Located on a rock formation just east of central Labuan Bajo, Batu Cermin Cave (Mirror Rock) gets its name from an impressive natural display that takes place inside. The tunnel-like cave carved into the dark stone of the island has a hole at the top, and for about an hour each day, the sun shines through the hole and reflects off the slick, mirror-like rock surfaces within.
Even when the light isn’t shining, visitors to Batu Cermin Cave can observe bats fluttering around inside, take in the panoramic views of the surrounding island or walk through the surroundings forests, where it’s possible to spot long-tailed monkeys and wild boars. You can hire flashlights from the rangers at the cave entrance, but they’re not always in the best condition, so consider bringing your own.
Batu Cermin Cave can be reached on foot or by taxi. The ride takes about 15 minutes while the hike is an easy 90-minute walk.
