Dive Site Overview
Mai Thon has a distinct role in the local dive scene, reportedly owned by one of Thailand's princesses. Historically, it serves as a primary alternative when more distant dive sites become inaccessible due to challenging weather conditions like strong winds and high waves.
Close to Chalong Bay, Phuket's main departure point for scuba boats, it's a practical choice for day trips. A comprehensive depth range, typically between 2 m and 25 m / 7 ft and 82 ft, accommodates a wide spectrum of divers. On the island's eastern side, gently sloping shallow areas reach a maximum of 14 m / 46 ft, suitable for beginner divers, Discover Scuba Diving experiences, and initial Open Water Diver courses.
More experienced divers can explore deeper sections, such as the South Tip, though currents there can be more pronounced. Despite sometimes being a backup, Mai Thon consistently delivers a rewarding diving experience, showcasing vibrant coral formations and diverse marine inhabitants.
Best Time to Dive
Optimal diving conditions at Mai Thon generally align with periods of lower rainfall and calmer seas. December to April consistently show "Excellent" or "Good" dive scores.

Wave heights are also typically lower, averaging between 0.4 m and 0.6 m / 1.3 ft and 2 ft, contributing to more stable boat conditions and better visibility.

However, Mai Thon often becomes a favorable backup site during these months, especially with dives concentrating on the more sheltered eastern side of the island.
