Dive Site Location & Key Facts
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.
