Green Hotels & Resorts in Koh Samui Islands from AU$257

"Truly a world-class resort! My wife and I stayed here for a week last year and had an incredible time. Some of the friendliest staff we've encountered and our room was amazing. The gym is fully equipped with everything needed for a good workout. We will definitely miss the ocean views and infinity pool. Definitely plan on staying here again when we come back to Ko Samui. Highly recommended!"

"Could not fault the staff they were amazing, friendly, helpful, polite couldn’t ask for more! Our villa was beautiful and we had a fabulous stay!"

"The room was breathtaking and the atmosphere of the whole resort was perfect for a vacation get away at Koh Samui, I’m really happy with the service that the Avani+ team provided and the check-in and check-out process was smooth and fast. The amenities with the rooms were excellent, and the Avani Spa is a must try. "
