Son Doong cave – World’s largest natural cave

Discovered in 1991 and officially explored in 2009, Son Doong Cave, nestled within Phong Nha-Ke Bang National Park in Quang Binh Province, Vietnam, has quickly captured international attention. Recognized as part of a UNESCO World Heritage site, it holds the title of the largest natural cave in the world.

What makes Son Doong truly extraordinary is its surreal, self-contained ecosystem. Inside, you’ll find an underground river, towering stalagmites, a dense jungle, and even its own localized weather system – an environment so vast it could house entire city blocks.

Strictly regulated to preserve its pristine condition, Son Doong offers a once-in-a-lifetime adventure, drawing explorers from around the globe to witness one of the Earth’s last great natural frontiers.

Note: There is no entrance fee to visit Son Doong Cave, but exploring it requires booking an all-inclusive tour organized by licensed operators. The tour must be reserved in advance and costs around $3,000 per person (4 days, 3 nights), including guides, equipment, porters, and safety support.

Phong Nha cave

Tucked away in the heart of Phong Nha – Ke Bang National Park, Phong Nha Cave is one of Vietnam’s most celebrated natural wonders and the first cave in the area opened to tourism. To reach it, you’ll drift along the serene Son River by boat – a peaceful journey that gently unveils the cave’s majestic entrance.

As you glide inside, a whole otherworldly scene appears: cool air, absolute silence, and a mesmerizing display of glittering stalactites and ancient rock formations sculpted over millions of years.

Recognized as part of a UNESCO World Heritage Site, Phong Nha Cave is not only a geological marvel but also a source of pride for the people of Quang Binh – and an unforgettable stop for any traveler seeking the soul of Vietnam’s wild beauty.

Entrance Fee

• Adults: 150,000 VND/person
• Children under 1.3 meters: Free

Note: A boat is required to reach the cave entrance via the Son River. The rental fee is approximately 550,000 VND per boat (maximum 12 people, including both adults and children).

Tien Son cave

Nestled just above the famous Phong Nha Cave lies Tien Son Cave, often dubbed the “dry twin” of its more watery sibling. Unlike Phong Nha, which is explored by boat, Tiên Sơn welcomes you with a climb and rewards you with a dazzling display of shimmering stalactites and stalagmites.

Stepping inside feels like entering a glittering palace carved by nature itself-towering rock columns, sparkling mineral curtains, and an almost mystical atmosphere that makes it feel like time stands still. Though smaller in size, Tiên Sơn’s beauty lies in its quiet, lesser-known charm, making it a must-visit for those looking to uncover the magical side of Phong Nha – Ke Bang National Park beyond the typical route.

Ticket price (reference):

• Adults: 80,000 VND/person/entry
• Children (under 1.3 meters): Free of charge

Hang En cave

Nestled deep within the Phong Nha – Ke Bang National Park, Hang En is the third-largest cave in the world and one of the most breathtaking hidden gems in Vietnam. Before reaching the legendary Son Doong, adventurers must pass through this magnificent cave, making it an unforgettable part of the journey.

What makes Hang En special isn’t just its size, but its surreal landscape: a massive cavern with towering ceilings, a natural campsite inside, and a sparkling underground river flowing gently through the cave. The entrance alone, framed by lush jungle and karst cliffs, is like a portal to another world.

The journey to Hang En is a true expedition – you’ll trek through dense forest, cross rivers, and pass remote ethnic villages before setting up camp right inside the cave.

Note: Hang En is free to enter, but independent travel is not permitted for safety reasons. You must join a 2-day, 1-night guided tour with camping inside the cave, costing around 7.6–8 million VND (~US$330–350) per person. Tours run from December to mid‑September with limited group sizes to preserve the environment.
