Longgong Cave: China's Most Beautiful Water Cave & Karst Wonderland

Deep within the limestone mountains of Guizhou Province, a quiet river disappears into a cave mouth and re-emerges as a thundering underground waterfall. This is the heart of the Longgong Scenic Area, known in English as the Dragon Palace. Unlike the open-air power of nearby Huangguoshu Waterfall, Longgong offers a journey into the earth — a series of illuminated cave halls, subterranean boat passages, and a colossal cavern waterfall that ranks as the largest of its kind in China.

Situated 27 kilometers west of Anshun city center and only 30 kilometers from Huangguoshu, Longgong is a natural counterpart to Guizhou’s more famous waterfall. The entire scenic zone covers roughly 60 square kilometers of karst landscape, including dry caves, water caves, a whirlpool pond, and a rice-field calligraphic character visible from the hillsides. Though developed as a national 5A tourist attraction in 1984, the site retains a sense of geologic mystery, reinforced by local Buyi and Miao legends about a dragon king dwelling inside the mountain.

This article provides a practical guide to visiting Longgong, covering its major highlights, cultural context, logistical considerations, and how to decide if it fits your trip.

Why Go to Longgong (and When to Skip)

Longgong appeals most to travelers who enjoy underground exploration, photography of cave formations, and a quieter alternative to Huangguoshu. The core experience is a boat ride through a 5,000-meter underground river that passes through five large caverns. The boat moves slowly, allowing views of stalactites, stalagmites, and the massive Longmen Flying Waterfall that drops from a hole in the cave roof.

The site also features a natural Buddhist cave temple (Guanyin Cave), a spinning whirlpool pond, and a giant plant-based Chinese character planted by local farmers. These elements make it a diversified half-day outing suitable for families, independent travelers, and photographers interested in low-light cave photography.

Who Should Skip

• Travelers with limited mobility may find the boat ride accessible, but the cave paths involve steps and uneven surfaces.
• Anyone claustrophobic or uneasy about dark, enclosed spaces should consider whether the boat ride through narrow cave passages will be comfortable.
• If you have only one day near Anshun and want to see a single iconic waterfall, Huangguoshu is the more famous choice.
• Spring and autumn are recommended; summer (rainy season) brings higher water levels and stronger waterfall flow but also larger crowds.

Underground Wonders: The Water Caves

The Boat Ride Through the First and Second Cave Entrances

The centerpiece of Longgong is the underground river that runs through two connected cave sections. Visitors board a small flat-bottomed boat and glide into the “First Entrance” (Yijing). The cave opens into a hall illuminated by colored lights that reflect off limestone formations.

Stalactites hang from the ceiling like stone icicles; some resemble dragons, pillars, or palace columns. The boat continues through a low passage into the “Second Entrance” (Erjing), where the ceiling rises again and the Longmen Waterfall becomes audible.

The ride lasts roughly 20 to 30 minutes, depending on water conditions (exact duration not provided in source data). It is the highlight for most visitors. The boat ride is included in the entrance ticket for the water cave section.

Longmen Flying Waterfall: China’s Largest Cave Waterfall

Inside the Second Entrance, the boat approaches the Longmen (Dragon Gate) Flying Waterfall. With a drop of over 50 meters and a width of about 40 meters, it is the largest cave waterfall in China. Water pours from a hole in the cave roof, creating a roar that echoes through the chamber. In the rainy season (May to October), the volume increases significantly, and the spray can reach the boat.

Photographers should use a tripod or a fast lens because the lighting inside the cave is dim. The colored illumination changes regularly, so wait for a moment when the light on the waterfall is balanced.

Guanyin Cave: The Largest Cave Buddha Hall in China

Beyond the water caves, a separate dry cave complex houses Guanyin Cave. This is the largest natural cave Buddhist hall in China, containing a 12.6-meter-high statue of the Goddess of Mercy (Guanyin). The cave functions as an active temple; local pilgrims visit to pray, light incense, and make offerings. The atmosphere is quiet and contemplative, contrasting with the boat ride’s spectacle.

