Phong Nha-Ke Bang is Vietnam's cave capital — Son Doong (world's largest cave), Hang En's jungle trek, Paradise Cave's formations, and Phong Nha Farmstay's boutique eco-lodge on the Son River. Our guide covers the top properties and how to book the world's most exclusive cave expedition.
Phong Nha: Vietnam's Cave Capital
Phong Nha-Ke Bang National Park is a UNESCO World Heritage Site in Quang Binh Province, central Vietnam — home to the world's largest cave system, including Son Doong (the world's largest cave by volume) and Hang En (the world's third-largest). The park's 123,000 hectares of karst limestone contain over 300 caves, ancient forest, and some of Vietnam's most extraordinary underground landscapes.
The luxury accommodation scene in Phong Nha has developed significantly. Phong Nha Farmstay (the original boutique property), Chay Lap Farmstay, and a collection of eco-lodges offer genuine quality in a destination that rewards slow exploration.

- Cycling: Bicycles available for exploring the surrounding countryside and cave entrances.
Phong Nha's Caves
Son Doong (World's Largest Cave)
Son Doong is the world's largest cave by volume — large enough to contain a 40-story skyscraper. The 4-day expedition (the only way to visit) is run exclusively by Oxalis Adventure Tours and costs $3,000+/person. Only 1,000 permits are issued per year. According to National Geographic's cave exploration coverage, Son Doong is one of the world's great natural wonders.
Hang En (World's Third-Largest Cave)
Hang En requires a 2-day trek through jungle and river crossings — the cave contains a beach, a lake, and a massive chamber with a natural skylight. Oxalis runs the only permitted tours ($300+/person).
Paradise Cave (Thien Duong)
The most accessible major cave — a 31km cave with extraordinary stalactite and stalagmite formations. A 1km boardwalk allows visitors to explore the cave's main chamber without a guide. The most visited cave in the park.
Phong Nha Cave
The original cave — accessible by boat on the Son River. A 1.5km boat journey through the cave's river passage, with impressive formations. Less dramatic than Paradise Cave but historically significant.
Dark Cave (Hang Toi)
An adventure cave — visitors zipline into the cave, swim through underground passages, and kayak through the darkness. One of Vietnam's most exciting adventure activities.

Frequently Asked Questions
Do I need to book Son Doong in advance?
Yes — Son Doong permits are extremely limited (1,000/year) and sell out months in advance. Book through Oxalis Adventure Tours (the only licensed operator) as early as possible — ideally 6–12 months ahead for peak season.
Is Phong Nha worth visiting without Son Doong?
Absolutely — Paradise Cave, Hang En, and Dark Cave are all extraordinary experiences. The landscape around Phong Nha (karst mountains, Son River, jungle) is beautiful, and the Phong Nha Farmstay is one of Vietnam's finest boutique properties. A 2-night stay without Son Doong is still exceptional.
How far is Phong Nha from Hue?
160km south — approximately 2.5 hours by road. Many travelers combine Hue and Phong Nha on a central Vietnam itinerary, stopping at the DMZ (Demilitarized Zone) en route.
