Wreck dives and day-trip reefs near Bangkok, with Navy-managed snorkeling in Sattahip
Overview
Pattaya is Bangkok's fast, flexible dive-and-beach escape on the Gulf of Thailand. Most divers base in Pattaya or Jomtien, then hop by boat to near-island reefs (Koh Larn, Koh Sak, Koh Khrock) or push farther to the Pattaya Far Islands for wrecks like HTMS Khram. South in Sattahip, the Samaesarn area adds a more nature-forward angle: controlled visitor numbers, clear-water snorkeling beaches, and WWII history on the Hardeep wreck. Expect warm water around 27°C to 30°C, variable visibility that improves offshore, and simple logistics for training, weekend dives, and mixed groups.
Pattaya is roughly 150 km from Bangkok, so it works for weekend dive trips and short stays.
The Pattaya Far Islands include day-boat wrecks like HTMS Khram.
Combine Pattaya's near islands with Sattahip and Samaesarn for a calmer, more regulated nature day.
Water temperatures are commonly around 27°C to 30°C.
