Southeast Asia is one of the most volcanic and mountainous regions of the world owing mainly to the make up of the Indonesian islands. In addition much of the region is limestone which is perfect for technical rock climbing.
Thailand is now a major rock climbing destination in the region with Krabi being the main focus with its hundreds of climbs at all levels. For mountain climbing, Borneo and Peninsular Malaysia are about the best in this department owing to the unique diversity of the landscape in the upper elevations and the sheer range of climbs.
Rai Leh - Krabi, Thailand
There are literally hundreds of superb climbs available on Rai Leh and neighbouring Ton Sai beaches in Krabi where numerous pocketed faces and overhangs are in evidence. The scenery is also beautiful to boot, plus Krabi itself has lots of other draws such as its beaches and nightlife.
Mount Kinabalu - Borneo, Malaysia
Mount Kinabalu is Southeast Asia's highest mountain at over 4,000m and the rock climbing and via ferrata walking here is superb. Climbs are available for all ages from beginner to advanced level.
Gunung Tahan, Malaysia
Peninsular Malaysia's highest mountain, Gunung Tahan, is the next best to Mount Kinabalu for those who don't have the time or inclination to make it over to Borneo. Many adventure companies offer long climbing treks up Gunung Tahan, traversing rainforests and rivers as well as mountain ridges.
Mount Rinjani, Indonesia
Remote Mount Rinjani is Indonesia’s second highest mountain outside Irian Jaya and offers great scope for adventure activities, including climbing. Mount Rinjani is volcanic like most other prominent mountains in Indonesia but is sadly shrouded in mist for most of the year.
Gunung Agung - Bali, Indonesia
Known locally as the 'navel of the world', Gunung Agung is the holiest mountain on the island and an active volcano. The Besakih temple sits on the mountain's 3,014-metre slope and the adventurous can attempt to climb it between July and October.
Batu Cave - Kuala Lumpur, Malaysia
One of Malaysia's biggest tourist attractions lies just outside of the capital and, although most people simply come here for a brief walk around the main chambers, there are some cracking climbs. More than 200 bolted routes are featured at the limestone Batu Caves with some stunning overhangs.
Fansipan, Vietnam
Vietnam’s highest peak is located in the remote mountainous north of the country and can be a bit of a trek to climb as it is fairly tough to access and takes around five days round-trip. The views are stunning, as is the abundance of wildlife, due to the fertility of the region and the lack of resident humans. Local trekking agencies in nearby Sapa can organize guides and supplies.
