All expeditions that we are currently offering will provide you with up-close encounters of the dramatic beauty of the Cave Kingdom of Vietnam. These world’s natural wonders are not to be missed and an expedition with Oxalis is guaranteed to be the best way to experience these magnificent places.
All Oxalis expeditions are led by experts from the British Cave Research Association, most notably Deb and Howard Limbert. They, along with local jungle men, were of the first to uncover this outstanding area and dive into the world’s most fascinating caves. Experts from the BCRA, along with an extremely knowledgeable and highly trained Vietnamese guide (who is fluent in English), will always be the leaders of Oxalis expeditions. They will be backed up by a reliable team, made up of a tour guide assistant and many porters. The porters are the best of the best of local jungle men—they are strong, hard working, and some of the friendliest people you will ever meet.
Oxalis strives to provide an unmatched experience in jungle and caving adventures, which is why we hire the best experts, tour guides, and porter team. We also ensure you that we use top-of-the-line safety equipment on all of our tours.
