Mountains in Indonesia - Asia

Indonesia is a delight for peakbaggers (or gunungbaggers). There is nowhere better to climb volcanoes, offering the full spectrum from dormant to furiously active, from quaint day-hikes to week-long treks up epic mountains.

Mount Lawu

3,265 m (10,712 ft)

Mount Lawu is a fun, amateur friendly, overnight climb, and a portal to other dimensions

Mount Lawu, sitting on the border of East and Central Java in Indonesia, is a fun and easy 2-day hike. Both geologically and spiritually, there are some strange happenings afoot on Lawu: Ancient pyramids, cracks opening in the earth’s surface, the smell of sulphur, and reports of paranormal disappearances.

Mount Merbabu

3,145m (10,318 ft)
Situated in Java, Indonesia, Mount Merbabu is popularly known amongst the hiking community as Merapi’s lesser known sibling. However, in recent years many hikers have been known to choose Merbabu over Merapi, specially due to Merapi’s active volcanic status.

Mount Arjuno

3,339m (10,955ft)

Arjuno-Welirang: The Half-Active, Half-Dormant Volcano

Situated in East Java, Indonesia, Mount Arjuno-Welirang is a twin peak volcano. Whilst Arjuno is dormant, Welirang is still considered active even though the last eruption took place back in 1952. The Arjuno-Welirang hike has many trails and can last from 2-3 days.

Mount Gede-Pangrango

3,019m (9,904ft)

Mount Gede-Pangrango: Two Climbs in One Just Outside Jakarta

Not too far off from the busy city of Jakarta sits one of Indonesia’s easier hikes: Mount Gede-Pangrango. The volcano has 2 separate peaks making this hike a fun 2 day weekend getaway for amateurs and advanced climbers alike.

Mount Raung

3,332 m (10,932 ft)

Making It Back Alive From Mount Raung!

Famous amongst volcano trekkers, Mount Raung is located in East Java, Indonesia. Smoke still actively circulates the crater rim of this angry giant, years after its last eruption in April-August 2015.

Mount Sinabung

2,460m (8,070ft)

Sinabung is currently (as of July 2019) too dangerous to climb because of ongoing volcanic activity.

In August 2010, after 400 years of being dormant, Sinabung surprised us all by erupting, and it has been regularly erupting ever since. What was a fun day-hike from Brastagi with lush green vegetation all the way up is now anybody’s guess.

Mount Agung

3,031m (9,944ft)

Mount Agung is the home of Balinese gods.

Any one of Mount Agung’s 3 regular climbs can be a challenging and spiritually uplifting distraction from Bali’s more laid back (and often less wholesome) attractions. When it is not erupting, it can be climbed in around 10 hours through some of Bali’s most beautiful mountain slopes.


790m (2,600ft)

A hissing, lava-spitting, primordial island of earthly anger that you should definitely climb, but only if you’re allowed to!

Imagine a volcano just exploding into nothing. Krakatau did in 1883, and has since been the most dynamically changing island on the earth. Climbing it depends on the say-so of volcanologists, but the snorkeling is great too.

Mount Merapi

2,930m (9,610ft)

Merapi, or “Fire Maker”, is one of Indonesia’s most active volcanoes, yet is strangely one of the most popular hikes.

The 4km long hike contains a portion where 700m is climbed at about 45 degrees. If you’re fit, you could expect to reach the summit in under 4 hours. You don’t want to be up there too long though, as it erupts every 5 to 10 years, and the last eruption killed 350 people.

Puncak Jaya

4,884 m (16,024 ft)

Puncak Jaya (Carstensz Pyramid) is Southeast Asia’s Mount Everest

Carstenz Pyramid (Puncak Jaya) is one of the “7 Summits” – the highest points on each continent – it being assigned to Australasia rather than Asia. It is the highest mountain between the Himalayas and the Andes.

First conquered in 1962 by an expedition led by Henrich Harrer (who famously spent 7 years in Tibet and climbed the North Face of Elger). He was joined by a geologist Jean Jaques Dozy who spotted an oddly dark and green-tinged peak that turned out to be the richest gold and copper deposit ever found.

Mount Semeru

3,676m (12,060ft)

Mount Semeru is an angry volcano. It has been erupting since 1967, yet is a favourite trekking destination in Indonesia!

Should you summit it, you will almost certainly see an explosion or two – they typically occur in 10 to 30 minute intervals – but at least they’re small and regular…for now!

Mount Rinjani

3,726m (12,224ft)

In 1257, on the Island of Lombok, Mount Rinjani exploded leaving a hole the size of Manhattan.

The explosion covered neighbouring Bali with rocks and ash, and eventually covered the world with sulphur. Today, Rinjani is still highly active, yet around 100,000 climb it every year owing to its verdant jungle trails, azure crater lake, and ongoing volcanic rumblings.

Mount Kerinci

3,805 m (12,483.6 ft)

Mount Kerinci is the tallest of Indonesia’s many volcanos, and one of the most breathtaking.

Being an 8 hour drive from the nearest major airport on Sumatra, Kerinci is one of the most secluded jungle treks and mountain climbs in Southeast Asia. It would normally take two days and a night to summit Kerinci, and you may not spot another soul.

Mount Bromo

2,329m (7,641ft)

Mount Bromo: How To Make The Most Of An Indonesian Sunrise

Mount Bromo is a volcano famed for its stunning and immense caldera. Climbing to it’s edge in time for sunrise is a treat the likes of which even the most amateur of photographers can capture – a symphony of lights and shadow, mists and smokes, greens and browns.

Mount Bintan

336m (1,102ft)

Mount Bintang is a perfect day hike to enrich a weekend getaway from Singapore.

With its attainable height and relatively uncomplicated terrain, Mount Bintang is an attractive diversion for amateur hikers and beach holidaymakers. It’s easily reachable from Singapore, and is brimming with natural flora and fauna in it’s heavily jungled landscape.

Ijen Crater

2,350m (7,710 ft) (at the crater rim)

This 2-hour climb to a sulphurous crater lake will leave you breathless and mystified

Situated in Eastern Java in Indonesia, Ijen Crater is an active volcanic crater that has become a sulphur mine. Yet it is a scenic hike, and is famous for oozing out blue flames that are visible at night.
