The Travel website has listed Son Doong of Vietnam among the top 10 most incredible caves globally.

According to the website, caves are usually formed in one of four ways, namely by rainwater, wind erosion, volcanoes, or sand erosion. Boasting features such as geological formations, stalactites, stalagmites, and lakes, The Travel noted that caves are spectacular in many ways.

The website said that Son Doong, which can be translated as “River Mountain Cave”, is believed to be formed by the Rao Thuong River’s erosion into the base of a limestone mountain, Truong Son, causing a large tunnel to form underneath.

“Being 200m high and 175m wide as well as 9.4km in length, this cave is estimated to fit a 40-story New York skyscraper,” it noted.

The website added that one of the most fascinating parts of the cave is a thick forest mushrooming within the cave for years, as well as towering stalagmites, phytokarst, cave pearls, as well as the collapse of the cave roof.

The Travel also revealed that an expedition to the cave costs around 3,000 USD for four days via Phong Nha-Ke Bang National Park Management Board. Currently, tour activities are operated by Oxalis Adventure.
