Ko Phrao Nok (Ko Sai Khao), Trat

Ko Phrao Nok, more commonly known as Ko Sai Khao or White Sand Island, stands out among Ko Chang’s satellite islands for its pristine white sandy beaches that give the island its nickname. This small uninhabited island offers some of the clearest waters in the Ko Chang archipelago, making it a favorite destination for snorkeling enthusiasts and beach lovers seeking untouched natural beauty just a short boat ride from the main island.

Snorkeling around Ko Sai Khao reveals vibrant coral formations and diverse marine life, with excellent visibility extending several meters into the crystal-clear water. The island’s main beach stretches along its western shore, where soft white sand meets turquoise waters perfect for swimming. You’ll hear only the gentle lapping of waves and occasional calls of seabirds, while the salty sea breeze carries the fresh scent of ocean spray. The shallow waters near the beach make it ideal for families, while the deeper areas around the island’s edges offer more challenging snorkeling opportunities among colorful reef fish and coral gardens.

Complete tranquility defines the Ko Sai Khao experience, as this uninhabited island remains free from development and crowds. The peaceful atmosphere encourages visitors to slow down and appreciate simple pleasures – lounging on pristine sand, exploring underwater worlds, or simply watching the interplay of light on water. With no commercial activity or permanent structures, the island maintains its natural charm and offers a genuine sense of escape from modern life.

Visit Ko Sai Khao during the dry season from November to April for the best weather and sea conditions. Longtail boats and speedboats operate day trips from various piers around Ko Chang, with journey times ranging from 15 to 45 minutes depending on your departure point. Since no accommodation exists on the island, plan for a day trip and bring water, snacks, and sun protection. The combination of easy accessibility and unspoiled natural beauty makes this white sand retreat well worth the boat journey.
