Reed Flute Cave, Guilin

Guilin's Karst, Seen From the Inside

Reed Flute Cave (Ludi Yan) shows you what Guilin's famous peaks are made of. The same limestone that forms the karst towers along the Li River opens here into a 240-million-year-old cavern of stalactites, stalagmites, stone pillars, draperies and flowstone, all bathed in shifting coloured light. The name comes from the reeds that once grew thickly at the mouth of the cave, which locals cut and made into flutes. People have been coming a long time: more than seventy ink inscriptions survive on the walls, some over a thousand years old.

The undisputed star is the Crystal Palace of the Dragon King, a cavernous hall where a still pool reflects the illuminated formations above in a flawless mirror image; it is the photo everyone leaves with. Other named formations along the route, such as the "Pine in the Snow" and the "Virgin Forest", invite you to spot the shapes the rock and light suggest. The walk covers roughly 420 metres on a one-way path and takes about 40 to 50 minutes at a relaxed pace.

Opening Hours

The cave opens daily, with hours shifting by season: roughly 07:30-18:00 from April through October and 08:00-17:30 from November through March, with last entry around 30 minutes before closing (as of 2026). Hours can flex for holidays or maintenance, so confirm on site or with your hotel before you set out.

Tickets and Booking

Admission is a mid-priced single ticket, with the usual Chinese concessions: half price for eligible students and minors, free entry for the smallest children, and often a small discount for booking online rather than paying at the gate. Online tickets are real-name, so expect to enter a passport number and show the passport when you scan in. You can book through Chinese platforms or through English-language ones such as Klook; same-day online bookings usually need to be placed a couple of hours before you arrive.

Getting There

The cave sits in the northwest of Guilin, on the slope of Guangming (Bright) Hill, about 5-6 kilometres from the city centre. Bus 3 toward Changhai stops at Reed Flute Park, and bus 213 runs directly to the cave; a taxi or ride-hail from downtown takes roughly 15-20 minutes. Many travellers fold the cave into a half-day city loop with Seven Star Park and the riverside sights.

Best Season to Visit

Inside, the temperature stays cool and steady all year, which makes the cave a comfortable stop in any season and a genuinely refreshing one in Guilin's hot, humid summer (June to August). Spring and autumn give the best weather for pairing it with outdoor scenery. Avoid the early-October Golden Week if you can: the narrow passages queue badly.

Practical Tips

The route is one-way, so you move at the pace of the crowd around you; near opening time or in late afternoon you get more breathing room and cleaner photos. Flash struggles in the low light and tripods may be restricted, but the cave's own coloured lighting rewards a steady hand. Wear closed, grippy shoes for the damp paths and bring a thin layer for the constant cool air. Allow 40-50 minutes underground, plus time for the entrance plaza and gardens.
