Soneva Kiri, Koh Kood

Soneva Kiri on Koh Kood pioneers eco-luxury with treehouse dining, an open-air cinema, and a private beach that spans 1.5 kilometers—30% longer than #3 (Mandarin Oriental, Bangkok)’s riverside promenade. Rates begin at $1,800 per night, and 85% of its energy is solar-powered, making it greener than the average Thai resort by a factor of four. The property includes a 500-bottle wine cellar and a no-news policy to enforce digital detox, leading to 92% of guests extending their stay by at least two nights. It outperforms the category in sustainability, with a carbon footprint 40% lower than comparable luxury resorts in Thailand.
