Pattaya city authorities have initiated Thailand’s first formal licensing pilot for Sea Walker operations off Koh Larn, marking a significant step in regulating one of the region’s popular marine tourism activities.

The move comes as Pattaya seeks to balance economic benefits from underwater tourism with improved safety standards and environmental protection.

Under the new framework, which is set to begin issuing permits in October 2025, operators will need to comply with detailed licensing requirements encompassing safety training, certified equipment, and annual inspections.

The framework was presented in a meeting between city officials and local Sea Walker operators, with Deputy Mayor Wuthisak Rermkijakarn outlining a set of nineteen conditions operators must meet before receiving approval to operate.

The regulatory effort also designates specific operating zones away from coral reefs to minimise ecological impact, aligning with broader efforts to protect marine habitats around Koh Larn and Koh Sak.

Pattaya officials plan to form a monitoring committee responsible for inspecting services and ensuring compliance with the new standards.

The licensing scheme places Pattaya at the forefront of structured underwater tourism oversight in Thailand, promising tourists a safer and more sustainable experience while supporting the city’s ambition to enhance its international reputation as a responsible travel destination.

Operators are expected to adapt to the licensing regime under continued supervision from Pattaya City and relevant marine authorities.
