Welcome to the Gunung Bagging website, a non-profit initiative founded in 2009 in Jakarta, Indonesia. Here you will find information on how to hike hundreds of mountains across Indonesia, Malaysia, Singapore and Timor-Leste (East Timor) including trip reports, photographs, trail maps, practicalities and information on required logistics such as permits, guides and equipment. 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 7149 on Earth.

This year, Gunung Bagging is expanding its mountain coverage to all of Southeast Asia - not just Indonesia and Malaysia. That means new reports and regional guides for peaks in Lao, Myanmar, Thailand, Vietnam, Brunei, Cambodia and the Philippines. This expansion doubles the geographical area we cover.

As of early July 2025, the project includes 723 individual mountains - 548 Ribus and 175 Spesials - and that number is growing weekly. Behind the scenes, hundreds of hours are being poured into research, writing, mapping, and technical upgrades, all with very limited resources. We're also transitioning to a new GPS-enabled map system that will let users see their real-time location on mountain routes, a powerful safety feature for independent hikers. This work is a major undertaking and a passion project, but we can't do it alone. We urgently need your support.

If you find Gunung Bagging valuable, please consider contributing to help us keep it growing. One-off donations make a big difference, and for those who want to go further, we now offer Premium tiers and a unique partnership opportunity for organizations and serious backers. Your support will help us complete this transformation by September 2025 and bring better, safer and broader mountain coverage to the whole region. Please donate today via PayPal to co-founder Dan Quinn and be part of building something exceptional for Southeast Asia’s hiking and mountain communities.
