Paddling near Portsmouth, NH

Sitting directly on the Piscataqua River in Rockingham County, Portsmouth anchors a dense network of tidal creeks, salt marshes, and bays along New Hampshire's short 18-mile coast. The marquee water is Great Bay, a 6,000+ acre estuary with over 150 miles of shoreline — the second largest inland estuary on the East Coast — fed by a river system that ranges from beginner-friendly flatwater to some of the continent's fastest tidal currents.
