Recently, Quang Binh has been in the spotlight with many discoveries of new stunning caves. Tu Lan Cave System is among these priceless discoveries. Located in Tan Hoa, Minh Hoa, Quang Binh Province, Tu Lan cave system comprises of 10 caves. It is estimated that Tu Lan’s formation started about 2 to 5 million years ago. They are of the oldest caves in Vietnam. Tu Lan is recognized as one of the most valuable natural complexes with a splendid beauty in Vietnam. It is no less imposing than the biggest cave in the world – Son Dong Cave which is also another wonder hiding in the jungle of Quang Binh. The wonderful thing about this cave is that even being discovered since 2009 with some adventure tours has gone into operation, it still remains untouched and primitive. These newly-discovered caves are not easy to access. It will be a sheer adventure full of surprise. To get into the cave, you would have to scale, climb and swim. It is also worth to notice that the tropical jungle will be really muddy and slippery. For most of the time, the only thing that lights your way is your headlamp. Each cave will give you a different experience. For example, in Son Cave, you will have to climb up to the top of the mountain to get to the cave door. From the cave door, you could enjoy the breath-taking horizon view of the valley. As the entrance is up to the top, to get to the cave floor, you will have to descend down with a ladder. Hang Tien (Tien Cave) will leave you speechless with the impressive sizes and enormous columns of limestone. On the cave floors, the water shapes the curving rock and made their way through.  Tien Cave 2 is even bigger. You will have to swim your way into the cave. One of the striking things that you could find in these cases is stalagmites and stalactites. The caves even have their own rivers and waterfall. If you want to explore the caves, you should expect a lot of climbing and swimming. The discovery will require strength and a body at its best. If you expect an easy trekking, this might not be a suitable choice. But you have a taste for adventure and new experience, you will absolutely love this place.
