Heavy rain and flash flood risks have forced several national parks in Thailand to close or extend closures this month.

Here's where things stand:
● Khao Yai National Park: closed indefinitely
The park extended its closure on 27 September after flash floods destroyed the bridge leading to Haew Narok Waterfall, following several days of continuous heavy rain. Officials will assess the damage and inspect the bridge once conditions are safe. No tourists were injured or stranded, and the public is urged to avoid the area.

● Sai Yok National Park (Kanchanaburi)
Since 27 September, the service zone, Sai Yok Yai and Sai Yok Noi waterfalls, Lawa Cave, Daowadueng Cave, and camping areas have been closed until conditions return to normal and the sites are safe. Officials are closely monitoring Sai Yok Noi Waterfall and have set up sandbag barriers to reduce damage from falling trees and flooding.

● Phu Toei National Park (Suphan Buri)
Tourism and overnight stays have been suspended since 26 September due to heavy to very heavy rainfall. The park will stay closed until conditions improve and the area is safe.

● Khuean Srinagarindra National Park (Kanchanaburi)
Tourism and overnight stays have been suspended since 27 September after heavy rainfall and a thunderstorm-related power outage. The park will reopen once conditions return to normal and visitor safety can be assured.
