Oil Slick Impacts Koh Larn Beaches
An oil-like substance has washed ashore along a one-kilometer stretch of Koh Larn, affecting popular beaches and tourists.
On August 9, 2026, reports from Khaosod Online Thailand indicated that an unidentified substance, resembling engine oil, has washed up along the western coast of Koh Larn in Chonburi province. Local operators, including beach chair renters and speedboat captains, documented the contamination stretching over one kilometer across areas such as Tien Beach and Samae Beach.
Tourists swimming in the affected waters reported emerging with the substance on their bodies, necessitating immediate cleanup efforts. While the presence of the oil has caused significant disruption to beach activities, there have been no official reports of tourists suffering from allergic reactions or health complications related to the substance at this time.
In response to the incident, the Mayor of Pattaya, Poramase Ngampiches, has been notified and has ordered an official investigation into the source and nature of the pollution. For travelers and residents, this situation may impact plans for water activities in the area. It remains to be confirmed what the substance is, where it originated, and how long the cleanup process will take to restore the beaches to a safe condition. Visitors are advised to monitor local updates from Pattaya authorities before planning trips to the island.
