A coconut grove slopes towards a broad crescent of sand at Amanwella, a low-slung retreat outside Tangalle on Sri Lanka’s southern coast. Its thirty suites follow the contours of the hillside, pairing clean concrete lines and timber screens with private plunge pools and uninterrupted sea views. A long infinity pool runs parallel to the beach, while the restaurant opens to the palms and ocean from an elevated terrace. Below, the beach club places lunch and drinks close to the water, with coastal walks, surfing and wildlife excursions extending beyond the resort’s sheltered bay.
