The journey up Mount Rinjani is more than just a climb—it’s a passage through different worlds. I started in the wide savannahs of Sembalun, pushed myself to the freezing summit at dawn, rested by the mystical waters of Segara Anak Lake, and finally descended through the lush valleys of Torean. Along the way, I learned that Rinjani demands respect, and what you wear can make or break your adventure.
The Sun-Baked Savannah and Chilled Nights at the Crater Rim
The trail from Sembalun is beautiful but brutal. Rolling golden hills stretch endlessly under the open sky, and there’s almost no shade. Within minutes, sweat poured down my face, my shirt plastered to my back. I regretted choosing cotton—it soaked up sweat and never dried.
What worked best here? A moisture-wicking shirt and quick-dry pants. On Sembalun’s trail, breathable fabrics aren’t optional, they’re survival.
After hours of climbing, I reached Plawangan Sembalun (the crater rim camp) at 2,639 meters. The view stopped me in my tracks: the vast crater of Rinjani opening below, and in the middle of it, the shimmering Segara Anak Lake. It looked unreal, like a hidden kingdom.
But as the sun set, the temperature dropped sharply. The wind howled across the rim, and I layered everything I had—fleece, raincoat, extra socks. A proper insulated jacket would’ve been gold here.

Summit Push with Resting at Segara Anak Lake
At 2 AM, we set out for the summit. The trail was steep volcanic sand—two steps forward, one step sliding back. The wind bit through my thin gloves, and my hands went numb. My breath fogged in the air as I pulled my beanie lower and wished for a thicker layer.
By the time I reached the summit at 3,726 meters, I was exhausted, freezing, but also in awe. The sunrise revealed Bali and the Gili Islands in the distance, while Segara Anak glowed far below inside the crater. In that moment, the cold and fatigue felt like a small price to pay.
Descending from the summit, we made our way down to the lake itself. The trail twisted steeply into the crater, and suddenly, we were standing by the turquoise water of Segara Anak.
Here, life felt different. Fishermen cast their lines, steam rose from the nearby hot springs, and hikers soaked their tired legs in the warm water. I sat on a rock, boots off, feet in the steaming pool, staring at the tiny cone of the active volcano—Gunung Baru Jari—rising from the middle of the lake.
That night by the lake, I was grateful for every warm layer I had packed. Temperatures dipped low, but with my fleece and extra socks, I was finally comfortable.
The Descent Through Torean
Leaving Segara Anak, I took the Torean route, and it felt like walking into a lost world. The trail followed river valleys, crossed bamboo bridges, and passed waterfalls that tumbled down sheer cliffs. The air was thick and humid again, and one by one, I stripped off layers until I was back in just a quick-dry shirt.
But Torean was no easy descent. Muddy paths, slippery rocks, and narrow ridges tested my balance. Trekking poles and sturdy boots saved me more than once. By the time I reached the village, I was exhausted—but I’d never felt more alive.


What I Learned About Clothing on Rinjani
- Sembalun is hot: Quick-dry, breathable fabrics are essential.
- The crater rim is cold: Pack a fleece or insulated jacket.
- The summit is freezing: You’ll need thermal base layers, gloves, and a beanie.
- Segara Anak nights are chilly: Extra socks and warm clothes make the lakeside camp much more enjoyable.
- Torean is wet and wild: Trekking poles, waterproof shoes, and balance will get you home safely.
When I finally stepped out of the forest at Torean, my legs were jelly, my face was dirty, but my heart was full. I had crossed savannah, summit, lake, and valley. I had frozen, sweated, slipped, and laughed.
Rinjani taught me this: the mountain doesn’t forgive carelessness, but it rewards those who come prepared. From Sembalun’s scorching hills to the cool magic of Segara Anak, and finally through the wild Torean valley, the journey was not just about reaching the summit—it was about living every layer of the mountain.
