Son Doong Cave

Located near the Vietnam-Laos border, the cave was found by a local man named Ho-Khanh in 1991. The locals, it is said, were too afraid of the cave to go exploring because of the sound coming from the fast-moving underground river. In 2009, a group of scientists from the British Cave Research Association began an extensive survey of the cave's depths. According to Howard Limbert, the man leading the survey, the cave is five times larger than Phong Nha, which once held the title of the largest in Vietnam. The biggest chamber, his team found, is over five kilometers long and 200 meters tall. The jungle found inside of the cave has formed underneath a collapsed roof in one of the caverns. After the roof collapsed, enough light spilled into the cavern that vegetation was able to creep in slowly from outside. As the vegetation took hold, larger and larger plants began to grow.

Palitana

The Palitana temples are considered the most sacred pilgrimage place by the Jain community, and is the world’s largest temple cmplex with more than 3000 temples located on the Shatrunjaya hills, exquisitely carved in marble. Jainism is a relatively small religion, with only a little over 4 million believers in India and small pockets of followers throughout the rest of the world. The Jains' primary belief is non-violence; they believe that people, animals and even plants have souls and should be treated equally and well. Although they have no gods or spiritual figures, they do live with the principle of reincarnation in mind, hoping to eventually be liberated from the cycle of life and rebirth in an eternal transcedence. The Shatrunjaya Hill site is huge and pilgrimage rites are difficult for such an ascetic religion. The hill's 3,950 steps often take three hours to climb, with the elderly often hiring a dholi, a seat attached to a pole carried by strong men, to the top. It is the goal of devout Jains to climb the mountain 99 times in their lifetimes.
