Ko Kut, Trat

Ko Kut stands out as Thailand’s fourth-largest island yet remains remarkably untouched by mass tourism. The island’s pristine white sand beaches stretch for kilometers along crystal-clear turquoise waters, offering some of the country’s finest swimming conditions with gentle waves and excellent visibility for snorkeling. Unlike the developed resort islands of southern Thailand, Ko Kut maintains its natural charm with dense jungle covering most of the interior and only a handful of small fishing villages dotting the coastline.

The island’s main beaches each offer distinct experiences, from the expansive Khlong Chao Beach with its perfect swimming conditions and nearby waterfall, to the more secluded Ao Tapao where you can walk for hours without encountering crowds. Coral reefs lie just offshore, making snorkeling rewarding with minimal effort – you’ll spot colorful fish, sea turtles, and vibrant coral formations in the clear waters. Fresh seafood restaurants operate from beachfront locations, serving grilled fish, crab curry, and traditional Thai dishes with your toes in the sand. Natural shade comes from coconut palms and casuarina trees lining most beaches, while the sound of waves and tropical birds creates a peaceful soundtrack.

Ko Kut radiates tranquility that feels worlds away from Thailand’s busier destinations. The absence of large resorts and limited development means beaches remain spacious even during peak season, with plenty of room to find your own quiet spot. Local fishing boats bob in calm bays while longtail boats offer unhurried island-hopping trips to nearby islets. The pace of life moves slowly here, encouraging visitors to disconnect and simply enjoy the natural beauty surrounding them.

Visit during the dry season from November to March for the best weather and calmest seas, though April and May can also be pleasant with fewer crowds. Ferries operate from Laem Sok pier in Trat province, taking about 90 minutes to reach the island. Bring reef-safe sunscreen, snorkeling gear if you have it, and cash since ATMs are limited. Ko Kut offers an authentic taste of tropical island life that’s becoming increasingly rare in Southeast Asia.
