Portsmouth to Atlantic City: Ultimate Road Trip Guide

The drive from Portsmouth, NH to Atlantic City, NJ spans roughly 350 miles along I-95 and I-295, crossing through six states.

New Hampshire's coastline is brief but scenic, with the Isles of Shoals visible off Portsmouth. The drive through Massachusetts passes the urban sprawl of Boston, then the rolling hills of Rhode Island and Connecticut. The most dramatic natural shift occurs near New Haven, where the landscape flattens as you approach the New Jersey Pine Barrens—a vast, protected forest that contrasts sharply with the industrial corridor.

Local commerce along the route includes classic New England seafood shacks like Bob's Clam Hut in Kittery, ME (just over the bridge from Portsmouth) and Anthony's Pier 4 in Boston. In New Jersey, farm stands selling Jersey tomatoes and blueberries are common in summer.

Notable stops include the Hooksett Welcome Center in NH (mile 11 on I-93) and the Molly Stark Service Plaza in MA (on I-95).
