Skadar Lake in Montenegro was featured in Guardian’s top five freshwater beach holidays. The article on Lake Skadar states:

“Montenegro's most beautiful lake is dotted with islands, many with ruined monasteries, and is home to pelicans, herons and silver seagulls. There's no beach at the comfortable Plavnica eco-resort, but hire a boat from local fishermen or take a cruise to Murici beach, on a little island, where you can swim, or rest beneath the 100-year-old trees. The island's open-air restaurant serves superb roast carp. Plavnica Eco Resort (plavnica.info, 00 382 81 443 700), doubles from €200. Fly to Dubrovnik (a 2½-hour drive).”
