Mount Rinjani had a clear trash situation and overcrowding problem. Google any picture of epic treks to Rinjani and you’re seen pictures of people claiming they came and conquered Mt. Rinjani, the second-highest volcano in Indonesia.
At one time, 89,000 visitors crammed Mt. Rinjani in a year making it a swampy mess of a terrible trash situation. Think about it: trash accumulated on hiking paths and campsites, trees that are being cut down to make hiking sticks and campfires that run the risk of turning the mountain into ashes are leaving a heavy footprint from the hiking activities.
