Mount Agung Volcano

Mount Agung is the dominant volcanic peak on the island of Bali and is the island’s highest point and principal sacred mountain for Balinese Hinduism. It is an active stratovolcano that shapes eastern Bali’s landscape and cultural geography.

The slopes are home to important temples, most notably the large Pura Besakih complex which is considered Bali’s mother temple and sits on lower flanks of the volcano. Treks to the summit are popular with experienced hikers and require guides, as routes are steep and conditions can change with volcanic activity.

The volcano has a history of significant eruptions in the 20th and 21st centuries which have caused local evacuations and ashfall; monitoring and temporary closures occur when activity increases. Mount Agung is situated in eastern Bali, rising above surrounding towns and rice terraces and visible from much of the island.

• Highest peak and sacred site: The mountain is considered the highest point on Bali and is a sacred site for Balinese Hindus, with the major temple complex Pura Besakih located on its lower slopes.
• Climbing conditions: Climbs to the summit are steep and often undertaken at night by guided groups; access can be restricted during periods of volcanic activity.

Gunung Agung is an extremely sacred site, and permission is required before climbing; this can be obtained from one of the temples at Besakih. Climbers should dress respectfully and carry a small gift to leave on the mountain for the local gods.

Reaching the summit in time for sunrise means climbing overnight, setting off at around 22:00. This also avoids the heat of the day, and the scenery can still be enjoyed on the cooler descent in the early morning.

The best way to make the ascent is with a guide hired from the temple complex at Besakih. A reasonable level of fitness is needed to reach the summit, but a guide will point out the easiest route and share some of the area’s history.

Most trips to Mount Agung start from eastern Bali towns such as Amed or from the southern tourist hubs (Ubud, Candi Dasa). The nearest airport is Ngurah Rai (Denpasar); organized treks include transport to trailheads (e.g., Pura Besakih area). Summittreks typically begin very early (pre-dawn) to reach the top for sunrise.

• Respect the sacred shrines-Besakih and other temples on Agung's slopes are active; dress modestly if visiting temple sites.
• Check local advisories-Agung is an active volcano; eruptions in 2017-2019 disrupted flights and required evacuations.
• Hire an experienced local guide for summit attempts; the climb is steep, scramble-heavy, and can be dangerous in bad weather.
