You must be ready at 02:00 AM for the Mount Rinjani summit attack. The climb to the summit of Mount Rinjani (3,726 meters above sea level) takes approximately 3–3.5 hours, passing through a steep and sandy trail along the upper slopes of the mountain. Temperatures can drop as low as 4°C, so proper trekking gear is essential, including a warm jacket, long pants, gloves, and a headlamp. Upon reaching the summit, you will be rewarded with an incredible sense of achievement and breathtaking sunrise views stretching across the Wallace Line toward Bali Island, Mount Agung, and Sumbawa Island. Spend around one hour at the summit for photography before descending back to the campsite via the ridgeline, passing through beautiful edelweiss flowers (Bunga Abadi), followed by a well-deserved breakfast at camp.
After breakfast, the trek continues with a descent to Segara Anak Lake, which takes approximately 2–2.5 hours. Along the way, you will enjoy panoramic views of the valley and the majestic Mount Sangkareang on the western side of Mount Rinjani National Park. Upon arrival at the lake, the porter team will prepare lunch while the guide leads you to the nearby natural hot springs. Swimming and soaking in the hot spring water is believed to have healing properties and offers natural relaxation to restore energy and mood. Lunch is served lakeside between 12:00 and 13:00, with stunning views of the active volcano Mount Baru rising from the center of Segara Anak Lake.
At 14:00, after lunch, the journey continues with an ascent to Crater Rim Senaru. The trek to Crater Rim Senaru takes approximately 3–4 hours, traversing rocky cliffs and scenic trails. This section does not require technical climbing skills or special equipment. Throughout the ascent, you will enjoy changing perspectives of Segara Anak Lake from different angles.
You are expected to arrive at the Crater Rim Senaru campsite by 17:00 or before sunset. Enjoy a peaceful sunset with a cup of coffee or tea while the trekking crew prepares dinner. On clear days, this campsite offers spectacular panoramic views of Segara Anak Lake, the Mount Rinjani summit, Bali Island, the Gili Islands, and northern Lombok. While similar in scale to the summit views, the scenery here is seen from the opposite direction, offering a completely different and equally stunning landscape.
