Khao Yai national park has closed access to the park at the south entrance from Prachinburi province three hours earlier to alleviate confrontation between wild elephants and motorists. The south entrance at Nern Horm checkpoint in Prachinburi normally closes at 9 pm, but the checkpoint now closes at 6 pm. The closing time is moved forward after patrols by forestry officials on the route still encountered some wild elephants walking and crossing the route.
They were seen coming out of the jungles to the road heading for drinking water at Hellnarok waterfall, and also used the road to walk to a place where forestry officials has salinized soil land, about 2-3 kilometres off the road, for wild elephants to eat. Khao Yai national park chief Kanchit Srinoppawan said the park has already notified authorities of four provinces adjoining the national park areas, namely Saraburi, Nakhon Nayok, Prachinburi and Nakhon Ratchasima to inform tour companies and tourists about the time change.
