Visit Rangko Cave
Rangko, north of Labuan Bajo, Indonesia
Rangko combines a coastal journey with a descent into a limestone cavern. After travelling to the village and taking a short boat ride, you walk through forest to reach the cave, where daylight falls onto a clear saltwater pool beneath rock formations. Plan the visit with a local guide who can judge the tide and access conditions. Wear footwear with grip for the approach and steps, and ask whether swimming is appropriate on the day.
