Rangko Cave is a hidden natural gem located on Flores Island, Indonesia, featuring a saltwater pool inside. The water in the cave is incredibly clear and sparkles when sunlight filters through, creating a mesmerizing visual effect. The cave’s walls are adorned with stalactites and stalagmites, adding to its natural beauty. This cave offers a unique swimming experience in a magical and secluded setting, far from tourist crowds.

To reach Rangko Cave, you first need to travel to Labuan Bajo. From there, you can rent a small boat or join a tour to cross the sea to Rangko Village, where the cave is located. The boat ride takes about 30-45 minutes, and once you arrive in the village, you’ll continue on foot for about 10-15 minutes to reach the cave. Make sure to bring drinking water and wear comfortable footwear, as the path to the cave is rocky.

The best time to visit Rangko Cave is during midday, around 12:00 to 14:00. At this time, sunlight streams into the cave through an opening above, illuminating the pool with beautiful light, creating a stunning bright blue effect in the water. Be sure to plan your visit to arrive at the cave during these hours for the most breathtaking experience.

Before entering Rangko Cave, make sure to bring your swimming gear, as you’ll likely be tempted to swim in the crystal-clear saltwater pool. Since the cave has no public facilities, it’s advisable to bring personal items like a towel, non-slip sandals, and drinking water. Don’t forget to bring a flashlight or headlamp, as while the front of the cave is well-lit, the interior can be quite dark.

Inside Rangko Cave, the environment is quite humid and slippery, especially around the pool. The cave walls, adorned with stalactites and stalagmites, require caution as you move around. The pool’s water is calm, clear, and cool, making it an ideal place for a refreshing swim. Although the cave is fairly spacious, there isn’t much room around the pool for sitting or standing, so you may find it more comfortable to spend your time in the water.
