What if I run out of water on Mt. Rinjani?

Running out of water on Mount Rinjani is a serious situation that our team at Lombok-Indonesia.org actively works to prevent through careful logistics planning, but understanding how to avoid it and what to do if it happens is essential knowledge for every trekker.

Our standard packages include water provision as part of the comprehensive porter services, meaning the team carries and treats sufficient water for cooking, drinking, and general group needs throughout the entire trek. However, individual water consumption needs vary significantly based on body size, fitness level, sweat rate, and the specific weather conditions during your trek. A larger person sweating heavily in tropical heat might need substantially more than a smaller person hiking in cooler conditions.

Your best personal strategy is to carry two to three liters of water in your day pack as a buffer, and to sip regularly throughout the hiking day rather than waiting until you feel thirsty. Don’t rely solely on group water supplies without knowing exactly when the next refill point is scheduled. Communication with your guide about water status is absolutely critical.

If you do find yourself running low despite your best efforts, tell your guide immediately. Do not wait until you’re completely out. Guides can redistribute water from porter supplies, identify safe natural stream sources for emergency treatment, or adjust the hiking pace to reach the next planned water point sooner. Early communication prevents the situation from becoming dangerous.

Prevention is honestly simple: start each day well-hydrated, carry adequate personal supply as backup, sip regularly rather than chugging, and keep your guide informed about your water status throughout the day. The team is there to support you, but they need accurate information about what’s happening with your hydration. Don’t play the hero and hide that you’re running low.
