Mount Rinjani

Bali’s big bro is the island of Lombok. You can hardly miss it on account of the hulking tops of Mount Rinjani. That’s a 3,726-meter-high volcano that’s actually the second tallest in all of Indo. Those backpacking southeast Asia make the trip across to Lombok specifically to hit up its summit. Be warned: it’s not a walk in the park. For starters, it takes at least two days to complete and there are climbing sections up scree ridges and volcanic chutes. The rewards are stunning views over to the Isle of the Gods, across the Bali Sea, and down to flooded craters far beyond the clouds.
