Koh Sak – Pattaya

Koh Sak is one of Pattaya's most popular and picturesque coral dive sites, located among the near islands just a short boat ride from the mainland. The horseshoe-shaped island is surrounded by healthy coral reefs, sandy slopes, and rocky outcrops, creating a diverse underwater environment that is ideal for exploration and marine life encounters.

With a maximum depth of 18 meters and generally calm conditions, Koh Sak is an excellent dive site for beginner and Open Water certified divers. The gentle sloping reefs, easy navigation, and sheltered bays provide a relaxed diving experience while still offering plenty to discover beneath the surface.

Divers can expect to encounter schools of fusiliers, butterflyfish, angelfish, rabbitfish, blue-spotted stingrays, nudibranchs, and occasionally sea turtles cruising along the reef. The combination of vibrant corals, abundant fish life, and good visibility makes Koh Sak one of Pattaya's favorite sites for underwater photography and leisurely reef dives.
