Detailed Day-by-Day Itinerary: Mount Rinjani 3D2N Sembalun-Senaru Traverse
Day 1: Sembalun Village to Sembalun Crater Rim (Plawangan Sembalun)
- Starting Altitude: 1,100 meters
- Ending Altitude: 2,639 meters
- Trek Duration: 6 – 7 hours
- Highlights: Open savanna scenery, view of the summit, spectacular sunset over Lombok.
Your journey begins early morning in Sembalun Village after registration at the Mount Rinjani National Park office (RIC). The first half of the trek takes you across wide, open grasslands with gentle inclines passing Pos 1 (Pemantauan), Pos 2 (Tengengean), and Pos 3 (Pada Balong).
After Pos 3, the challenging climb begins up the infamous Bukit Penyesalan (Regret Hill). The steep, winding trail leads directly to Sembalun Crater Rim (2,639 m). Here, your team sets up campsite overlooking the spectacular Segara Anak crater lake, Mount Baru Jari (the active inner cone), and the majestic Rinjani summit towering above.
Day 2: Rinjani Summit Attack, Segara Anak Lake, Hot Springs & Senaru Crater Rim
- Summit Altitude: 3,726 meters
- Campsite Altitude: 2,641 meters (Senaru Crater Rim)
- Trek Duration: 9 – 10 hours total
- Highlights: 3,726m summit sunrise, volcanic hot springs, Segara Anak Lake, Senaru Crater Rim.
1. The Summit Push (02:30 AM Start)
Wake up before dawn for a hot drink and light breakfast. The summit trek takes approximately 3 to 3.5 hours over loose scree, gravel, and volcanic sand. Reaching the Mount Rinjani Summit (3,726 m) at sunrise rewards you with 360-degree views stretching across Lombok, Mount Agung in Bali, and Mount Tambora in Sumbawa.
2. Descent to Segara Anak Lake & Hot Springs
After descending back to Sembalun Crater Rim for a hearty breakfast, continue the descent into the caldera toward Segara Anak Lake (2,000 m). Rest near the turquoise lake water and soothe tired muscles in the natural volcanic hot springs, renowned for their therapeutic mineral properties.
3. Climb to Senaru Crater Rim (Plawangan Senaru)
In the afternoon, trek up the opposite side of the crater wall to Senaru Crater Rim (2,641 m). This campsite offers a totally different perspective of Mount Rinjani, featuring incredible views of the lake, crater rim sunset, and Mount Agung on the horizon.
Day 3: Senaru Crater Rim to Senaru Village (Descent Through Rainforest)
- Starting Altitude: 2,641 meters
- Ending Altitude: 600 meters
- Trek Duration: 5 – 6 hours
- Highlights: Tropical rainforest canopy, wildlife spotting (Ebony leaf monkeys), lush flora.
On the final morning, enjoy a relaxing breakfast while watching the sun rise over the lake. The descent from Senaru Crater Rim down to Senaru Village passes through dense tropical rainforest.
Unlike the exposed sunny trails of Sembalun, this shade-covered descent protects you from the harsh sun. Keep an eye out for rare black ebony leaf monkeys (Trachypithecus auratus) and exotic birds along the trail. Arrive at Senaru Village by afternoon for transfer to your next destination in Lombok (Senggigi, Kuta Lombok, or Bangsal Harbor for the Gili Islands).
Why Choose Sembalun Entry over Senaru Entry?
Many hikers wonder whether to trek from Sembalun to Senaru or Senaru to Sembalun. Here is why starting in Sembalun is superior:
- Higher Starting Point: Starting at 1,100m in Sembalun saves you 500 vertical meters of climbing compared to starting at 600m in Senaru.
- Fresh Energy for Summit Day: By starting in Sembalun, you tackle the summit push on Day 2 morning when your legs are freshest, rather than attempting it tired on Day 3 after climbing out of the lake crater.
- Gentler Final Descent: Ending in Senaru allows you to hike down under dense forest canopy, which protects your skin and body from intense afternoon sun and heat.
