Ijen Crater is also home to an acid lake that looks like most lakes but contains acid. It is said that you can try to put your hand in the acid lake for just a few seconds because if you are a little late, your skin can be damaged immediately.
Â
To prepare yourself to enjoy the climb and journey to Mount Ijen, don't forget to wear special climbing shoes, prepare drinking water, and wear thin, layered clothing that can be removed when descending. Also, wear sunscreen to ward off the hot sun when descending from the mountain. Most importantly, keep yourself safe and the environment clean during the trip.
