Most travelers have never heard of Tangalle—and they're missing out. In this Sri Lankan gem, you'll find some of the best beaches on the island, like Goyambokka Beach, where you could lie out for hours under the gently swaying palms. You'll also find some serious adventure, if that's your thing. Go kayaking around the mangrove-lined Tangalle Lagoon or hike up to Mulkirigala Rock Temple for the best panoramic views. You can't go wrong with the food, either—from beachside bites to the food stalls around Tangalle Market, it's all out of this world.
