Indulge in a hearty breakfast at the hotel starting at 6 a.m. before embarking on your journey with registration at the Mount Rinjani National Park Office. Your initial destination is post 1 (915 m), a scenic two-hour trek through lush savannas. After that, take a brief 15-minute break at post 1 before pushing forward to post 2 (1,500 m), reaching it within an hour. At post 2, take a longer break and enjoy lunch while being treated to beautiful scenery accompanied by the appearance of rare black monkeys.

Continue your adventure with another hour of trekking to reach post 3 (1,800 m) for a brief rest. From there, traverse several hills toward the majestic Sembalun Crater Rim (2,641 m), a journey of about 3.5 hours. Arriving around 5 p.m., you'll be greeted by awe-inspiring views above the clouds, with Mount Rinjani commanding the horizon, particularly captivating as the sun begins to set. Conclude your first day's expedition with a delectable dinner and a well-deserved rest.
