Top 10 Volcano Mountains in Indonesia to Climb

Although boasting 17,000 islands, Indonesia may come to mind with many islands, beaches, and seas, but you are surprised that it has just as many mountains. Being an archipelago situated at the confluence of the tectonic plates – Asian, Australian, Indian Ocean, and the Pacific Ocean, it has as many as 129 volcanoes making it the country with 13 percent of the world’s volcanoes. These volcanoes encircling the stretch of Indonesia have a name with an excellent ring – the Indonesia Ring of Fire.

The volcanoes, some active (some very busy) and some not provide a naturally stunning scenery unlike any other. Some mountains are within an immense volcanic lake, while others have craters that spurt blue fire.

The highest peak in Indonesia is the Puncak Jaya in Papua, while the largest volcanic lake is Lake Toba in Sumatra.
