The state has asked cavers and spelunkers to avoid caves which may be bat habitats.
The spelunkers climbed through rocky tubes 40m underground.
Two spelunkers discover an unexplored cave, but become trapped.
The cave has five different entrances and is rated by spelunkers as difficult for its narrow and flood-prone passages.
The section of the cave has a concentration of reddish maroon clay and features dozens of handmade sculptures, all formed and left behind by spelunkers.
It is popular for hikers, mountaineers, spelunkers and birdwatchers who come to explore its mountain trails, caves, odd rock formations and aviary.
Nevertheless, outside the caving community, spelunking and spelunkers predominately remain neutral terms referring to the practice and practitioners, without any respect to skill level.
