Sembalun vs Senaru: which Rinjani trailhead is right for you.
The trailhead decides your terrain, open savannah or shaded rainforest, and whether you're heading for the summit or the rim. Here's the honest difference between the two, and how each pairs with a route.
The three trailheads, in one breath
Most people only ever weigh up two, but there are three gateways, and knowing what each one is clears up most of the confusion.
Sembalun is the dry savannah gateway on the east side: open, exposed, and the start for every summit route because its long grassy grade helps you acclimatise. Senaru is the rainforest gateway on the north, green, shaded, wetter, home to the no-summit crater-rim route and the classic forest way down. Torean isn't a start at all: it's a spectacular green-canyon descent of rivers and waterfalls, a way off the mountain rather than onto it.
Each gateway, and what it's like underfoot
This page stays on the ground: terrain and feel. For who reaches the summit and how many days each takes, the route matrix has it.
SembalunThe savannah summit start
Open grassland under a big sky, dry and exposed to the sun. Every summit route starts here because the long, gentle savannah grade walks you up gradually, better for acclimatising than a steep start would be.
Less shade, more heat in the day, and the wind has nothing to stop it. The trade is that gentler gradient onto the mountain.
You start here if you're going for the summit.
SenaruThe rainforest rim start
Cool, green, shaded rainforest, wetter underfoot and alive with birdsong. This is the gateway for the no-summit crater-rim route, and the classic forest path people descend on after the summit.
Steeper and more enclosed than Sembalun, with roots and mud after rain, but you're out of the sun and into the trees.
You start here if you want the rim and the forest, not the summit night.
ToreanThe green-canyon descent
Not a start, a descent. A lush canyon of rivers, waterfalls and footbridges, threading down through some of the greenest country on the mountain. Longer routes use it to come off a different way than they went up.
Steep and long on tired legs, but easily the most scenic exit, and a completely different landscape from where you began.
You finish here if you want the views to keep coming on the way down.
The cleanest treks often start in one place and finish in another: up the Sembalun savannah, down through Senaru's forest or the Torean canyon, so you never retrace your steps.
Which trailhead pairs with which route
A quick map of route to start to descent. The full comparison (days, summit or not, who each suits) lives on the routes page.
Notice the pattern: summit routes all start at Sembalun and differ mainly in how they come down. The rim route is the one that starts, and stays, on the Senaru side.
Getting to each trailhead
From Bali, the Gili Islands, or Lombok airport, here's the shape of it. We arrange pickup anywhere on Lombok; the cross-water routings have a few moving parts we'll confirm for your trip.
Tell Pak Wil where you're coming from and he'll sort the pickup and tell you when to travel.
Tell Pak Wil how many days you have and how you walk, and he'll tell you which trailhead, and which way down, suits your trip.
He answers his own WhatsApp, 07:00-21:00 WITA. A recommendation from someone who walks both sides, not a sales pitch.
WhatsApp Pak WilPick by what you actually want to see
Forget the names for a second. Decide by the landscape you want to walk through, and the trailhead follows.
Want the summit and the sunrise?
You'll start at Sembalun, there's no other way up. The savannah grade and a rim night first are part of why it works. Then choose your way down: the Senaru forest or the Torean canyon.
Want the view without the 2 a.m. scree?
Start and stay on the Senaru side with the crater-rim route: the caldera, the lake far below, the camp above the clouds, and a forest you'll actually enjoy.
Want the most scenery on the way down?
Choose a route that descends through Torean: the rivers, waterfalls and footbridges make it the most beautiful exit, and a complete change from the open ground you climbed.
Still torn between Sembalun and Senaru? It almost always comes down to one question: are you set on the summit, or is the rim enough? Summit means Sembalun; rim means Senaru. Everything else is detail Pak Wil can sort with you.

"People agonise over Sembalun or Senaru like it's the whole trip. It isn't. It's just whether you want the summit or the rim. Tell me that, and I'll tell you where you start."
