Gawping into the halitosis mouth of Bromo felt a little redundant after I visited its bigger brother Ijen the following day and went right down its oesophagus.
Entering a volcano's crater was a predictably amazing experience, and like Yeliu in Taiwan and the mossy forest at Malaysia's Cameron Highlands, the weird and contradictory environment felt like being on an alien world.
An alien world that luckily had almost the same atmospheric composition as Earth, if perhaps a little heavy on the sulphur.
