A multi-stream semicircular waterfall formed by Mount Semeru's volcanic erosion, known for its canyon trail and panoramic viewpoint with Semeru backdrop.

Tumpak Sewu, which translates to 'A Thousand Waterfalls' in Javanese, is one of Indonesia's most spectacular waterfall formations. Located on the border between Lumajang and Malang regencies, this horseshoe-shaped waterfall cascades down a volcanic cliff face in hundreds of individual streams, creating a breathtaking natural curtain of water. The waterfall is fed by the Glidik River, which originates from the slopes of Mount Semeru, Java's highest and most active volcano. The panoramic viewpoint offers a stunning perspective with Semeru often visible in the background, especially during sunrise. The descent to the waterfall base involves navigating bamboo ladders, ropes, and rocky paths, making it an adventurous experience. Locals refer to Tumpak Sewu as 'Semeru's Breath,' representing the continuous flow of life from the volcano to the earth below.

Cultural Significance

"Tumpak Sewu holds deep significance for the local communities who view the waterfall as 'Semeru's Breath' - the physical manifestation of the volcano's life force flowing to the earth. The continuous flow of water symbolizes renewal, humility, and the natural cycle of life. While less explicitly ritualized than other sites, the waterfall represents the power and generosity of nature in local cosmology. The name itself, 'A Thousand Waterfalls,' reflects the Javanese appreciation for nature's abundance and complexity."
