Tipping porters on Mount Rinjani is completely optional, and the amount is entirely up to each hiker. Porters come from humble local communities, and they work extremely hard carrying group equipment, setting up camp, cooking, cleaning, and keeping the mountain clean. Any amount, whether small or generous, is appreciated and makes a real difference to them.
Most hikers choose to give a simple cash tip at the end of the trek as a way of saying thank you for the effort and support. There is no fixed rule or required number. Even a modest amount is helpful, and larger groups sometimes pool money together to make tipping easier. The most important thing is the gesture, not the value. Porters are grateful for anything given, and every contribution supports their families and livelihoods.
Tipping is not mandatory, but it is a kind and meaningful way to show appreciation for the people who make the Rinjani trek possible.
