Overview

Wreck dives and day-trip reefs near Bangkok, with Navy-managed snorkeling in Sattahip

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.

What Makes It Special

  • Fast access from Bangkok

    Pattaya is roughly 150 km from Bangkok, so it works for weekend dive trips and short stays.

  • Wreck diving without a liveaboard

    The Pattaya Far Islands include day-boat wrecks like HTMS Khram.

  • Two-tone itinerary

    Combine Pattaya's near islands with Sattahip and Samaesarn for a calmer, more regulated nature day.

  • Warm water planning

    Water temperatures are commonly around 27°C to 30°C.
