Two Gates to the Summit — One Big Decision
Mount Rinjani offers several entry points, but the two most popular starting trailheads are Senaru (northern slope) and Sembalun (eastern slope). Each route has its own character, challenges, and rewards. Understanding the differences will help you plan a trek that matches your fitness level, time constraints, and goals.
Quick Comparison at a Glance

| Best For | Nature lovers, shorter treks | Summit seekers, photographers |
The Senaru Route
Starting from the traditional Sasak village of Senaru on Rinjani's northern flank, this route immerses trekkers in lush tropical rainforest from the very first steps. The path climbs steeply through dense canopy, offering shade and a rich jungle atmosphere.
- Distance: Approximately 9 km to the crater rim (Pelawangan Senaru)
- Elevation gain: Over 2,400 m from trailhead to rim
- Highlights: Waterfalls near Senaru village, incredible biodiversity, traditional village culture
- Downside: Steeper ascent, more physically demanding per kilometre
The Senaru route is particularly popular for 2-day/1-night itineraries focused on reaching Segara Anak crater lake without summiting the peak.
The Sembalun Route
Departing from Sembalun Lawang on the eastern side, this route traverses wide open savannas and rolling hills before the trail steepens near the crater rim. The higher starting altitude means less total elevation gain, and the open landscape provides sweeping panoramic views throughout.
- Distance: Approximately 14 km to the crater rim (Pelawangan Sembalun)
- Elevation gain: Around 1,900 m from trailhead to rim
- Highlights: Open savanna scenery, ideal for the summit push to 3,726 m, star-gazing campsites
- Downside: Longer distance, exposed to sun with little shade
Most trekkers who want to reach the summit of Rinjani use the Sembalun route for ascent, as the final push to the peak is accessed from Pelawangan Sembalun.
The Best of Both: The Traverse Option
The most rewarding itinerary for many trekkers is the Sembalun–Senaru traverse: ascending via Sembalun (ideal for the summit), spending nights at the crater, and descending via Senaru. This 3-day/2-night or 4-day/3-night trek gives you the full Rinjani experience — savanna, summit, crater lake, hot springs, and jungle — all in one journey.
Which Should You Choose?
- Choose Senaru if you prefer jungle trekking, want a shorter route, or are focused on the crater lake rather than the summit.
- Choose Sembalun if reaching the summit is your primary goal, or you prefer open landscapes.
- Do the traverse if you have 3–4 days and want the complete Rinjani experience.
Whichever route you take, Rinjani will challenge and reward you in equal measure.
