Koh Phai (Koh Phai) is the largest island in the Koh Phai archipelago, located in the Gulf of Thailand, approximately 13 kilometers from Pattaya’s coastline. The archipelago consists of several smaller islands such as Koh Man Wichai, Koh Luan, Koh Klueng Badan, and other surrounding islets. Koh Phai is under the supervision of the Royal Thai Navy, which helps preserve its natural environment in pristine condition. There are no hotels, resorts, restaurants, or permanent facilities on the island, so visitors must prepare their own food, drinking water, and essential supplies. These limitations contribute to Koh Phai’s peaceful, simple atmosphere, making it distinctly different from other beach destinations in Pattaya.

The island’s terrain is characterized by rolling hills covered with lush natural forest. It is surrounded by clean white sandy beaches and crystal-clear turquoise waters, where the sandy seabed and coral reefs can often be seen from the surface. Most beaches are quiet and uncrowded, ideal for private relaxation. Visitors can sit back, enjoy the sea breeze, or rest under the shade of trees while listening to the gentle sound of waves, creating a truly calming and nature-immersive experience.

The most popular activity on Koh Phai is snorkeling around the island, where shallow coral reefs remain well preserved and are home to a wide variety of marine life. Colorful schools of fish can easily be seen swimming close to the shore. Other activities include swimming, fishing, and leisurely beach relaxation without the need for a rushed schedule, making the island perfect for those who wish to spend an entire day immersed in nature and the sea.

Another highlight of Koh Phai is the lighthouse on the hilltop, which visitors can hike up to for panoramic views of the surrounding sea. From this viewpoint, nearby islands and the distant horizon of the Gulf of Thailand can be seen clearly. The scenery from above feels peaceful and majestic, making it an excellent spot for photography and quiet moments away from the beach
