Brief Description

Composed of more than 17,000 islands and stretching over 5,000 kilometres (3,100 miles) from one end to the other, Indonesia is the world’s largest island nation and home to a diverse array of landscapes and scenery.

Situated between Southeast Asia and Australia, the archipelago is located right on the Paciifc Rim of Fire, meaning there are plenty of volcanoes and mountainous areas to explore. While the most popular mountaineering spots are on the island of New Guinea, popular climbing destinations are also found on Borneo and Java.    

Famous Mountains in Indonesia

While there are a number of memorable volcanoes and mountains in Indonesia, the most popular destination is the Carstensz Pyramid, or Puncak Jaya, as it is known by the locals. 

Rising to 4,884 metres (16,024 feet), the Carstensz Pyramid is the tallest mountain in Oceania/Australasia and therefore one of the Seven Summits. In spite of being the shortest of the seven, the Carstensz Pyramid is widely considered to be the most technically challenging, which, along with its remote location, is one of the reasons why it is the least climbed. 

Other popular expeditions in Indonesia are:

  • Climb Puncak Mandala
  • Climb Puncak Trikora
  • Climb Mount Semeru
  • Climb Mount Bromo
  • Climb Mount Rinjani

Quick Facts about Indonesia

  • Away from the Carstensz Pyramid, the island of Java is the most popular hiking and climbing destination in Indonesia. Two of the 38 peaks that run from east to west across the island – Mount Semeru and Bromo – are especially popular for hikers of all levels.
  • Due to its immense size and relative isolation of the various islands, Indonesia is an incredibly culturally diverse country, with more than 300 different ethnic groups and 700 regional languages.
  • Away from hiking and climbing, Indonesia is also famous for its beaches and wildlife, with millions of tourists coming each year to snorkel in coral reefs and visit the nature preserves, which are home to incredible rare endangered species.

How To Get To Indonesia

Most climbing and hiking trips to Indonesia will begin with a flight into Ngurah Rai International Airport (DPS), in Bali. Guides will generally opt to meet here and arrange transport to the start of the trip, which will usually include ferries or a series of domestic flights.
