We initially didn't want to use a tour guide, so we just wanted to go on our own. Then, as soon as we arrived, we took some photos, and the gentlemen on duty helped us take them, and the results were amazing. The tour guide charged us 100,000 Rupiah, so we asked for a fair price from the start. He explained the route in detail, and took the best photos for us as souvenirs. If it weren't for the gentleman, we would have ended up in a local's house.
