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), defined as a mountain with a topographic prominence of 1000 metres or more, of which there are 7149 on Earth.

In 2025, we are widening the coverage of Gunung Bagging to all of Southeast Asia. This means adding individual and regional reports for mountains in Lao, Myanmar, Thailand, Vietnam, Brunei, Cambodia and the Philippines. This represents a doubling of the geographical area we cover. Please bear with us as pages are created and populated over the coming months. This expansion is currently a work in progress, with many areas of the site under construction. This expansion will grow our readership significantly and offer many new possibilities for collaboration. As part of our development plans, we are now offering new Premium tiers plus an exclusive partnership opportunity. We also welcome one-off donations to support us to carry out this major expansion.
