Rangko Cave and Sand Island Labuan Bajo: A Hidden Gem in East Nusa Tenggara
This tour offers a chance to explore one of Labuan Bajo’s lesser-known treasures: Rangko Cave. At just $45 per person, it’s a compact 3-hour adventure that combines stunning natural beauty with a touch of adventure. Led by a knowledgeable guide—who was praised for making the trip unforgettable—you’ll hop aboard a boat and head to this secretive cave, which is best known for its peaceful blue pool and impressive stalactites.
What makes this experience stand out? First, the serenity of Rangko Cave’s secluded pool creates a feeling of discovering something truly special. Second, the chance to swim in cool, clear waters and relax on a fascinating sand island—subject to tides—adds a playful, spontaneous element.
A practical consideration? The tour is relatively short, so if you’re craving a full-day adventure or more extensive sightseeing, this might feel a bit limited. Also, the tour involves a brief, 5-minute climb to access the cave, which could be a hurdle for those with mobility issues.

The Journey to Rangko Cave
The highlight is the climb of approximately five minutes from the beach to reach the entrance, a manageable trek with rewarding views. The entrance is a small hole in the rock, which opens into a spectacular underground chamber. Once inside, you’re greeted with a tranquil blue water lake—the perfect spot for a quick dip. The water here is cool and refreshing, ideal after the climb, and the stalactites hanging from above lend an almost magical air to the space.
