Sri Lanka’s first design hotel has been built according to nature’s golden ratio, with freestanding suites spiralling around the hillside like the coil of a shell, from the lake shore to the vantage point at the top where a watertower houses the last three rooms.

Tri’s stellar holistic programme combines teacher Lara Baumann’s own quantum yoga, based on Ayurvedic principles, with treatments from visiting therapists. Doubles from about £205 half board
