In March 2013, I had the opportunity to visit the world's largest cave, Son Doong cave in Vietnam. The karst caves I saw in Halong Bay were awesome, but at the Sondong Caves, I couldn't help but feel magnificent. To go to Son Doong Cave, we had to dig through more than 20 kilometers of jungle and camp. The pristine caves that reach hundreds of meters in height and with rivers flowing inside remain a big echo in my mind. It was a lot of expenses and a lot of trouble, but if I have a chance next time, it is a place I want to go again.
The world's largest cave expedition is in 2 episodes.
Thank you.
