Terrific! We set off on the two-day jungle trek with Safrol. We could not have wished for a better guide. He explains a lot and answers every question. Despite our poor English we understood him perfectly. He also speaks a little German and we laughed a lot. My dream came true, we saw many orangutans. Also other monkeys and two toucans. Before we had concerns about the overnight stay. That was absolutely unfounded. It was a great experience. The tubing on the second day was super fun and we felt comfortable and safe at all times. There was a great meal and also in between they always conjured something out of their backpacks. I have celiac disease and I am vegetarian. They took great care of that. But in general I have to give Discover Sumatra a lot of praise. I have written a lot with Christine before. She answered all my questions. Also during our stay she regularly checked if we were doing well and gave us tips for food and other activities.
