater sections suitable for family canoe outings downstream of Milford.
