I went for a three day two night trekking with Rinjani Trekking Center. We had an amazing guide (Anci) and great porters who carried our stuff. The trekking was well organized, we could borrow jackets and head lights for free and the food was amazing (and we got A LOT)! Thanks to our nice guide Anci we had an amazing experience on the vulcano and everyone made it to the top of the summit. Would recommend this trip to everyone who loves adventure!
