Mount Rinjani, standing majestically at 3,726 meters, is the second-highest volcano in Indonesia and offers one of the most challenging yet rewarding trekking experiences in Southeast Asia. The trek from Sembalun to Senaru is the classic route, taking hikers through diverse landscapes, from savanna to dense forest, culminating in breathtaking views of the crater lake and the surrounding area. Here is a detailed account of this incredible journey.

The path gradually inclines, and after a few hours, the terrain becomes steeper and more rugged.
The first significant stop is at the Sembalun Crater Rim. Here, the panoramic views are nothing short of spectacular. As the sun sets, the sky transforms into a canvas of vibrant colors, painting the rugged landscape in hues of orange and pink. The night is spent camping at the crater rim, where the temperatures can drop significantly, so warm clothing is essential.

After taking in the breathtaking views and capturing the moment with photos, the descent back to the crater rim begins. This is followed by a hike down to Segara Anak Lake, nestled within the crater.
