Xe Bang Fai Cave is the main attraction of Hin Nam No National Park. Villagers used to believe it was the source of the Xe Bang Fai river and the house of a benevolent spirit that would protect the villagers collecting swallow nests and bats inside the cave. The cave is almost 12 kilometers in length, some 76 meters high and 56 meters wide, and is considered to be one of the largest sustained river passages in the world, with enormous caverns decorated with highly impressive mineral formations and spectacular natural decorations.

The boat service group of Nong Ping village provides tours with paddle boats inside the cave for about 1h30, during which you can climb up one of the side chambers until you reach a balcony overlooking the entrance rocks.

For those looking for a more adventurous experience, Green Discovery travel agency provides tours through the full cave with inflatable kayaks, with the possibility of camping and trekking from/to the upper entrance.

When visiting the cave, you can stay in the brand new Nong Ping village campsite, in cozy bungalows or fully furnished tents next to the pristine river beach surrounded by limestone karsts.

The best way to access Nong Ping village and visit the Xe Bang Fai cave is to take a long-tailed wooden boat from Ban Pakphanang. Just sit back, relax, and enjoy a scenic one and a half hour journey through the Nam Phanang and Xe Bang Fai rivers surrounded by mountains, forests, fields, and water buffalos.

When traveling by motorbike, you can either park your bike safely in Ban Pakphanang (ask the boat driver first) and come back the same day or the day after to continue your adventure, or put your bike on the boat (one bike per boat) so you can enjoy the surroundings of Nong Ping village.

You can also reach Nong Ping by road, using the ferry service to cross the river and drive the remaining 30 km.

Mu Gia Pass is famous for being the principal entry point into Laos for the 16,000 km series of paths known as the Ho Chi Minh trail. It is estimated that 75% of all truck traffic carrying supplies from North Vietnam, destined for the Viet Cong revolutionary forces in South Vietnam, came through this narrow valley.

Nowadays, this pass is known as the Naphao/Chalo border checkpoint between Khammouane Province, Laos and Quang Bin Province, Vietnam.

The view from the Naphao border checkpoint road enables a spectacular panorama of the Ho Chi Minh trail. Imagine the noise of trucks struggling through the muddy valley below, the intense bombing, and the frenetic repairs to the road enabling traffic to continue along the trail virtually uninterrupted.

In this area, the landscape still bears witness to the unprecedented aerial bombardment, with bomb craters still visible after four decades.

Each villager who lived through the war here has a story of an epic struggle for survival that has remained largely unacknowledged.

Even if the testimonies of the past are becoming rare, you can still learn about the “Secret War” in these villages, on your way between Ban Langkhang (main road) and Ban Pakphanang (boat to Xe Bang Fai Cave).

Start from the border road where you can enjoy amazing views of the Mu Gia Pass and head to Ban Nongboua to visit nearby caves used for hiding during the war and enjoy a short trail to Tad Songsou waterfall.

Then visit Ban Phanop located at a ford on the Nam Ngo River. The legendary trail crossed through this village. The cobblestone-paved riverbanks and sections of road in the village attest to this. You can observe the remains of a crashed US warplane at the temple. This wing of the plane has been used as a billboard for the school for years during and after the war.

Head south to Ban Vangkhone to witness one of the most bombed areas of the Ho Chi Minh trail. During the war, the villagers moved 2 km away, next to caves. They came back to their village after the war, which is now overlapped with bomb craters that they use as fish ponds in the rainy season and to grow vegetables in the dry season.

Continue with Ban Senphan, where people are famous for their scrap metal collection skills. Even if they start selling this metal to Vietnamese to increase their small income, you can take a short walk in the village with a local guide and observe many relics of the war recycled: boats, planters, ladders, planks for houses… made of bomb and plane parts.

The presence of these objects is an ominous reminder that this area is likely to be littered with anti-personnel cluster bombs that are yet to explode. The work of organizations like UXO Lao, and humanitarian organizations like MAG, to disarm the countless dangers still lurking on the ground, goes on to this day.

From Ban Nongboua on the Ho Chi Minh trail, hire a local guide to take you to Tad Songsou at the base of Phou Cheuang Mountain, about half an hour from the village through the fields. This 20-meters high waterfall has water flowing all year round for a refreshing swim on your trip.

According to the local legend, its name comes from the fact that illegitimate couples would meet there, and one of them who had been discovered jumped from the falls to die together.

The Houay Ork stream flows through three caves upstream of Ban Thongxam, and there are different trail options from the village through the jungle and the limestone karsts.

These moderately difficult treks can take you to Pak Tham cave, a small cave filled with water, perfect for swimming, where locals say a giant shrimp lives in the deep pool at its entrance.

There is also a good view of Tham Pha Vao Cave, a very big cavity in the cliff-face.

The large branch of the cave with the skylight used to house about 3,000 North Vietnamese soldiers and local villagers during the war. Finally, reach the Nam Ork cave, the resurgence of the stream, where you can observe the impressive boulder ceiling and wildlife tracks in the sand.
