Wentworth by the Sea Opal Collection

What Wentworth by the Sea Opal Collection does

Wentworth by the Sea is a historic luxury resort located at 588 Wentworth Road in New Castle, New Hampshire, operating continuously since 1874 on a seacoast island site near Portsmouth. The property offers overnight accommodations in rooms and suites featuring clawfoot tubs, private balconies, fireplaces, and water views, alongside an on-site restaurant (SALT Kitchen + Bar), a full-service spa with a halotherapy Salt Lounge, an 18-hole golf course, tennis courts, pools, and gardens. It also operates more than 14,000 square feet of event and meeting space capable of hosting groups of up to 500 for corporate conferences, weddings, and social celebrations.

The business operates under a multi-revenue-stream model spanning room and suite bookings, food and beverage, spa services, event and conference services, recreation activities (golf, tennis, pools), and gift cards and merchandise. Distribution runs through the Opal Collection's centralized reservation platform (reservations.opalcollection.com), local and toll-free phone lines, an RFP-based corporate/group sales function, and the Spatime booking platform for spa appointments. Pricing is quote-based and varies by season, room type, and availability, with package add-ons (dining credits, spa credits, golf rounds) and promotional offers such as the 'Stay Three and Save' multi-night discount.

The resort is marketed under the Opal Collection brand, a portfolio of 30+ independently owned and operated luxury properties across Florida, Maine, New Hampshire, New York, and Tennessee, with the 'Opal' and 'Opal Collection' trademarks held by Portsmouth Corporate Financial Services, Inc. — the entity under which Wentworth by the Sea is operated. Customer segments are spread across individual leisure travelers and couples, corporate and business clients, celebrations and social events, and families and groups. The property has earned recent recognition including #3 Best Resort in New Hampshire (U.S. News & World Report 2026), #12 Top Hotel in the Northeast (Condé Nast Traveler 2025 Readers' Choice Awards), and #13 Top Resort in New England (Condé Nast Traveler 2024 Readers' Choice Awards), and is historically notable as the site where the Treaty of Portsmouth was signed in 1905 to end the Russo-Japanese War.
