Rangko Cave is an amaging cave located in Rangko Village, Boleng District, West Manggarai Regency, East Nusa Tenggara, Indonesia. This cave is famous for its natural saltwater pool inside, providing a unique swimming experience in a cave with clear, turquoise water.
Rangko Cave has beautiful stalactite and stalagmite formations, creating a magical and stunning atmosphere. The sunlight that enters through the gaps in the cave creates a dramatic lighting effect, especially during the day when the sunlight penetrates directly into the pool, making the water appear to glow and radiate its blue color even more.
One of the main attractions here is the saltwater pool inside. This pool has clear and calm water, with a depth that is safe enough for swimming. Because the water is salty, visitors can float easily, similar to the experience of swimming in the Dead Sea. The water in this cave comes from seawater seepage that enters through the gaps in the surrounding limestone rocks.
To reach this destination, visitors must travel by boat from Labuan Bajo to Rangko Village, which takes around 40–60 minutes. From Rangko Village, the journey continues on foot for around 10–15 minutes along a path to the cave entrance. The terrain is quite easy to traverse, but it is still advisable to wear comfortable footwear.
The best time to visit this cave is around 12.00–15.00 WITA, when the sun is at its highest. At this time, sunlight enters directly into the cave and illuminates the pool, providing an incredibly beautiful visual effect.
Rangko Cave is the perfect destination for nature and adventure lovers who want to enjoy the beauty of an underground cave with a stunning natural pool. The uniqueness and charm of this cave make it one of the hidden tourist attractions that must be visited around Labuan Bajo.
