Contrary to Longmen Cave, Guanyan is one of the best-equipped cave in Guilin. The cave contains 3 floors. The first floor is an underground river that's accessible only by boat, followed by an elevator that goes through a waterfall and leads to the second and the third floor. And then, a single-seat railcar will take you out of the cave and continue a little odyssey for 3 kilometres, and you can see the breath-taking landscape alongside the river coming towards you.

Relatively newly discovered by native villagers, the cave is extensive and unaltered, full of narrow, maze-like passages, and countless stalagmites. It is not advised to go without a guide, a crash helmet and a flashlight. The entrance is accessible only by boat and the whole trip would take approximately 2 hours. Near the exit of the cave, there is a mud bath onsen. However, given that the cave is not fully explored, the absence of certain security measurement exists. Thus going in alone is not recommended especially after 16h.

The hidden Lascaris War Rooms were Malta's best-kept secret during World War II. British troops used the underground tunnels and chambers as their headquarters to coordinate their fight against the Axis powers.
