Indonesia is an archipelago of more than 17,000 islands spread along the Pacific Ring of Fire, making it one of the most volcanically active countries in the world. The highest mountain is Puncak Jaya in New Guinea, reaching an impressive 4,884 metres, making it one of the highest peaks in all of Asia and the Pacific. The volcanic massifs of Java and Sumatra offer dozens of accessible craters and peaks – among the best known are Semeru, Bromo and Rinjani on Lombok, whose caldera with a mountain lake ranks among the most beautiful volcanic landscapes in the world. Dense tropical jungle, dramatic mountain ridges and countless trails make Indonesia an exceptional destination for nature lovers and adventurers seeking peaks off the beaten track.
