Why it matters
Why Batu Cermin Cave is worth your time
Mirror Stone Cave is a tunnel in a rock hill in West Manggarai, a few kilometres east of Labuan Bajo. Its walls sparkle in the morning light because they contain salt, thought to date from when the cave was underwater thousands of years ago.
Corals and marine fossils have been found in the walls, which supports the idea that the area was once submerged. For a family that has spent days on boats, the cave is a reminder that the landscape of Flores has changed and that the sea was once higher than today.

How to experience it
Batu Cermin means mirror stone, and the cave is a short walk through a hill of limestone. Most people go with a local guide who explains the formations and fossils. The most atmospheric time is the morning, when a shaft of light through the roof lights the walls and the salt crystals sparkle.
The passage is narrow in places, and you may need to duck under overhangs. Wear shoes with good grip, as the floor can be damp. Stay with the guide and do not touch the formations. If the weather has been wet, expect more slip risk.
The cave is close enough to town to combine with a lunch stop or a later visit to the harbour. It works as a gentle half-day when boats are not running, or as a rest from long boat days.
Plan with confidence
Small decisions that make the visit easier.
- Go in the morning for the light
- Wear shoes with good grip
- Carry a torch or ask the guide for one
- Skip if you dislike narrow spaces
