About Great Island Inn

A different kind of Lodging experience

When traveling do you miss the creature comforts of home? Not a fan of Laura Ashley bedspreads and victorian antiques in BnBs? Do large hotels feel nondescript and cold? Does staying in an AirBnB with the owner's belongings feel like you're intruding in their space? 

At Great Island Inn we offer modern apartments for the independent traveler in mind. Housed in a newly-renovated, 1820s home on New Castle island, our six guest studios feature fully equipped kitchens and in-room laundry. Whether you need a home base while visiting the Portsmouth area, are in town for an extended work trip, or are doing home renovations, we invite you to experience New Castle and the Seacoast like a local!


You like your independence, but sometimes you need an insider. We provide personal concierge services for guests during their stay. Looking for the best sushi in town? Want to know where to rent kayaks to explore our islands?  Need information about day trips to Portland, Boston, or Newburyport? Our local concierge has you covered. We are just a call or text away.

New Castle & the Area

Off the coast of Portsmouth, New Castle is New Hampshire’s smallest, easternmost town comprised entirely of islands. A quiet coastal town of just 968 residents, New Castle offers historic sites, lighthouses, beaches and outdoor activities within the serenity of a small New England village. We're just a scenic, five-minute drive to lively downtown Portsmouth – with extensive shopping, nightlife, entertainment and over fifty renowned restaurants.

Directly across the banks of the Piscataqua river you will find yourself in Maine’s southernmost town of Kittery. An eight-minute drive from New Castle, this seaside town is full of eclectic boutiques, art galleries, and hip restaurants. Fresh-caught Maine lobster is a must during your visit!
