Understanding Mount Agung

Mount Agung, also known as Gunung Agung (Indonesian for ‘Great Mountain‘) or the Mount Agung Volcano, is the highest point and most sacred peak in Bali, standing at 3,142 metres (10,308 feet) above sea level. More than just a hiking destination, it holds deep cultural and spiritual significance, regarded as the dwelling place of the gods by the Balinese people.
As the heart of Balinese Hinduism, Mount Agung plays a central role in rituals and ceremonies. The revered Pura Besakih, known as Bali’s Mother Temple, sits on its slopes and is a key site for religious processions. During sacred festivals, lava surface formations and crater walls near the temple serve as symbolic connections between the earthly and divine.
Beyond its religious importance, Mount Agung is an active volcano with a history of previous eruptions, including the devastating 1963 eruption that reshaped the landscape and affected nearby villages. The eruption began in February 1963 with ash emissions and steam clouds rising from the crater rim. By March, the Mount Agung Volcano’s eruption intensified with lava effusion and pyroclastic flows, causing destruction in nearby villages. The eruption began again in May, triggering explosive activity, widespread lahar deposits, and continued seismic activity.
More recently, scientists have monitored Gunung Agung’s volcanic activity using seismic data, satellite imagery, and reports of ash emissions. These tools track growing thermal anomalies, crater floor changes, and potential geological hazards, ensuring safety for both local residents and climbers.
For hikers, the journey to Gunung Agung’s summit crater is both a physical and spiritual experience. Whether trekking via the Pura Pasar Agung route or the Pura Besakih route, climbers navigate rugged terrain shaped by andesite lava flows and thermal anomalies. The breathtaking view from the absolute summit offers an unparalleled perspective of Bali, Indonesia, with sights of Mount Batur and beyond.
Understanding Gunung Agung’s seismic activity and cultural heritage adds depth to your adventure. Whether you’re scaling the crater rim or witnessing the thin white plume of steam rising from its depths, every step of climbing the Great Mountain is a journey through Bali’s natural and spiritual legacy.
Routes to the Summit of Mount Agung

Mount Agung’s summit can be reached via two primary paths: the Pura Besakih route and the Pura Pasar Agung route. Each trail presents a unique experience and set of challenges, suitable for various fitness levels and adventure preferences.
The Pura Pasar Agung trail is the more popular and manageable route to climb Mount Agung. Starting at 1,700 metres above sea level and ending at the crater rim (2,866 metres above sea level). The ascent takes about 4-5 hours, it offers a shorter, less strenuous climb through lush forests and rocky terrain. With 20-30 hikers per night, it’s a lively route ideal for those seeking a manageable yet rewarding ascent with breathtaking views.
On the other hand, the Pura Besakih trail is a more challenging route, suited for adventurous and physically fit climbers. It begins at Pura Pengubengan (1,200 metres above sea level) and ascends to Mount Agung’s absolute summit (3,142 metres). With steep, muddy terrain, it requires high fitness and endurance, taking 6-8 hours to complete. Less crowded than the Pura Pasar Agung route, it offers a tougher yet more solitary and rewarding climb.
Reaching Gunung Agung’s summit is a true test of endurance, no matter your route. The final push, especially via Pura Besakih, requires navigating steep, rocky terrain with hands-on climbing. Yet, the breathtaking sunrise over Bali, Indonesia makes every step worthwhile.
As you plan your hike, consider your fitness level and hiking experience. Choose a route that matches your fitness level, as both offer unique challenges and rewards. Hiring a guide is highly recommended for safety and a deeper understanding of the mountain’s cultural significance.

Descending Mount Agung

Descending Mount Agung can pose challenges equal to, or even surpassing, those of the ascent. After the exhilaration of reaching the summit and witnessing the sunrise, the journey down can test your endurance and resilience. Fatigue and muscle aches from the climb up can make the descent gruelling, requiring careful navigation of the steep and often slippery terrain.
