Sembalun Lawang ascent

This is the harder but claimed to be a more interesting route to trek Mount Rinjani is the Sembalun Lawang on the east side of the mountain.

Most people will start at Pelawangan Sembalun around 2-3am in order to catch the sunrise at the peak. The starting path is difficult for its steep and slippery and the final ascent is worst where it is narrow. Travelers report that if you do manage to make it to the top, the view is magnificent and well worth it with view of the crater and all the way to the island of Bali while surrounded by giant clouds. The photography here is also amazing!

Up and down both sides

To get the best of both routes and they offer different views of the place, you can always climb up one of the route and down the other. Recommended way is to trek up via Sembalun Lawang, cover the rims and even summit if you like and then down to the caldera before heading back to Senaru.
