After a wonderful night in the ranger station at the foot of Kawah Ijen we climbed up the mountain to have a look at the famous crater lake. On the way up we had a wonderful view at
Raung, another very active stratovolcano.
The ranger station below is far away from the cities. There is only a small generator with normally limited fuel supplies. When we were there electrical power was available till we finished our dinner. Afterwards only the petrolium lights spent some light. The night sky was breathtaking. Without any spam light from the cities even the faintest star came out to show itself on the interstellar catwalk.
