Pattaya is one of Thailand's easiest places to stack boat dives into a short schedule: reefs close to town, farther-island structure, and headline wrecks like HTMS Khram. The dry season (November - April) brings the calmest seas and best odds of strong visibility, while May - October can be rougher and more variable. Most diving is day-boat based from Pattaya, with plenty of operators running regular two-dive trips. Add Sattahip and Samaesarn for a different flavor: managed island access and the WWII-era Hardeep wreck.
A nearisland reef day that works well for buoyancy practice, photography, and shorter surface intervals back in town.
Compact reef terrain with plenty of fish life and a good option when you want a lighter logistics dive day.
A rocky pinnaclestyle site where conditions can change quickly.
A farther island option that can deliver cleaner water and more openwater feel than the nearisland sites.
A Pattaya Far Islands wreck with ascent and descent lines, max depth around {{ 28 | distance:m }}, and its best visibility typically in the November March window.
A WWIIera steam cargo wreck in the Samaesarn area, resting around {{ 27 | distance:m }}, often attracting rays and dense reeffish clouds.
