Welcome to Gunung Bagging, the independent guide to the mountains of Southeast Asia. Founded in 2009 in Jakarta, this non-profit project shares information on how to hike hundreds of peaks across Indonesia, Malaysia, Singapore and Timor-Leste (East Timor), and now much further afield. Everyone is encouraged to add their own trip reports as comments on mountain pages. Gunung Bagging is the birthplace of the Ribu concept (pronounced ree-boo - listen to audio file), defined as a mountain with a topographic prominence of 1000 metres or more, of which there are 7151 on Earth.

In 2025, Gunung Bagging expanded to cover all of Southeast Asia, adding reports and guides for mountains in Laos, Myanmar, Thailand, Vietnam, Brunei, Cambodia, and the Philippines. This more than doubled the project's geographical coverage and represented many thousands of hours of additional research and development.

As of June 2026, the project includes 743 individual mountains - 548 Ribus and 195 Spesials.

Gunung Bagging has always been a labour of love rather than a commercial venture. However, after more than fifteen years of largely unpaid work and despite repeated appeals for support, the project remains almost entirely unfunded. The costs of maintaining and expanding the website, undertaking field research, paying for the production of trail maps and writing new guides have been borne almost exclusively by the project's founders.

As a result, development is currently on hold. Existing writing will remain available and updates may still be added, but major expansion, new fieldwork and substantial improvements are unlikely in the near future without meaningful financial support.

Last month alone, Gunung Bagging received over 30,000 page views. Yet the level of financial support received has remained extremely low relative to the scale and value of the resource. Like many independent knowledge projects, the thousands of hours invested in creating and maintaining this archive are largely invisible.

If you have found Gunung Bagging useful, please consider supporting the project through a donation, Premium membership or partnership. Any contribution, however small, helps demonstrate that independent, specialist resources such as this are valued and worth sustaining for future generations of hikers, researchers and mountain enthusiasts.

For planning your trips, here are two updated resources:

An Excel spreadsheet with all the Southeast Asian Ribus and Spesials listed, along with elevation, prominence, region, plus latitude and longitude data.

A KML file with all the Southeast Asian Ribus and Spesials listed, for use with Google Maps or similar.
