These intriguing geographical facts of Indonesia begin with its tallest mountain.

Mount Carstensz in the Sudirman Range is the tallest mountain, but it consists of a range of peaks reaching up to just under 5,000 meters.

Whilst Puncak Jaya is the highest peak, summits like Ngga Pula and East Carstensz Peak fall just mere meters below their bigger brother.

From a distance it actually looks more like a supersized cliff face than a mountain.

Java is by far the most populous island, whilst also taking the title of being the most populated island on the planet.

A grand total of 135 million people live on Java.

It’s also home to Indonesia’s largest city and capital, Jakarta.

The eruption wiped out most of our ancestors and a multitude of Indonesia’s islands were created in the process.2
