Safari tours of Sri Lanka’s pleasantly relaxed national parks encounter leopards, water buffaloes, all manner of birds and a passe of primates.The Verdant tea plantations and rainforested peaks beckon walkers, trekkers and those who just want to see them from a spectacular train ride. Then there are the beaches. Dazzlingly white and often untrodden, they ring the island so that no matter where you go, you’ll be near a sandy gem.
