The climb to 3,726 metres is the crux of the whole trek — a 2 AM start, a slope of loose scree, and a sunrise you'll never forget. Here's exactly what to expect, and how to give yourself the best shot at the top.
If Rinjani has a defining moment, this is it. The summit push happens on the final morning of your trek, from the crater rim camp at Pelawangan (Sembalun side). It's the hardest few hours of the trip and, for almost everyone, the most memorable. Knowing what's coming makes a real difference — both to your odds of reaching the top and to how much you enjoy it.
The goal is to stand on the summit as the sun comes up. From the top you look east over Sumbawa, west across the whole of Lombok, and down onto a sea of cloud with the crater lake glinting below. Cloud tends to build later in the morning, so an early arrival gives you the clearest views — and time to get back down before the sun softens the scree.
| Time | Stage | What it's like |
|---|---|---|
| ~1:30 AM | Wake & tea | A hot drink and a light snack at camp. Layer up — it's cold and dark. |
| ~2:00 AM | Set off | Head-torches on, single file along the ridge. Steady, slow pace. |
| 2–4 AM | The ridge | A long, rising traverse. Firm underfoot at first, then increasingly sandy. |
| 4–5:30 AM | The scree | The crux: steep loose volcanic sand where you slide back with each step. Patience wins here. |
| ~5:30–6 AM | Summit | 3,726 m. Sunrise over Lombok, Sumbawa and the crater lake below. |
| 6–9 AM | Descent | Faster on the way down — you can almost ski the scree — back to camp for breakfast. |
The final section is the part everyone remembers. It's a slope of loose volcanic sand and gravel, steep enough that for every two steps up you slide one back. It's not technical — there's no climbing, no exposure that needs a rope — but it is relentless, and it's where most people are tempted to turn around.
The trick is rhythm, not power. Short steps, a steady breath, trekking poles for balance, and small rests standing rather than sitting. Kick the edge of your boot into the slope to find firmer ground. Your guide will pick the best line and set a pace you can sustain. Getting to the top is far more about patience than raw fitness.
Turning back is not failure. The summit push is optional, altitude affects people unpredictably, and some mornings the weather simply doesn't cooperate. Plenty of trekkers stop short of the top and still describe the crater-rim sunrise and the wider trek as the best days of their trip. Your guide will support whatever you decide — your safety always comes first.
