Koh Phai Beach

Koh Phai Beach is a small island tucked behind Koh Larn (Coral Island) in the Gulf of Thailand, a short boat ride from the Pattaya coastline. The beach is known for its remarkably clear, jade-coloured water and clean shoreline, making it a notable escape from the busier beaches closer to the mainland. Its relative remoteness keeps crowds manageable outside of peak tour group hours, and the island's natural rock formations have also drawn visitors interested in geology and coastal landscapes. The atmosphere at Koh Phai shifts depending on timing. When tour groups are absent, the beach is quiet and relaxed, with calm, clear water ideal for swimming and simply taking in the surroundings. Visitors can reach the island independently via a shared boat for around 30 baht per person, or arrange a private full-day boat rental through operators such as Manta Marina for a more exclusive experience. Private charters do tend to congregate in the same area, so those seeking more space may want to explore beyond the main landing point. Arriving early in the day is strongly recommended to secure a quieter stretch of beach before tour groups arrive. As there is no website or confirmed on-site services listed, visitors should arrange transport and supplies, including food and water, before departing from the mainland. Koh Phai is accessible without naval restrictions, making it a straightforward day trip for those based in Pattaya.
