My humble and funny guide Kardi, who took me into the volcanic crater of Kawu Ijen, Eastern Java, Indonesia. The infamous site of blue fire.

He not only guides from 2am, taking tourists for sunrise, but after, will climb the crater again to mine the sulphur within and carry a 80kg+ load out by shoulder for a few extra dollars to feed his family.
