Our one-day exploration of the park takes you to the heart of the "cave kingdom", a place blessed with natural beauty by Mother Nature. You will explore the primeval forests, a magnificent cave, and the underground rivers.

The journey begins with Commander Cave, located at kilometer 12 on Route 20 – Victory Road (Quang Tri), a natural cave about 150 meters long that was transformed by the Truong Son soldiers into a strategic base with seven levels, serving functions from first aid, logistics, and communications to combat command and daily living for officers and soldiers. During the resistance war against the United States, it served as the nerve center that coordinated the reception and transportation of thousands of tons of weapons and food to support the southern battlefield, while ensuring safety from bombs and shells thanks to its secluded and solid location. Today, Commander Cave has become a historical–ecotourism site, recreating the wartime atmosphere through models, artifacts, and virtual reality experiences, and is recognized as a symbolic historic site where visitors can truly feel the resilience and ingenuity of the Truong Son soldiers and people.

Become a real caver to explore the hidden wonder of nature, Nuoc Nut Cave, this cave is the last one in the cave system that includes Hang En, Son Doong, and Hang Va. It is formed by the Rao Thuong River, which originates from U Bo Peak, the highest point of the park. You will see the beautiful caves with large chambers, colorful stalactites, sandy beaches, and swim in clear emerald lakes. You will also explore the sparkling underground river inside the cave.

Detailed Itinerary

Please arrive in Phong Nha before 07:00 AM on the tour day to ensure a timely departure. 

From 7:00 to 7:30 a.m., the vehicle and tour guide will pick you up at your hotel in Phong Nha and transfer you to the Oxalis Adventure office. Here, you will receive a safety briefing, safety instructions, and an introduction to the tour itinerary.

To start off a day full of exciting activities, you will visit Commander Cave, a place that bears the footsteps of young soldiers and the memories of youth left behind in the Truong Son mountains amid the smoke and fire of war. Once a natural limestone cave, it was transformed by army engineers into a solid military base with seven distinct functional levels, closely tied to key strategic decisions along the Truong Son supply line. Today, visitors can explore each level of the cave, witness wartime relics, and relive the battlefield atmosphere through an immersive VR360 (9D) virtual reality experience.

After this meaningful visit to Commander Cave, the group continues by vehicle to the starting point of the trek to Nuoc Nut Cave. Following a short walk through dense forest and along easy trails, you will arrive at the cave entrance and have lunch here. Apart from a few shafts of natural light filtering through the ceiling, most of Nuoc Nut Cave remains shrouded in darkness.
