Sai Kaeo Beach, Chonburi

Military-controlled Sai Kaeo Beach offers something increasingly rare along Thailand’s eastern coastline: pristine white sand and crystal-clear turquoise waters without the commercial chaos. Part of the Royal Thai Navy’s territory in Sattahip, this protected stretch maintains its natural beauty through restricted development and careful visitor management, creating an authentic beach experience reminiscent of Thailand’s untouched islands.

Fine white sand stretches for several kilometers, perfect for long walks while gentle waves lap the shoreline with a rhythmic whisper. The water clarity rivals Thailand’s most famous destinations, with visibility extending well into the deeper sections where small tropical fish dart between patches of seagrass. Swimming conditions remain excellent year-round, though the protected bay keeps waves minimal. Coconut palms provide natural shade along the beach’s length, while the sound of military aircraft occasionally punctuates the tropical tranquility. Basic food stalls operate near the entrance, serving fresh seafood and Thai favorites, though options remain limited compared to commercial beaches.

Peace defines the Sai Kaeo experience, with visitor numbers naturally controlled by its military location and restricted access hours. Families enjoy safe swimming conditions while couples find romantic sunset spots without aggressive vendors or loud music. The beach maintains an almost vintage Thailand atmosphere, where the primary sounds come from waves, wind, and seabirds rather than jet skis or party boats.

Cool season months from November through February provide ideal conditions with calm seas and comfortable temperatures. Public transport reaches Sattahip town, requiring a short taxi ride to the beach entrance where identification checks occur. Bring sunscreen, water, and snacks since amenities remain basic. The military setting ensures cleanliness and safety while preserving natural beauty that makes the journey from Bangkok or Pattaya worthwhile for beach purists seeking authentic coastal Thailand.
