Mount Bromo in East Java is an active volcano that feels more like a landscape from another planet. Its awe-inspiring Bromo Tengger Semeru National Park is defined by the vast Sea of Sand, a black volcanic desert surrounding the crater. 

Before you go, keep these essential tips in mind:

• Best Time to Visit: Aim for the dry season from April to October for the clearest skies and safest trails. The rainy season can bring fog that obscures the sunrise. Note that weekends and holidays get extremely crowded.

• Dress in Layers: Although Indonesia is tropical, temperatures at dawn on Mount Bromo can plummet to 0–10°C. A winter jacket, beanie, and gloves are essential.
