Scuba

What It Feels Like

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.

Signature Sites

Start Here

  • Koh Sak

    A nearisland reef day that works well for buoyancy practice, photography, and shorter surface intervals back in town.

  • Koh Khrock

    Compact reef terrain with plenty of fish life and a good option when you want a lighter logistics dive day.

  • North Rock/ Lom Fang

    A rocky pinnaclestyle site where conditions can change quickly.

Level Up

  • Koh Rin North

    A farther island option that can deliver cleaner water and more openwater feel than the nearisland sites.

Advanced

  • HTMS Khram

    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.

  • Hardeep Wreck (SS Suddhadib)

    A WWIIera steam cargo wreck in the Samaesarn area, resting around {{ 27 | distance:m }}, often attracting rays and dense reeffish clouds.

Planning Playbook

Operator Checklist

  • Book far-island trips early in your stay, so you can swap days if weather turns.
  • Ask operators about tides and pick higher-tide windows for the best odds of visibility.
  • Expect boat traffic around popular islands. Use an SMB and do controlled ascents.
  • If you are prone to seasickness, far-island rides are the day to medicate early.
