A rare natural phenomenon of vibrant green moss covering the rocks along Hua Hin Beach has captivated both local and international tourists, drawing crowds eager to capture the stunning sight. The moss, which appeared along a 12-kilometer stretch of coastline in Prachuap Khiri Khan Province, has transformed the shoreline into a picturesque landscape, particularly near the Centara Grand Beach Resort & Villas Hua Hin.
The moss-covered rocks, visible during low tide, create a striking contrast against the clear waters of the Gulf of Thailand. The long-stemmed moss clings tightly to the partially submerged rocks, forming a layered, emerald-green tapestry that has become a popular backdrop for photographs. Despite the slippery conditions, tourists have been seen carefully navigating the rocks to take souvenir pictures, while others enjoy the clear weather and calm seas.

Local officials and marine experts attribute the phenomenon to the area’s rich marine biodiversity, noting that such occurrences are a sign of a healthy ecosystem. The moss, which has been visible for approximately a week, is expected to dry up and disperse naturally in the coming days, returning the beach to its usual state.
The unexpected attraction has provided a boost to local businesses, with shop owners reporting increased foot traffic as visitors flock to the area. The phenomenon has also highlighted Hua Hin’s reputation as a destination for natural beauty, further cementing its appeal among travelers.
While the green moss has drawn widespread attention, authorities have assured the public that it poses no harm to humans or the environment. The event serves as a reminder of the region’s ecological richness and the ever-changing wonders of nature.
Among those present to witness the phenomenon were local officials, marine biologists, and tourists from around the world, all drawn to the unique spectacle.
