Incredible Formations

Son Doong is home to some of the most incredible rock formations on the planet, making it a must-see for geology enthusiasts.

Underground Rivers

One of the most fascinating aspects of Son Doong is the presence of several underground rivers. These rivers flow through the cave, creating underground lakes, waterfalls, and even beaches.
