Calling all cave adventurers! 📣 They call Phong Nha the "adventure capital of Asia," and it's easy to see why! There are endless caves just waiting to be explored! Including Son Doong, the world's largest cave! And Hang En, the third largest cave in the world. [Both Son Doong and Hang En have to be booked through @oxalisadventure, and they are worth every penny!] ✨See my Story Highlights for more adventures in Phong Nha on my page @drjennytravels #drjennytravels #phongnha #sondoong #hangen #phongnhacave #cavetrekking
