Hikers do not need to carry large amounts of water on Mount Rinjani because the porters provide all the drinking water needed throughout the trek. At the start of the climb, each hiker usually carries one bottle or hydration bladder for easy access, and the porters refill the supply at every meal stop. This system keeps your backpack light while ensuring you always have enough water for the long climb and the summit push.
The summit day begins very early, so carrying at least one and a half to two liters during the ascent is helpful. However, you do not need to bring extra bottles or heavy water containers because the porters manage the overall supply. They carry the main stock of water, distribute it as needed, and make sure each hiker stays properly hydrated during the trek.
Since the porters handle all water logistics, hikers only need to bring a reusable bottle or hydration bladder and drink regularly throughout the climb. This makes the trek easier, safer, and more comfortable.
