The beach is managed under the jurisdiction of the Royal Thai Navy's Marine Corps.
It is locally recognized as a 'conservation beach' due to strict environmental maintenance protocols enforced by the military.
The name 'Hat So' refers to the sound of pine needles blowing in the wind, characteristic of the trees lining the shore.
Hat So is a secluded coastal destination situated within the grounds of the Royal Thai Navy’s Sattahip Naval Base. It is characterized by its tranquil atmosphere, clear waters, and pine-shaded coastline. Unlike major commercial beaches, the area maintains a natural aesthetic with minimal shoreline development. The site features designated seating areas under mature trees that provide natural shade throughout the day. Access is restricted to those entering the military installation, ensuring a less crowded experience than public beaches in nearby Pattaya. The facility provides basic amenities including restrooms and small food kiosks operated within the naval complex. The shoreline is composed of fine sand suitable for wading and low-impact swimming.
