General Overview

The Treasure is an all-villa resort comprised of 37 units and located on the untouched island of Koh Madsum. Opened in mid-2013, the property boasts a wide range of facilities and services for guests to enjoy from this intimate island destination.

The Treasure’s design incorporates high-quality materials including teak wood, bamboo, limestone and marble, with many open-air venues from which to enjoy the numerous views from either side of the island. All villas offer outdoor Salas, while others come with beachfront views and private swimming pools.

The resort spans from one side of Koh Madsum to the other, where guests can enjoy a coral reef and white sand beach. Noticeably absent are many of the features that have become notoriously well known to islands in the Gulf of Siam: there are no bank machines, fast food chains, shopping centers, cars, or even private residences on Koh Madsum. What you will find is The Treasure Resort, a haven of serenity surrounded by two stunning shores, one with a white sand beach and the other with a coral reef.

Here, we encourage you to get lost so that you can find yourself again. Take a step back in time and relive the beauty and calm of island life as it was meant to be. A true Treasure awaits your discovery.


The Treasure is located on Koh Madsum, a small island 30 minutes by boat south of Koh Samui in the Gulf of Thailand. Koh Samui is situated off the eastern coast of Southern Thailand and is the largest of an archipelago of more than 80 islands. Bangkok Airlines operates flights from Bangkok’s international airport directly to Samui Island regularly throughout the day and the flight takes just under an hour. The Treasure can arrange round-trip transfers for guests from the airport to the resort’s two private piers, and then to the island itself via long-tail boat or private speedboat.


All 37 Villas at The Treasure are free-standing individual units, each with outdoor balconies or lounge areas and high-quality amenities. Villas are outfitted with king beds ideal for couples, and come with a sofa bed upon request for additional guests.
