Mount Agung, standing at 3,031 meters (9,944 feet) above sea level, is Bali’s tallest and most sacred volcano. Known for its challenging climbs, breathtaking sunrises, and spiritual significance, Mount Agung attracts adventurous hikers and pilgrims alike. Before attempting this hike, it is crucial to understand the Mount Agung hike difficulty, required preparation, and what to expect on the journey to the summit.
This guide provides an in-depth overview of the hike, including trail conditions, fitness requirements, safety tips, and insights into how to successfully conquer Bali’s highest peak.
1. Overview of Mount Agung
Mount Agung is located in eastern Bali and dominates the island’s skyline. Its imposing height and active volcanic status make it a formidable challenge for hikers. The volcano holds spiritual significance, housing Pura Besakih, Bali’s largest temple complex, at its base. Hikers not only encounter physical challenges but also enjoy spectacular views of Bali, including Mount Batur, the coastline, and the surrounding rice terraces.
Because Mount Agung is sacred and active, hikers should always check local advisories and obtain the necessary permits before attempting the climb.
2. Understanding the Difficulty of the Hike
The difficulty of Mount Agung can be described as strenuous to very strenuous, depending on the route, weather conditions, and the hiker’s fitness level. Here are the main factors contributing to its difficulty:
✔ Elevation and Altitude
At over 3,000 meters, altitude can cause fatigue, shortness of breath, and in some cases, mild altitude sickness. Hikers should pace themselves and stay hydrated.
✔ Steep and Rocky Trails
The climb features steep inclines, loose volcanic rocks, and uneven terrain. Sections of the trail require careful footing and sometimes scrambling with hands.
✔ Long Duration
Most summit hikes take between 6–10 hours round-trip, depending on the route and pace. Early morning starts (around 2:00–3:00 AM) are typical for sunrise treks.
✔ Weather Conditions
The mountain is prone to sudden weather changes. Rain can make trails slippery, while early morning temperatures can drop below 10°C (50°F).
✔ Physical Fitness Required
Hikers should have a moderate to high level of fitness, including endurance, balance, and leg strength. Prior hiking experience is highly recommended.
3. Popular Routes and Their Difficulty Levels
Mount Agung offers two main routes for climbers: Pura Besakih Route and Pura Pasar Agung Route.
1. Pura Besakih Route
- Starting Point: Besakih Temple
- Distance: Approximately 14 km round-trip

2. Pura Pasar Agung Route

Both routes require early morning starts for sunrise summits, making night hiking with a headlamp necessary.
4. Physical Preparation for the Hike
Given the strenuous nature of the Mount Agung hike, proper preparation is essential:
✔ Cardiovascular Fitness
Activities like running, cycling, or stair climbing can improve endurance for the long ascent.
✔ Strength Training
Leg muscles, core stability, and ankle strength are crucial for managing steep inclines and rocky terrain.
✔ Acclimatization
If possible, spend a day or two at higher altitudes, such as near Mount Batur, to help your body adjust.
✔ Flexibility
Stretching before and after hikes reduces the risk of injury and helps with scrambling sections.
