A historic property, Wentworth by the Sea provides a charming getaway in New Castle. Complete with a saltwater pool, hot tub and Piscataqua River views to the Atlantic Ocean. The Marriott Hotel is located on an island, but still has easy access to the amenities of Portsmouth NH via a short car or shuttle ride.

Wentworth by the Sea Marriott Hotel and Spa is a member of the Historic Hotels of America. First constructed in the 1870’s it has changed ownership several times. The hotel’s most noteworthy event occurred in 1905 when the Russian and Japanese delegates booked blocks of space while they discussed ending the Russo-Japanese War. Memorabilia of the event are scattered throughout the property.

The price point during the off season is reasonable, the location is charming, and the property is mid luxury. Read on below for my full review of Wentworth by the Sea.

Arrival and Check-In – 7/10

Arrival to Wentworth by the Sea was a quick, scenic ride from the Lakes Region of New Hampshire. If you are arriving by plane, Manchester Municipal Airport (MHT) or Boston Logan International Airport (BOS) are within 1 hour of New Castle.

Driving onto the property is confusing due to the one entrance and exit. Oftentimes, guests would drive the wrong way leaving pedestrians scrambling. The decorative signage is not easily seen. Parking is complimentary. However, valet parking is available.

Our arrival was early as our Labor Day plans were cancelled due to the rainy weather. The front desk staff found an available room and upgraded us to a room with water views and a mini balcony.

Unfortunately, most of our stay was poor weather. We decided to extend our stay. The staff accommodated our request and honored our discounted rate.

Check-out was processed in the reception area. The invoice was correct, and payment was handled via credit card.

Bedrooms and Amenities – 8/10

While the Wentworth by the Sea is starting to show its age, it still provides a charming, coastal experience. A 3 star hotel with enough amenities to provide a relaxing yet brief get away.

The 161 guest rooms and suites each celebrate the coastal setting with a soothing palate that complements the historic elegance of the resort.

The rooms are equipped with Free Wi-Fi, flatscreens and desks, minibars, coffeemakers and a minifridge. We appreciated the fully stocked toiletries, comfortable bedding, and spacious bedrooms.

Our room was located on the second floor on the back of the hotel. We had views of the Piscataqua River and the Portsmouth Naval Prison.

Before your visit to Wentworth by the Sea, I would suggest packing ear plugs and eye masks. Sounds from the hallway are easily heard and lights from the smoke alarm blink throughout the night.

If I had to pick the star feature of this property, it would be the outdoor, heated saltwater pool with incredible views, especially at sunset. Beautifully landscaped with plenty of lounge chairs and umbrellas, this is a book worm’s paradise.

Take advantage of the indoor pool, spa, and fitness center while visiting. The gym has everything you need for a full workout. Treadmills, free weights, a Peloton Bike, yoga mats and more are provided.

Dining and Drinking – 6/10

As it was off season, many Portsmouth restaurants and bars were closed encouraging us to stay in and dine at SALT Kitchen and Bar. Hailed as one of Portsmouth’s top-ranked restaurants, SALT is a beautiful dining experience. You’ll see what I mean the moment you step inside.

Breakfast each morning is served in the formal dining lounge or the outdoor porch. The waitstaff remembered us and the chef accommodating to my gluten allergy. A quick travel tip, request a carafe of coffee as the service is slow in the morning. For those uninterested in breakfast, there is a free coffee bar setup in the restaurant.

Dinner and appetizers are served by reservation or by first come first serve at the bar. Each night, service was slow. Although not in any hurry, this was unfortunate as we were hungry.

Our highly rated food and drinks from the menu are the following:

  • Chocolate Almond Mousse (gluten free)
  • Margherita Flatbread (gluten free)
  • SALT Salad (gluten free)
  • Asian Pear Margarita
  • Blackberry Smash

We do not recommend the Duck Fat Popcorn appetizer. Traveling gluten free? Check out my guides to eating gluten free on the East Coast and Sandals Resorts.

Location – 8/10

Situated upon a hill, Wentworth by the Sea demands attention. The views are incredible of the Piscataqua River, Safe Harbor Wentworth and the Wentworth Country Club. I highly recommend catching a sunrise from Sanders Poynt, a short walk from the hotel.

According to Tripadvisor, 177 attractions can be found within 5 miles of Wentworth by the Sea. The best things to do in Portsmouth are the Strawberry Banke Museum, Market Square (loads of shopping and dining), Prescott Park and the Isles of Shoals. Be sure to also stop at Odiorne Point State Park where you’ll find views of the ocean, explore the remains of the World War II Fort Dearborn and learn at the Seacoast Science Center.

Wentworth by the Sea Summary – 7.25/10

A clean, yet slightly dated hotel near Portsmouth NH with historic charm and views of the Piscataqua River. While this “seaside” hotel did not include a rocky beach, the sound of crashing waves or expansive views of the Atlantic Ocean, we would visit again.

We would classify this as a mid-luxury resort with fairly priced rooms during the off season. Expect very high rates and at capacity bookings during the summer and fall.
