What Oxalis does
Oxalis Company Limited, operating as Oxalis Adventure, is a privately held Vietnamese adventure tourism company founded on June 8, 2011, and headquartered in Phong Nha, Quang Tri Province. The company specializes in multi-day cave exploration and jungle trekking expeditions within the UNESCO World Heritage-listed Phong Nha-Ke Bang National Park and Tu Lan Cave System, with a portfolio of 16+ tour products ranging from single-day introductory trips (VND 2,000,000) to the flagship six-day Son Doong Cave Expedition priced at USD 3,000 / VND 79,500,000 per person. Oxalis holds the exclusive operating license from the National Park Management Board to conduct tours into Son Doong, the world's largest cave, and partners with Howard Limbert and the British Vietnam Caving Expedition Team for technical and safety expertise. Safety systems use international-standard caving equipment from France, Switzerland, and the UK, supported by satellite communications, professional safety assistants, and a 3:1 staff-to-guest ratio on premium expeditions.
The company's business model is direct-to-consumer: customers book tours via oxalisadventure.com with included pickup from Dong Hoi airport or train station, on fixed departure dates for individuals or private departures for groups and media. Conservation-mandated annual caps (1,000 Son Doong, 500 Hang Ba, 600 Tu Lan guests) act as both a regulatory constraint and pricing-power mechanism. Vertical integration extends to five owned accommodation properties (Chày Lập Farmstay, Blue Diamond Retreat, Tú Làn Lodge, Oxalis Home, Commander Lodge) and a wholly owned safari subsidiary, Katien Safari, which operates wildlife tours in Cat Tien National Park. Additional revenue lines include a Son Doong 5D VR experience at the Phong Nha Caves Exploration Museum and customized corporate team-building programs.
Oxalis employs over 500 local staff from Phong Nha and Tan Hoa communities, many of whom transitioned from illegal logging and hunting into sustainable tourism employment. The Oxalis Foundation funds community programs including free swimming and safety training for over 300 children annually, and the company reports it has helped reduce poverty in Tan Hoa village from 85.7% in 2010 to 2% in 2024. Operational certifications include International Travel Business License No. 44-002/2014/TCDL-GPLHQT issued by the Vietnam National Administration of Tourism. The customer base is geographically diversified global adventure travelers aged 18-70, with secondary segments including conservation-focused tourists and families; UOB cardholder and returning-guest (Xiều) discount programs support retention.
