Difficulty Mount Semeru Indonesia - Terrain

Summits Index:
5 / 10 (Mild difficult)

Black puffy clouds of volcanic ash and sand are released from the peak almost on an hourly basis. The only inconvenience you may face is the wind and rocky terrain you’ll encounter before you get to Ranu Kumbolo. The route could also get a little confusing at times due to the occasional tree and the formation of clouds.

The climbing terrain is comprised of two sections: the pre-summit section that needs to be covered on Day 1 has mostly vegetable plantations and pine forests. One may need to be careful about the monkeys in this region.

The summit section is comprised of mostly hardened lava-based rocks with little vegetation. The trail becomes more difficult as it gets steeper and the loose terrain could lead to slips if trekkers aren’t careful.

There is an alternate route that takes one through the fields back to the village of Ranu Pani, which is rarely attempted and may require one to hire a guide, especially for first-timers.
