Small but with a deep attachment to the nation’s history, this island town has many scenic walkways and relics from past battles.

Explore old forts on New Castle that have proudly withstood the waves for centuries. Colonial soldiers once fought here for control of the United States. View intricate blue-green waterways that wrap around scattered land masses and dip your feet in the shallows at pristine beaches.

The only town in the state made up completely of islands, New Castle is much more than just a geographical rarity. Arrive at the northern port of the main island and head straight to Fort Constitution, previously known as Fort William and Mary. The fort reaches out on a peninsula into the Piscataqua River. Colonists stole nearly 100 barrels of gunpowder from here in one of the first acts of the Revolutionary War. Additional ramparts and an outer wall twice the size of the original were built in 1808. Wander out to the lighthouse that sits on the very edge of the rocky point and breathe in the fresh, salty air that whips along the cliffs.

From here amble down the eastern coastline, pausing to bask in the sun at empty white-sand beaches and swim where the river meets the clear Atlantic Ocean. Stroll through grassy Great Island Common, taking in forested routes and icy ponds in winter.

Reach rugged Jerry’s Point where further defenses greet you, this time in the shape of the spooky ruins of Fort Stark Historical Site. This was named after John Stark who was the commander of forces at the Battle of Bennington in 1777. Stroll along the rocky shoreline just below and enjoy the view over stunning Little Harbor to the west.

New Castle is an hour’s drive east of Concord. Arrive at Portsmouth and cross the bridge for the short final leg to the island. Stay at luxurious Wentworth by the Sea near the marina or find accommodations in and around Portsmouth. The island itself has a few cafés and stores.
