Ahead of the Thailand debut of "The Cave" documentary later this month.

You can now walk in the footsteps of the Wild Boar football team, who became an international sensation last year after being trapped in Tham Luang cave by heavy flooding for a nail-biting 18 days. Located in Chiang Rai’s Mae Sai district, the Tham Luang Nang Nom karstic cave system winds for 10.3 kilometers, while the boys were trapped around four kilometers in. Only the entrance, the first 260-foot chamber and the spirit house are now open to visitors, limited to 20 people at a time. Before entering, a permit must be obtained from the national park in which the cave is located. The move comes just before the documentary on the ordeal, “The Cave,” makes its Thailand debut on Nov 28 in Major Cineplex and SF Cinemas.