Accessing Guanyin Cave requires walking up a set of stairs from the main trail. The cave floor is level inside, but the approach is not wheelchair friendly.

Surface Attractions: Whirlpools and Field Art

Whirlpool Pond (Xuantang)

Outside the caves, a circular pond with a diameter of 101 meters rotates clockwise continuously. This geological oddity is caused by water draining into a funnel at the bottom, creating a natural whirlpool. Local legend says the Dragon King stirs the “sea eye” here. The pond is visible from a viewing platform; you can walk around it in about 10 minutes.

Dragon Word Field

On a hillside between the cave entrances and the parking area, farmers plant crops in the shape of the Chinese character for “dragon” (龙). In spring, rapeseed flowers create a yellow character against green fields; in autumn, rice turns golden. The character covers an area of several thousand square meters, making it the world’s largest plant-based Chinese character. The best view is from a designated observation deck near the upper parking lot.

Cultural Significance: Buyi and Miao Traditions

Longgong sits in an area historically inhabited by the Buyi and Miao ethnic groups. Before tourism development, local villagers considered the cave the sacred dwelling of the Dragon King — a deity who controlled rain and rivers. During festivals such as the “Soup Pot” (Guo Tang) festival and Miao New Year, communities gather near the cave to sing, dance, and perform the “Blocking Way Wine” ritual, where guests are offered a cup of rice wine before entering a village.

Though the scenic area is commercialized, you can still encounter these customs during festival periods. The ticket area includes a small ethnic culture exhibition. If you visit in late spring or early autumn, you may see performances organized by the park management.

Practical Information

Best Time to Visit

According to available source data, the best months are May through October. This corresponds to the rainy season, when the underground river is deep enough for boat navigation and the Longmen waterfall is at its most powerful. Spring and autumn offer mild temperatures; summer can be hot and humid, but the cave interior remains cool (around 18–20°C / 64–68°F). Winter is drier, and water levels may drop, but the caves are open year-round.

Suggested Duration

Half a day (3–4 hours) is enough to complete the boat ride, visit Guanyin Cave, and view the Whirlpool Pond and Dragon Word Field. Travelers combining with Huangguoshu should allocate one full day for both — start at Huangguoshu in the morning, then drive to Longgong in the afternoon.

Altitude and Safety

The scenic area sits at approximately 1,150 meters above sea level. This is not considered high altitude, and altitude sickness is unlikely. However, the caves are constantly damp and slippery inside. Wear sturdy, non-slip shoes. The boat ride is stable, but life jackets are provided. Flash photography may be restricted in some cave sections.

Ticket and Boat Ride

Entrance is paid. The boat ride through the water cave is included in the main ticket (exact price not verified in source data). There may be an additional fee for electric carts between the entrance and the boat dock; this is common at similar Chinese scenic areas.

Route Logic: Combining with Huangguoshu

Longgong is located 30 kilometers west of Huangguoshu. The drive between the two takes about 40 minutes by car or taxi. Most travelers staying in Anshun or Guiyang visit both on consecutive days. A typical two-day itinerary: Day 1 – Huangguoshu Waterfall (full day), Day 2 – Longgong (half day) plus an afternoon return to Anshun or Guiyang.

If you are driving, note that the road from Anshun to Longgong passes through rural Buyi villages. No special permits are required for foreign tourists.

Final Thoughts

Longgong earns its title as “China’s most beautiful water cave” through a combination of scale, variety, and atmosphere. The boat ride through the dragon-palace halls, the roar of the indoor waterfall, and the quiet Buddhist cave offer a diverse underground experience that complements Guizhou’s above-ground karst scenery. It is less crowded than Huangguoshu, making it a strong addition to any Guizhou itinerary — especially for travelers who want to go deeper than the usual waterfall photo stops.
