Europe's Secret Beaches

Thanks to feisty locals with little patience for outside intrusion, the Mediterranean island of Corsica remains relatively undeveloped—despite its bright blue, perfectly clear water, rugged mountains, and bracing pine and eucalyptus forests. The Ortolo Valley, once a wine region, is especially peaceful. Explore the walking trails and small beach coves from Domaine de Murtoli, a compound of 16 renovated shepherd villas. murtoli.com

Between Portocolom and Porto Cristo, this white-sand beach, accessible only by boat or a rocky footpath, has swimming pool–like water, ringed by pine forests. One of the cliffs nearby grants access to a 1/3-mile network of underground (some underwater) caves. Pack water and a lunch, as there is nothing for sale here. It’s all about 20 minutes south from Manacor, where La Reserva Rotana, a 17th-century stone house, has been transformed into a private golf course and antique-decorated resort. reservarotana.com

Hurry to experience this unspoiled, seven-mile slice of the Atlantic shore an hour south of Lisbon. Its protected white sand and brisk waves, whitewashed village and thatched-roof shacks have seen the likes of designer Christian Louboutin, actress Kristin Scott Thomas, and super-decorator Jacques Grange. It won’t stay this tranquil forever: an Amanresort will soon be joining the golf, wine, and hotel complex developed by the local agribusiness giant Herdade da Comporta. herdadedacomporta.pt

Among the far-north wild Hebrides Islands lies Harris, whose vast white-sand beach and crystal-clear azure waters see more deer, otter, and dolphins than the kite-surfers it seems tailor-made for. A rare sign of civilization: a seaside weaver selling original Harris tweeds a few miles away.

Rocky cliffs and gnarled oak trees ring one of the more secluded stone beaches on the Kullaberg nature reserve in southern Sweden, which requires a brisk hike for access. You won’t be totally alone, but the crowds are nothing like they were at the turn of the century, when Ransvik was famously the first co-ed beach in Europe. Fifteen minutes to the south, in the sweet village of Arild, you’ll find the Strand, a chic B&B. Rooms in the main building, dating from 1904, have the best sea views. strand-arild.se

Not all of Sardinia is blinged-out like the Costa Smeralda. Head south to the 15th-century village of Orosei, whose historic center is made up of old stone houses like the cheerful Anticos Palathos B&B, 11 miles south of the Bidderosa Beach nature reserve. It shares the same pale white sands and transparent azure waters as up north, but not those Porto Cervo crowds, thanks to a policy that restricts the number of cars daily and the alternative of a two-mile walk, off a poorly marked exit on the SS125 highway. anticospalathos.com

The endless daylight of summer in Jutland, the far north of Denmark, is best enjoyed from Skagen, a colorful fishing village on a remote peninsula. It’s better still if you’re a guest at Hotel Plesner, with a farm-to-table restaurant in a 1907 house. A few minutes north of Skagen, around the Grenen Headland at land’s end, are dunes so displaced by wind that they’ve overtaken the medieval St. Laurentii church. The beach there is at the confluence Skagerrak and Kattegat seas, whose waves break the shore in opposite directions. hotelplesner.dk

Wade through the translucent shallows to reach the tiny islet facing this nature reserve beach at the southeastern tip of Crete. It’s unusually quiet and commerce-free, with pinkish sand and bright blue water (it takes either a bus or a car to get there). Chania, a charming village with a 15th-century Venetian harbor, is the site of the lovingly restored Casa Leone hotel. casa-leone.com

The most famous attraction on this tiny Mediterranean island off the Dalmatian Coast is the Blue Cave, a limestone sea cave so named for the refracted sunlight that glows an eerie blue. An equally worthy but lesser-known reason to visit: expansive Porat Beach, on the western and lee side, thanks to large limestone cliffs protecting it from high winds. It’s a scenic place to break for lunch or a drink at the small seafood restaurant and beach bar. crobeaches.com

The French jealously guard any spare spot of beach they can get to. But not that many get to Côte Sauvage, which lies opposite the oyster- (and people-) heavy Île d’Oléron, on France’s untamed west coast. Surrounded by a shaggy pine and green oak forest, between Ronce-les-Bains and La Palmyre, this 18-mile stretch of white sand is accessible only after a serious hike over the dunes. visit-poitou-charentes.com
