I was away a little over a month ago to one of the many Indonesia’s national parks. The one I went to was called Gunung Leuser and located somewhere in North Sumatera.
The park was interesting. To enter the park, I had to actually cross a small river with somewhat fast current. The area around the park was quite secluded. It was hard to find reception for cellphones and the attempt for using a wifi failed quite horribly.
