Rinjani Senaru Rim in Two Days: Plant a Tree on the Mountain, Children from 7

Green Rinjani runs this two-day walk to the Senaru crater rim, and adds something none of the other Rinjani packages do: you plant a tree on the mountain while you are up there. The operator frames it as its environmental contribution, and it happens on the trek rather than being a donation added at checkout. The walking is seven hours on the first day and six on the second. Those are the numbers to plan around. The route starts and ends at Senaru village, inside Gunung Rinjani National Park, and climbs to the crater rim above Lake Segara Anak, which sits in the volcano's crater below the camp. This is the gentle way up Rinjani. The operator recommends it to first-time trekkers and to families, and sets the minimum age at seven years old, which is a firmer statement than most listings here make about children. Departures run every day, weather permitting. Cancelling at least 24 hours before departure gives a full refund.
