Mount Agung

Mount Agung is Bali's highest peak at 3,142 metres, in eastern Karangasem Regency. Balinese Hindus regard this active stratovolcano as the home of the gods. The climb is steep and demanding, and most people do it through the night to reach the summit for sunrise. It is far harder than Mount Batur and needs to be taken seriously.

As of April 2026, the PVMBG alert level is 1 (Normal), which means climbing is permitted. The mountain may close during major Hindu ceremonies, especially the Ida Bhatara Turun Kabeh (IBTK) ceremony at Besakih, usually in April and May. Since January 2025, foreign climbers must use a licensed guide; unguided attempts are illegal and can result in deportation.

Climbing routes

Two main routes lead up the mountain, each starting from a different temple. The choice depends on your fitness level and whether you aim for the true summit.

The Besakih route is longer and steeper, starting from the Mother Temple on the southern slope and reaching the true summit with a full 360-degree panorama. The Pasar Agung route is shorter and more common, reaching the south crater rim with similar views but ending 111 metres below the true summit. Most operators run Pasar Agung unless you specifically request Besakih.

Climbing costs (2026)

Mount Agung does not charge a national park permit fee. Costs cover the mandatory licensed guide, transport, and small temple donations. Most packages include hotel pickup, pre-dawn refreshments, a simple summit breakfast, headlamp and trekking pole rental, and temple entry donations.

What to expect on the hike

1. Pickup from your hotel between 10:30 PM and 11:30 PM, depending on where you are staying.
2. Arrive at the trailhead around 1:00 AM to meet your guide and complete registration.
3. Start hiking by 1:30 AM. The trail is steep volcanic scree with loose rock and sections that feel very steep.
4. Expect summit temperatures between 0 and 10 degrees Celsius, with strong wind chill. Layers are essential.
5. Reach the summit viewpoint around 5:30 AM to 6:00 AM for a sunrise near 6:00 AM.
6. Descend after sunrise, arriving back at the trailhead around late morning.
7. Return to your hotel by early afternoon.

What to bring

• Two to three warm layers for the summit, including thermal, fleece, and windproof outerwear.
• Headlamp with fresh batteries, unless you plan to use the rental option.
• At least two litres of water per person.
• Rain jacket or poncho, because weather can change quickly on the mountain.
• High-energy snacks for the climb.
• A small donation for temple entry (IDR 20,000 to 50,000).
• Sturdy hiking shoes with good grip for loose volcanic scree.

Best time to climb

The dry season from April to October offers the best conditions: the trail is firmer, visibility is clearer, and rain is less likely. The wet season from November to March brings rain, slippery slopes, and occasional closures due to unsafe conditions. July and August are the busiest months, while May, June, and September offer a good balance of weather and smaller crowds.

How to get there

Tour packages generally include hotel pickup and drop-off anywhere in Bali. The drive from South Bali to the trailhead takes about 2 to 2.5 hours. If you arrange transport independently, Mount Agung is in Karangasem, roughly 2 hours from Ubud and 3 hours from the airport. Most climbers book through an operator because the mandatory guide requirement makes self-arranged climbs impractical.
