Routes to the Summit

1. Senaru Route

The Senaru route is the most popular and accessible path, offering a mix of scenic beauty and cultural experiences.

• Day 1: The trek begins in the village of Senaru at an altitude of 600 meters. The first day’s hike takes you through lush tropical rainforests, where you can spot various flora and fauna. The day’s trek ends at Senaru Crater Rim (2,641 meters), providing a stunning view of Segara Anak Lake and the surrounding caldera.
• Day 2: From the crater rim, the trail descends into the caldera to Segara Anak Lake, where you can relax in the hot springs and enjoy the serene environment. The campsite for the night is usually near the lake.
• Day 3: The final push to the summit begins early in the morning. This steep and strenuous climb is rewarded with a breathtaking sunrise view from the summit. After enjoying the summit, you’ll descend back to the lake and then return to Senaru.

2. Sembalun Route

The Sembalun route is considered the easiest and offers spectacular open views of the savannah.

• Day 1: Starting from Sembalun village (1,150 meters), the trail winds through grasslands before reaching the Sembalun Crater Rim (2,639 meters), offering panoramic views of the volcano and beyond.
• Day 2: A pre-dawn start is necessary to reach the summit by sunrise. The climb is challenging but the sunrise view from the top is worth the effort. After descending from the summit, trekkers usually head to Segara Anak Lake for a well-deserved rest.
• Day 3: The final day involves a hike back to Sembalun village, completing the trek.
