Explore the Granite State from Our Seaside Resort

The stunning New Hampshire seacoast at your fingertips

Wentworth by the Sea is the crown jewel of the island of New Castle, a historic settlement located just 15 minutes from downtown Portsmouth. The expansive, elegant resort features two pools, an on-property spa and fitness center, clay tennis courts, and gardens built for exploring. The hotel is perfectly positioned to offer guests access to New Hampshire’s finest outdoor activities, including hiking, boating, biking, golfing, and many more pasttimes.

There are few better places to enjoy the outdoors than the coast of New Hampshire. In the summer, its waters come alive with boaters. When fall arrives, the foliage is among the most breathtaking in the country. Outdoor pursuits continue in winter, when ice skating season begins.
