About this spot

Bay 1, known locally as Ao Ter, sits off Thailand's coast as an unprotected dive destination open to year-round exploration. The site hosts documented marine life across 12 species observations, offering divers a chance to encounter Thailand's diverse underwater inhabitants. Community video evidence from three separate visits documents the site's conditions and marine activity, providing real-world reference for what to expect. The site operates outside a marine protected area, making access straightforward for visiting divers. Current coral bleaching monitoring shows alert-level conditions, reflecting broader environmental pressures on Thai reef systems. This context matters: divers visiting should understand they're exploring an active ecosystem under stress, not a pristine reserve. Bay 1 works as a year-round destination, meaning seasonal variation is minimal enough that planning doesn't hinge on narrow windows. Water conditions, depth, and difficulty remain variable—check with local operators for current site specifics before booking. The combination of accessible location, documented marine life, and community video references makes this a solid choice for divers seeking authentic Thai diving without designation as a formal protected site.
