Climbing Mount Agung Indonesia - Geological history

Located in the district of Karangasem, in north-eastern Bali is the island nation’s higher mountain - Mount Agung. Standing 3031 metres above the sea level, it is believed to be the home of the Gods by the Balinese who revere it deeply. It is also the fifth highest volcano in Indonesia. After almost a century in sleep, it erupted in 1962, leading to the most fatal volcanic event in Indonesian history with 15,000 being killed. Even though geologists had considered it not to be a threat anymore, it has been volatile even up to this year. It’s now said to be in ‘deflation mode’ and there is a Level 3 warning issued, meaning no climbing beyond a 4km radius from the crater - the whole summit, for all intents and purposes.

Climbing Mount Agung Indonesia - Modern climbing history

Being home to Bali’s Hindu mother temple – the Besakih temple, which is located in the west of the summit – Mount Agung, until very recently, saw Hindus and several pilgrims from Asia and beyond trek to the summit daily, to offer their prayers. Being a demanding yet unforgettable climb, Mount Agung has always been a favourite of visitors - since the 14th century to the present day. Most tourists choose the guided day trip package (bargaining is usually involved). The climb is serious, arduous and involves some risks that can be avoided by using the right clothes and gear. Climbers avoid Mount Agung in January and February as it is very wet. The northern ascent route will need you to camp too.

Climbing Mount Agung Indonesia - Current popularity as a climbing destination

Despite its violent history and recurring eruptions, Mount Agung is still a crowd-pleasing mountain that is often climbed by locals and tourists. Around 30,000 people gather every year to summit the mountain due to its popularity and relatively accessibility (before it started erupting again, the caldera was reachable by road). Among all the trails, one from Besakih is the safest and opted by most. No one climbs the mountain in April as religious ceremonies are held then.

Climbing Mount Agung Indonesia - Overall Assessment

Climbing Mount Agung Indonesia - Summary of trail accessibility

Expert mountain climbing skills or specialised equipment is not necessary for climbing Mount Agung. The climb will take anywhere from 7-12 hours depending on the trail. Most trekkers of good fitness levels will be able to tackle the climb. However, trekkers with prior training and dedication would more efficiently be able to tackle the higher altitudes and demanding terrains of dense rainforests and desolate volcanic rock landscapes. The route from Besakih to the summit is especially challenging in the last hour, where you might have to climb on all fours.

Climbing Mount Agung Indonesia - Trail options

Number of options

There are 3 different trails to choose from depending on the experience, fitness level and preference of the climber. Climbers wishing for a shorter (yet more demanding) trek taking 3-6 hours can opt for options 1 or 3 whilst climbers looking for a longer but less physically demanding trek can opt for option 2 (this trail takes 10-12 hours).

Walking distance of this trail is approximately 23 km. This trail takes 5-6 hours to complete (with the final hour being the toughest) starting from Besakih temple to the west of the summit. The climb is demanding yet doable for amateur climbers with determination. During the last hour of the route, the terrain is notably rough, often forcing climbers to reach the summit on all fours.

This is the longest yet less physically demanding route starting from the north of the summit and is known to take 10 – 12 hours. This route is mostly recommended for less technically experienced climbers. It starts from 300m altitude and involves a necessary overnight camp at 1700m. Climbers can walk around the crater rim by following this trail.

Walking distance of this trail is approximately 8 km. This is the shortest yet most physically demanding trail starting from the south of the summit and it takes climbers an average of 3-4 hours to complete. This route firstly takes climbers though steep, dense rainforest. The rainforest gradually gets less dense and transitions into a desolate landscape of rocks and boulders. The final leg of the route is a steep slope which finally leads climbers to the top of the mountain.

Starting from Besakih temple (West)

Climbing Mount Agung Indonesia - Standard itinerary

Number of days

The climb from the Besakih temple is the most popular one at present, though it is quite challenging. It takes 6 to 7 hours for the climber to arrive at the summit, and the trek usually begins at 11pm so that you can reach the top in time for sunrise. One can also start at 4am and come down from the summit before the night sets in. The reason for this trail’s popularity is that the trail from Pura Pasar Agung Temple is dangerous, strewn with slippery rocks. Solidified lava, sharp rocks and fog add to the risk. The route from Duku Bujangga Sakti is also rarely used and adequate information on it is lacking.

The terrain of Mount Agung can be split into 2 distinct sections: the terrain of lower altitudes is mainly tropical forest, whereas the higher altitudes and summit mostly consist of rocks and less vegetation.

Climbing Mount Agung Indonesia - Rainforest at low altitude of 1500m
From the beginning of the ascent climbers will go through dense and lush rainforests. The beginning of the descent is seen as somewhat of an obstacle-course with climbers constantly having to watch their step for winding tree routes and slippery stones. It will often be necessary for climbers to hold on to branches for support during steep sections. Wild pigs and monkeys are often spotted in the dense forests along with many species of birds.
Climbing Mount Agung Indonesia - Volcanic rock at higher altitudes
When the rainforest thins out, climbers will witness the terrain transition into a desolate landscape of volcanic rocks and ashes. The climb to the summit is over sturdy volcanic rock surfaces and often includes slippery stretches. There are no safety barriers at this section to prevent any falls, so ample body strength or prior training becomes an advantage at this point.
