The New Meadows River is a tidal river flowing through Brunswick, Maine, offering a protected coastal paddling environment. The primary public access for paddlers is the Sawyer Park Boat Landing in Brunswick, which features a paved, all-tide launch ramp, a large parking lot, and restroom facilities. Another noted put-in is Thomas Point Beach, where a commercial outfitter operates. The river is characterized by a mix of narrow channels and wider bays, including Middle Ground and Thomas Bay, and it eventually opens into Casco Bay. Paddlers must plan their trips carefully around the significant tidal currents. The river is a popular route for sea kayaking, and trip reports emphasize the importance of coordinating paddling direction with the tide stages to avoid excessive effort, such as planning an outgoing tide for a southbound departure and returning with an incoming tide. Wind is another key factor; a prevailing sea breeze from the south can provide a helpful tailwind on the return northbound leg, but paddlers should always check marine forecasts.

The waterway sees a mix of boat traffic, including lobster boats and pleasure crafts, requiring paddlers to be mindful, especially in the constricted channels. Wildlife sightings are common, with bald eagles, osprey, cormorants, great blue herons, and various waterfowl along the shores. Horseshoe crabs can be observed in the shallows, particularly around the full moon in June. Notable points of interest include Howard Point, Woodward Point, and several islands such as Merritt Island, which is part of the Maine Island Trail and offers a potential lunch stop. Malaga Island, near the river's mouth, is a historic preserve with a seasonal float for landing. The overall experience is suitable for paddlers of various skill levels, offering a relaxing paddle with scenic views of homes, docks, and natural shoreline. The best season for paddling is summer, and while the river is generally protected, afternoon southwest winds can create waves where the fetch is longer. Standard safety practices like wearing PFDs are emphasized.
