Embark on a 3-day road trip along New Hampshire’s U.S. Route 1, hugging the short but stunning Seacoast from the southern border near Seabrook to the northern Piscataqua River crossing into Maine. This itinerary covers about 18 miles of coastal highway with inland detours, featuring 1-2 hours of driving each day, immersing you in the Granite State’s paradoxes: rocky shores, historic ports, and a live-free-or-die ethos blending Yankee grit with fresh seafood.

Drawing from New Hampshire’s revolutionary spirit and lobster trap traditions, this journey mixes iconic beaches with off-the-beaten-path spots like forgotten lighthouses and tidal pools, fusing adventure, history, and seasonal delights like apple cider donuts. Ideal for summer swims or fall foliage, pack layers for sea breezes, sturdy sandals for tidepooling, and a sense of humor for “what exit?” jokes.

Navigation via latitude and longitude coordinates will guide you, with options to extend inland to Portsmouth for craft beer scenes.
