Description
Rana Tonjong Lake is a unique freshwater lake located in Pota area, Sambi Rampas District, East Manggarai Regency, Flores Island, East Nusa Tenggara, Indonesia. Surrounded by rural landscapes, hills, and agricultural fields, this lake is best known for its extraordinary natural feature: giant floating water lilies and lotus-like vegetation that cover large parts of its surface.
Unlike typical lakes in Flores that are dominated by open water, Rana Tonjong presents a dynamic ecosystem where aquatic plants grow extensively across the lake, forming a floating green carpet. During certain seasons, especially around March to June, the lake becomes even more visually striking as the plants bloom, revealing beautiful flowers rising above the water surface.
The lake is located in a relatively quiet and less-developed tourism corridor in northern East Manggarai, which makes it a peaceful destination for travelers seeking untouched nature and authentic rural scenery.
Rana Tonjong is not only a scenic attraction but also an important ecological site that supports freshwater biodiversity, including fish, birds, and aquatic plants. The surrounding environment reflects the daily life of local communities who live in harmony with nature through farming and traditional rural activities.
For travelers exploring the hidden side of Flores Island, Rana Tonjong offers a rare and surreal landscape where water and floating vegetation merge into one living ecosystem.
