When people imagine caves, they often imagine them as a big hole in the ground or mountain. However, most caves in Central Vietnam are actually part of cave systems; networks of caves, channels and chambers, and the Tu Lan Cave system is a perfect example of this.
There are 1 day, 2 day, 3 day and 4 day tours to the Tu Lan Caves, which give some idea to how expansive they are, and how much there is to see. Some of the caves to be seen on these tours are Ton Cave, Ken Cave, Kim Cave, Tu Lan Cave, Chuot Cave, Tien Cave, Uoi Cave, Ruc Cave, Secret Cave, Doi Cave, and To Mo Cave. None of them are huge, but to explore this cave system involves trekking through the jungle, trekking and swimming through caves, river crossings, jungle campsites and so much more, so the experience is varied and a lot of fun.
