This spectacular volcano is a ‘husband and wife couple’ comprised of Lewotobi Perempuan (‘female’, 1703 metres) and Lewotobi Laki-laki (‘male’, 1584 metres). The peaks are often active – most eruptions have been from the Laki-laki vent, most recently in 2003, but seismic activity and minor volcanic emissions are common from both.
A Ribu is a prominent summit in Indonesia with at least 1,000 metre elevation drop all around. We have called them the Ribus because of the Indonesian word ‘ribu’ meaning a thousand. The variety of Ribus is huge; some are easy day-hikes near large cities; others are in remote and challenging environments and require weeks of travel and hiking to reach; some are active and dangerous volcanoes. The Ribus stretch across the Indonesian archipelago from Aceh in the west to Papua in the east.
There are four Ribu categories, three based on their absolute elevation and a fourth ‘Spesial’ category for peaks which are considered to be of special interest. Check the Methods page for more information on the analysis of prominence.
|Sangat Tinggi||Tinggi Sedang||Kurang Tinggi||Spesial|
Over 3000 m elevation
2000 to 3000 m elevation
Below 2000 m elevation
A special reason to bag it
There are currently 226 Ribus, plus 93 Spesial peaks. The ‘Spesial’ category has a number of uses. Firstly, Ultra prominent peaks in the Malaysian provinces of Sabah and Sarawak on the island of Borneo and the Timor Leste part of Timor island are included here. Other Spesial Ribus are deemed of particular interest. For example Anak Krakatau is a mere 324 metres high, but is a Spesial because of its volcanic activity and great historical interest.
‘Bagging’ is an informal term which means ‘collecting’. Hill and mountain bagging is very popular in Great Britain, and there are numerous list for different countries and counties. The great thing about lists is that they offer an incentive to get out there and visit places you might not normally think to go.

This site provides a comprehensive list and classification of prominent mountains in Indonesia, which we call “The Ribus”. We hope the site inspires you explore Indonesia’s many mountains and volcanoes and prioritise which peaks to climb.
You can browse the Ribus by category or by province and view Google Maps showing their distribution. In our Resources section, we also have a growing database of Guides and GPS tracks. Share your experiences by posting comments and trip reports.
