From here It is another good hour walking up to the peak of the Rinjani volcano on Lombok, Indonesia. These hikers didn't make it to the top in time for the sunrise. Neither did I. But at a respectable height of almost 3.700m, I think I got a cool sunrise from quite where I was.
The Rinjani volcano is a touristic highlight on the Indonesian island of Lombok. At least 200 people in many small guided groups were climbing to the top when we were there. Only a small percentage make it to the top in time for sunrise. You leave basecamp at 2.600m at 2.30am to go to the summit at 3.726m. Sunrise is at about 6 am. It is a very strenuous and frustrating climb because of the steepness of the last 1.100m and the amount of loose gravel on the path.
But the views are breathtaking. Check out the photo below looking the other direction and notice the massive shadow the volcano makes on the clouds behind it....
In the distance on this second photo you can clearly see Bali and, if you look closer, the three small Gili islands.
