Hat Sam Roi Yot (Hat Nom Sao), Prachuap Khiri Khan

White powdery sand stretches endlessly along this pristine coastline where Sam Roi Yot National Park meets the Gulf of Thailand. Hat Sam Roi Yot stands apart from Thailand’s crowded beach destinations with its wild, undeveloped character and dramatic limestone karst formations rising directly from the shoreline. Crystal-clear turquoise waters lap against the beach, creating perfect conditions for swimming and snorkeling in one of Thailand’s most unspoiled coastal environments.

Swimming here feels like having a private lagoon, with calm, shallow waters that remain comfortable year-round and excellent visibility for spotting tropical fish near the rocky outcrops. The sand stays cool underfoot even during midday sun, while natural shade comes from scattered casuarina trees lining parts of the beach. Fresh seafood vendors operate small stalls near the main access points, serving grilled fish and som tam salad with views across the water. Birdwatchers often spot white-bellied sea eagles soaring overhead, while the sound of waves mingles with calls from the diverse wildlife inhabiting the nearby wetlands and caves.

Tranquility defines the experience here, with visitor numbers remaining refreshingly low compared to Thailand’s famous island beaches. Gentle sea breezes carry the scent of salt air mixed with tropical vegetation, creating an atmosphere of complete relaxation. Early mornings bring local fishermen launching their boats, adding authentic charm to the peaceful setting without disturbing the serene ambiance that makes this beach special.

Cool season months from November through February offer the most comfortable weather, though the beach remains beautiful year-round with warm water temperatures. Getting here requires a short drive through Sam Roi Yot National Park, easily accessible from Hua Hin or Prachuap Khiri Khan town. Bring sun protection, drinking water, and snorkeling gear if you have it. The combination of pristine natural beauty and peaceful atmosphere makes this one of Thailand’s finest undiscovered beach experiences.
