The Caves

Paradise Cave

If you are short of time and only have the chance to see one cave, this has to be the one. A truly spectacular cave, the first 1 KM can be seen by anybody, either on The National Park Tours or by visiting the cave by yourself. The longer 7 KM trek into the cave is one of the most incredible days you can have in the area but is only available as a guided tour.  A real highlight of Phong Nha.

Phong Nha Cave

This was the first cave to be opened to the public and is seen by boat journey up the river from Phong Nha Village. It was used for shelter, as storage, and as a hospital during the American War, and there are still many scars from that time to be seen on its walls. It can easily be seen by yourself in half a day (we don’t run tours there), and is well worth a visit, especially for the journey in the traditional Dragon Boat up the river and through the cave.

Tra Ang Cave

A newly opened cave – Hang Tra Ang was only opened to the public in August 2016 and remains unspoiled by any touristic development. It is reached by a short walk through the dense jungle to a camp area before swimming into this cave to explore with a helmet, head torch and life jacket. Visited on The Phong Nha Jungle Boss National Park Tour and The Ma Da Valley Tour. A real highlight of Phong Nha.

Hang Voi (Elephant Cave)

A dry cave located in the heart of the protected zone of Phong Nha Ke Bang National Park. The cave is extremely picturesque as sunbeams bring the jungle growing inside this cave to life – highlighting this majestic cavern. It is a short challenging but none the less rewarding walk to the entrance. This cave is visited on The Ma Da Valley 1 Day and 2 Day Treks.

Hang Vom & Hang Gieng Vooc

A mixture of wet and dry caves first opened to the public in December 2018. Hang Vom is part of a cave system over 31 KM in length and is truly a sight to behold with its subterranean river and it’s spectacular rock formations, stalagmites & stalactites. These caves can be visited on either a 1 day tour and a very good value for money 2 day tour. A real highlight of Phong Nha.

Hang Toi (Dark Cave)

A real adventure cave, now very popular! There are no lights in the cave, and after zip-lining across the river, you swim through the cave with your head-torch leading the way, then explore a muddy side passage before kayaking back across the river. You can explore this spectacular cave on our National Park tour or independently. The other entrance to Dark Cave is many kilometers away in the Abandoned Valley and can be seen on the Abandoned Valley Trek. Hang Toi is a wonderful and very accessible example of the beautiful caves that are found throughout this region.

Tu Lan Caves

Single and multi day treks can be organised to this interesting cave system in the north west of Quang Binh province (outside of the National Park zone). Experience camping in the jungle with local bushmen in hammocks around a campfire. One of the main reasons that Tu Lan isn’t in the UNESCO world heritage area is that it was discovered so recently, and remains pristine for jungle adventuring and caving.

Hang Va

This spectacular cave has unique formations that we previously unknown in the caving world. There is still speculation about how they were formed. This newly opened cave is one for the adventurers and it is seen on a 1 night 2 day expedition that includes another cave called Nuoc Nut.

Hang En

One of the largest and most beautiful caves in the world, on the same system as Hang Son Doong (the world’s biggest cave) and as this cave is close as you will get with out the hefty price tag and huge commitment of going on a Son Doong expedition. To see this massive cave involves a day trek through beautiful jungle and valleys, and through a minority village, and then an overnight stay camping in the “entrance to Neverland” or on a beach inside the cave and then a trek back the following day.  A real highlight of Phong Nha.

Hang Son Doong

The world’s BIGGEST cave only discovered in 2009 and opened to tourism in 2014. There is a fascinating 45 minute documentary on the cave can be seen at This is a cave so big that a whole Manhattan city block, skyscrapers and all, could fit inside of it and it has immense and spectacular formations and dolines. The 4-day trek to the cave costs $3000/person. There is no other way to see Son Doong other than on the official trek, so if someone says that they will show you Son Doong, it is a scam, so beware.  A real highlight of Phong Nha.
