Do you have mesmerizing electric blue fire, streaming down the mountain during the night, a turquoise, tranquil, but highly toxic lake with a sunrise that leaves you in awe with various shades of pink and purple as a backdrop, yourself being enrobed in sulphur clouds, breathing into a gas mask,making you look like a soldier on a mission and passing men carrying for hours up to 90 kilos of suplhur in baskets on their shoulders in mind when planning a hike in Indonesia?
Around the acid lake and on the crater rim you find miners selling figures made of sulfur (the small ones cost IDR 10.000 and the bigger ones IDR 20.000) to make an additional income. Frankly speaking, I have no idea what do with those objects (maybe a paper weight ?), but we all bought a few, as the hardship of those miners made us want to give a least a small token of appreciation.
This is the easy part (about 30 minutes of the 1 ½ hours total) up and down from the crater rim to and from the base camp. As you can see, this is really very manageable for even people not considered super fit.
