The waterfall is overshadowed by Semeru, an active volcano and the highest mountain in Java. The Glidik River, which flows down Semeru, is the primary water source for the waterfall. Tumpak Sewu is loosely translated to mean "a thousand waterfalls" in the Javanese language.

The name likely originated due to its appearance of many different waterfalls in one single, semi-circular area.

Tumpak Sewu is a highly-visited tourist destination, primarily on the weekends. Infrastructure built around and inside the main box canyon has allowed for easier access to the area, although the trip to enter or exit is still physically demanding and may take around an hour to complete.

Just a 15 minute walk from the entrance ticket box and parking area is where your eyes are able to feast on the stunning aerial waterfall view of Tumpak Sewu. From the viewpoint, you will see a curtain of dewy white waters cascading down the rock face.

This consists of an observation deck where Tumpak Sewu Lumajang dreams are realised and you can witness this hidden treasure of Indonesia. Waterfalls like this are truly a once in a lifetime opportunity to see in person.
