Koh Phai, also known as Bamboo Island, is the largest island in a small group collectively called the Bamboo Islands, located around 13 kilometers offshore from Pattaya in Chonburi province. The group includes Koh Phai, Koh Manwichai, Koh Luam, Koh Klung Badan, and other small islets. These islands are under the protection of the Royal Thai Navy, which helps preserve their pristine condition and natural beauty.

The highlight of Koh Phai is its tranquil, undeveloped beaches, ideal for travelers looking to escape the crowds of Pattaya. On top of the island's hill stands a small lighthouse, offering panoramic views of the surrounding Gulf of Thailand. Visitors can enjoy a variety of activities including swimming in crystal-clear waters, fishing, or diving to admire the rich coral reefs.

As the islands are uninhabited, there are no hotels or restaurants, making it perfect for peaceful day trips. The marine life is abundant, making it a favorite among divers and snorkelers. It’s advised to bring food, water, and snorkeling gear when visiting.

Boats can be hired from the South Pattaya pier, with options of speedboats and large boats:

• Speedboats (10–15 passengers): Travel time approximately 35–45 minutes, suitable for small groups. Rental fee ranges from 1,000 to 1,500 Baht.

• Large boats (20–80 passengers): Travel time approximately 1.5–2 hours, suitable for larger groups or parties. Rental fee ranges from 1,500 to 2,500 Baht.

Boat rental fees vary depending on boat type, group size, and destination. Some packages may include snorkeling gear, life jackets, and lunch.
