Nestled In Essex Is England's Serene Island With Beaches, Coastal Vibes, And Fresh Seafood

England's coastline charms with cozy cottages, delicious seafood, maritime history, and wind-swept beaches. Though perhaps underrated for international travelers focused on Big Ben or Buckingham Palace, coastal enclaves capture serene slices of British life outside the urban hub. Along the Sunshine Coast, a nickname given to Essex's 350-mile shoreline in Southeast England, lies the scenic island of Mersea. This small island is shaped roughly like an oyster and is known for said savory bivalves — as well as a plethora of other local seafood, sand-and-shingle beaches, and pastel beach huts. 

Mersea is connected to the mainland via a half-mile causeway first built sometime around AD 700. The road and footpath, known as the Strood, floods twice a day during high tides, making the island temporarily inaccessible and all the more romantic for its seclusion. As one travel blogger put it, Mersea has "one of the most Instagrammable beaches in the U.K.," and Condé Nast Traveler described it as Victorian Gothic and "the English Coast at its earthiest and most beguiling." 

Mersea is just over 2,500 acres, about 5 miles long and 2 miles across, with a year-round population of about 7,000. West Mersea is the island's larger, more developed village, featuring destination-worthy dining, lodging, and shopping, whereas East Mersea is less developed and farther from the causeway, with more parks and trails that make it feel more remote. Here, visitors can explore Cudmore Grove Country Park with its blend of sandy beach and grassy fields traced with flat walking paths. It's an ideal bird-watching site, attracting migrants and local marsh birds. At less than a two-hour drive or train ride from London, Mersea makes for an ideal day or weekend trip. From nearby scenic Colchester, England's oldest city, it's just a 45-minute scenic bus ride to the island.

Native oysters grow in the brackish Blackwater Estuary that surrounds the island, and seafood has been one of the island's primary industries since Roman times. One of Mersea's seafood staples is The Company Shed. Formerly a shack built for oystermen, today it's a no-frills seafood restaurant with a reputation as one of the best seafood shacks in the U.K. 

The Company Shed encourages patrons to BYOBB (bring your own bread and butter) to accompany the array of grilled, smoked, and fresh seafood on the menu. "This is not a traditional restaurant, so just lower your expectations a little bit before visiting; it's a bit rough and ready and a bit cold, but that is the point," noted one Google Maps reviewer. "The food is incredibly fresh and up there with the best of each I've ever eaten, anywhere in the world," wrote another. For a small corkage fee, you can also bring your own wine, but the restaurant also sells prosecco and locally produced wine from Mersea Island Vineyard, a winery and bed-and-breakfast located in East Mersea.

Seafood at Dawn is a family-run spot in West Mersea overlooking the estuary and serving local fresh catch and tapas-style combos. Or taste quintessential fish and chips at fast-casual Mersea Island Fish Bar, which also serves classic savory pies and stone-fired pizzas. For coastal classic vibes and a menu spanning land and sea, The Coast Inn is a dependable pub serving cask ales, cakes, and fresh catch, scratch-cooked meals, and occasional live music by evening. "Bonkersly good," wrote a Tripadvisor reviewer. "Food, service, and price, as well as outstanding views across the water."

Immersive travelers might want to try their hand at a classic Mersea activity: crabbing. The estuary is rich in various species, and specially marked spots along the causeway and the West Mersea jetty designate where public catch-and-release crabbing is permitted. Local shops sell lines, hooks, buckets, and bait, but you can also DIY a rig with a rasher of bacon and a net.

Part of Mersea's picturesque popularity is its pastel beach huts, located on West Mersea Beach, a sandy-shingly stretch of shoreline. Available from The Little Beach Hut Company as day rentals, each provides guests with a relaxing, private area during their day on the beach. There's also the adjacent West Mersea Holiday Park, with 50 sites for overnight campers, as well as a restaurant, playground, laundry, and community areas. Meanwhile, in East Mersea, Mersea Barns offers a sumptuous cafe and luxury glamping experiences along with seasonal events.

If you plan to spend the night, The White Hart is a modernized historic pub and six-room boutique hotel that serves a noteworthy Sunday roast, or check out Monkey Beach Cottage, one of the oldest buildings on Mersea and an old fishermen's cottage now redesigned as a captivating vacation rental. The Victory at Mersea is another waterfront hotel and pub in the heart of West Mersea that offers convenient walkability.  While you're in the area, explore the rest of Britain's southern coast, including the lively Clacton Pier at Clacton-on-Sea, another charming coastal town, or historic Harwich, a coastal city with beaches, military forts, and antique shops.
