About Merrimack River
Merrimack River offers a refreshing cold spring experience in New Hampshire, inviting you to swim in a gentle eddy along its flowing waters. The site combines a sandy beach vibe with scenic views of an old power station and nearby remnants of a railroad trestle, adding historical intrigue to your dip. This spot embodies the rugged charm of primitive hot springs in New Hampshire, blending natural beauty and a touch of local history.
Getting There
You can reach the Merrimack River swimming hole easily by car with no hiking required, making it one of the more accessible cold springs in New Hampshire. Parking is limited, so arriving early in the day helps avoid the busiest times. The location’s proximity to nearby trails means you can combine swimming with fishing or mountain biking along the riverbanks.
What to Expect
Expect cool, clear river water with small rapids visible just south of the swimming hole, formed by the old railroad trestle's ruins. The sandy beach provides a comfortable spot to relax, but the area is popular and often busy during summer weekends. Facilities are minimal, so the atmosphere stays authentic and natural, typical of New Hampshire swimming holes.
Tips for Visitors
Visit during weekday mornings or early summer to beat the crowds and enjoy a peaceful soak. Bring water shoes for easier footing around rocky edges and pack snacks, as there are no on-site services. Remember, there is no entry fee, but be prepared for limited parking and respect the natural environment to keep this primitive spot inviting for all visitors.
