The Salmon Falls River is a scenic waterway that forms part of the border between New Hampshire and Maine, offering paddlers a unique interstate experience. This tidal river flows from its headwaters near Acton, Maine, southward to its confluence with the Piscataqua River near Portsmouth, New Hampshire. The river's character changes from a narrow, winding stream in its upper reaches to a broader tidal estuary as it approaches the coast.

Paddlers can enjoy several distinct sections of the Salmon Falls River, each with its own charm. The Upper Navigable Section from Rollinsford to South Berwick offers a mix of flatwater and gentle Class I rapids, suitable for novice to intermediate paddlers. The Tidal Reach, stretching from Hilton Park in Dover to South Berwick, provides a pleasant estuary paddle with changing tides influencing the flow. For those seeking a shorter trip, the Rollinsford Section, also known as the Bicentennial Park Paddle, offers an out-and-back route perfect for recreational kayakers.

The river's difficulty ranges from flatwater to gentle Class I rapids, making it accessible to paddlers of various skill levels. However, those venturing into the tidal sections should be aware of changing currents and plan their trips accordingly. The best times to paddle are typically late spring through early fall when water levels are moderate and temperatures are comfortable.

Along the river, paddlers can spot a variety of wildlife, including ospreys, herons, and occasionally bald eagles. The riverbanks are lined with a mix of hardwood and pine forests, creating a picturesque backdrop for your journey.

Several points of interest dot the river's course. The historic Hamilton House in South Berwick offers a glimpse into 18th-century architecture and can be viewed from the water. The Salmon Falls Mill Historic District in Rollinsford showcases the area's industrial heritage. Paddlers can also explore the confluence with the Cocheco River, adding variety to their trip.

Access points are plentiful, with popular put-ins at Hilton Park in Dover, Bicentennial Park in Rollinsford, and various locations in South Berwick. These towns also serve as convenient bases for exploring the river, offering amenities and historical attractions of their own.

The Salmon Falls River holds significant historical and cultural importance. It played a crucial role in the region's early settlement and industrial development, powering mills and serving as a transportation route. Today, it continues to be an important recreational resource and natural habitat.

Safety considerations include being aware of tidal influences in the lower sections, watching for submerged obstacles, and respecting private property along the shoreline. Paddlers should always wear life jackets and check weather conditions before setting out.

While multi-day trips are less common on the Salmon Falls River due to its relatively short length, ambitious paddlers can combine sections for longer adventures. A popular option is to start in the upper reaches near Rollinsford and make your way down to the tidal sections, possibly extending the trip into the Piscataqua River for a more extensive journey. Whether you're seeking a short, relaxing paddle or a longer exploration of the region's natural and historical features, the Salmon Falls River offers a delightful paddling experience in the heart of New England.
