Looks like a nice place to travel to, considering it is such a small country! Although I would prefer paddling a boat myself on the Brunei River instead of relying on a tour guide. But since crocodiles seem to be common there it would be too dangerous to allow it?
Yes, I think it's dangerous to tour the boat alone without a tour guide since many crocodiles really roam around the place. Plus the tour guides know where to find the monkeys' hideouts 😉
