The mountain is located in the northern area of the province of Nakhon Phanom.
Access to the trail and cave can only be done with a tour guide or special access park that is supplied by the national park staff.
It’s a tough 4km climb to the top of the mountain.
The whole trip takes almost 4 hours – longer if you’re not fit or want to take longer breaks at each location.
The Naga Cave is a popular tourist spot for Thais to visit – it’s also spelt ‘Naka’.
The rock formations have been sun-cracked due to the extreme day and night temperatures that caused the mountain rock to expand and contract.
Water eroded the edges of the cracks and resulted in the rock to look like snake scales.
The view from the top overlooks the Mekong River and the mountains of Laos.
The access trail for the cave begins at the park entry in Phai Lom, Ban Phaeng District, Nakhon Phanom
