🏆 NH’s Ocean Beach — One of New Hampshire’s precious few ocean beaches — the state has only 18 miles of coastline!
Jenness State Beach is one of the jewels of New Hampshire’s remarkably short coastline — just 18 miles, the shortest of any US coastal state (compared to Maine’s 3,478 miles!). Despite its tiny coast, New Hampshire packs incredible beach experiences into this compact stretch. Jenness offers 300 feet of sandy oceanfront with views of the Isles of Shoals — a cluster of islands 6 miles offshore that were a thriving fishing community in the 1600s and inspired poet Celia Thaxter’s famous garden and literary salon.

Frequently Asked Questions
Why is NH’s coastline so short?
Geography — Massachusetts and Maine squeeze New Hampshire into just 18 miles of Atlantic coastline. When colonial boundaries were drawn, New Hampshire got the short end. Despite this, the 18 miles include excellent beaches (Hampton, Jenness, Wallis Sands), historic Portsmouth (one of America’s oldest cities), and the Isles of Shoals. New Hampshire maximizes every mile of its coast.
Make it a road trip: Pair a visit with Wentworth-Coolidge Mansion State Historic Site (a short drive away) or Wallis Sands State Beach (a short drive away).
