A Colourful Underground Adventure

If you’ve ever seen photos of Yangshuo, China, you’ve undoubtedly seen the iconic, mist-shrouded karst mountains rising vertically out of the Li and Yulong rivers. It looks exactly like a traditional Chinese watercolor painting come to life.

It is a unique landscape, formed over hundreds of millions of years through the slow chemical weathering of thick limestone deposits. The process began when the region was covered by shallow tropical seas during the Paleozoic and Mesozoic eras, allowing calcium carbonate from marine organisms and sediments to accumulate into vast limestone beds. As tectonic uplift later raised these layers above sea level, rainwater—naturally acidic from dissolved carbon dioxide—began seeping into cracks and fissures in the rock. This ate away at the rock, in a process known as karstification It carved the landscape into the region’s signature fenglin (isolated tower karst) and fenglong (cone karst) formations.

But what many travelers don’t realize is that these mountains – recognised by UNESCO for their unique look – are just as spectacular on the inside as they are on the outside.That acidic rainwater carved out massive, labyrinthine cave networks beneath the limestone towers. Today, visiting the Yangshuo caves is one of the most uniquely memorable (and wonderfully bizarre) adventures you can have in Guangxi.

Going Undergound

To start with you need to leave your expectations of “untouched, natural wilderness” at the cave entrance. In China, cave tourism follows a very specific, proudly theatrical philosophy: brightly coloured LED lighting.

Instead of casting dim, warm spotlights onto the rock formations, these caves are lit up like an underground synth-wave disco. Towering stalactites and curtain-like flowstones glow intensely in vibrant shades of magenta, electric blue, radioactive green, and deep violet. While purists might find it a bit shocking at first, if you embrace the pure, unapologetic kitsch of it all, it is incredibly fun and visually spectacular.

As the largest cave system in the Guilin area, Silver Cave runs directly through 12 different karst peaks. The cave gets its name because the mineral-rich stalactites catch the light and shimmer like silver and diamonds. You will walk through multi-story galleries alongside subterranean rivers that perfectly reflect the multi-colored light shows above.

The stories behind the name

There are two stories behind how the cave got named Silver. The most likely – and a popular explanation – is that the limestone formations glitter like silver when lit. But local folklore has a romantic tale to tell. During the Kangxi era of the Qing Dynasty, a defeated rebel army is said to have hidden in the cave, and to move on to safer ground they buried their treasure inside it before fleeing. That treasure has supposedly never been found, and no one knows for certain whether it’s real — but the legend gave rise to a regional saying that treasure hidden in Silver Cave brings fortune to people in Guangxi and Hunan.

Allow 1.5 to 2.5 hours for a visit. Inside temperatures remain relatively comfortable, around 20-26°C year-round, making it a good attraction during hot summer days (and Yangshuo can be VERY hot and humid in the summer). And a word of warning: paths are generally well developed, but some sections can be slippery, so sturdy footwear is recommended. No flipflops!

How to Get There

If you’re staying in Yangshuo, getting to Silver Cave (Yinziyan) is fairly easy. Silver Cave is about 18-27 km south of Yangshuo, near Maling Town in Lipu.

• Taxi or ride-hailing: About 30-40 minutes.
• Private driver/tour: Many Yangshuo day tours include Silver Cave.
• Tourist shuttle bus: Some tourist buses run directly from Yangshuo to Silver Cave.

If you’re in Guilin, Silver Cave is approximately 85 km from Guilin city.

1. Take a bus or train to Yangshuo, then continue by taxi.
2. Hire a private car directly from Guilin.
3. Join a Guilin-Yangshuo sightseeing tour that includes Silver Cave.
