Hang Sơn Đoòng

Epic in all respects, you can only come here with Oxalis Adventure Tours and it will cost you USD 3000 and you will need to book at least a year in advance. Probably the best money I’ve spent on any trip, particularly when you take into consideration the logistics of such an expedition, 30 plus staff to ten participants. The company is incredibly professional, food is restaurant quality and they have a strong commitment to local communities and environment. It is everything you’d expect from the world’s largest cave and a USD 3000 commitment, worth every cent, you simply can’t come close to this experience on any other cave trip. You will need a high level of fitness, coordination and reasonable confidence.

It was so beautiful, my first experience here & really it was breath taking. Nature has its own beauty to show us very beautiful stuff. The lake, the mountain, it's soooo peaceful.

Without a doubt, the best experience I had in my life. I’ve been all around the world and this place left such an impression on me and will for a really long time. H’Anetta (our tour guide) was very professional, fun, passionate, and very knowledgeable. On top of that, the porters and safety assistants were also spectacular and further enhanced our experience. they were incredibly helpful and the most kind hearted people. There were 3 campsites and each one of them had its own character. Waking up to the view is to die for, sometimes it felt like I was on another planet. The trek was challenging but also very fun, plus the safety assistants are, again, very helpful. There was a great balance between going through caves and jungles. And occasionally, you’d cross rivers too! Overall, reconnecting with nature was a success 😎

Hang Son Doong Vietnam's Hang Son Doong, the largest cave in the world could hold an entire city block of Manhattan—including 40-story skyscrapers. It has its own lush vegetation where sunlight filters in from sinkholes above, and clouds even form near the ceiling when moisture condenses there. In other words, it's practically its own little world lurking under the earth's surface. 📍Vietnam

Perfect stop when visiting Halong Bay. The cave is amazing.

It was an amazing adventure of a lifetime. The whole expedition was well executed by a team of professional crews from Oxalis. They make the seemingly tough maneuvering through the deep jungles, never ending terrains, rocky mountains, thrashing waterfalls for city dwellers like us to be able to cross each of these hurdles readily, with their full support of safety officers at arms length.

Son Doong Cave, located in the Phong Nha-Ke Bang National Park in Vietnam, is an awe-inspiring natural wonder and the world's largest cave by volume. Inside, you'll find unique ecosystems, including lush jungle landscapes, fast-flowing rivers, and towering stalagmites and stalactites. The cave's sheer scale and unspoiled beauty offer a surreal experience, making it a must-visit for adventure seekers and nature enthusiasts alike. Exploring Son Doong Cave is a challenging adventure due to its remote location, demanding terrain, and technical requirements. The journey involves multi-day hikes through dense jungle, river crossings, and steep climbs, all requiring a good level of fitness and stamina. Inside the cave, adventurers face harsh conditions such as high humidity, slippery surfaces, and temperature variations. Access is limited to guided tours with experienced caving experts, and the cave's isolation means that medical facilities and emergency services are far away, adding to the risks involved. Overall, Son Doong is a breathtaking and humbling destination that showcases the incredible power and beauty of nature, a MUST visit once in a life time place ☺️☺️☺️☺️
