Portsmouth overview

One of the oldest cities in the United States, Portsmouth offers an appealing blend of 17th century architecture, great outdoor activities and a thriving programme of cultural events.

Founded in 1623, the city has many buildings from its early days, and visitors can tour every major landmark on well described tours. Head to the evocative Strawbery Banke Museum to wander around a superbly preserved 17th century neighbourhood to experience a walk back in time.

More recently, Portsmouth has been a major naval centre, and you can learn all about that part of its history at the fantastic Albacore Museum, where visitors can tour a US Navy submarine.

The city is also in a beautiful natural setting, with plenty of activities for the whole family to enjoy. Take to the water slides and lazy river at Water Country water park, take a scenic cruise to the Isle of Shoals, or visit the fascinating Children’s Museum.

For adults, Portsmouth also offers the chance to sample some of America’s finest micro-breweries like Red Hook and the Smuttynose Brewery. Join tours and see why the craft brewing sector is so vibrant in New Hampshire.

There is also a packed schedule of cultural events, which stretches across the year. Be there for the spectacular Halloween Parade, take in jazz and dance events at the summer-long Prescott Park Arts Festival or time a visit to coincide with the Market Square Food Festival, held in June.

Beyond the city itself, New Hampshire has beautiful hiking country, great beaches like Hampton and historical sights like the Nubble Cape Lighthouse. See animals at York Wild Kingdom or learn about technology at the Seacoast Science Museum. It’s all possible in Portsmouth.

Getting around Portsmouth

To get the most out of a stay in Portsmouth, a rental car is a great idea. Drive into the countryside or cruise the coast as far as Boston.

There’s no better way to discover the many historical buildings than by taking a stroll.

Getting from the Airport to the City

Buses head from the airport to cities like Manchester and Boston, but the best bet for getting into town is to take a taxi or limousine from the terminal doors. There are also specialist airport shuttle buses that need to be booked beforehand, so plan ahead.
