Your guide will identify flora and fauna along the way. Lunch is cooked in the jungle. Tonight you sleep in a basic jungle camp — mat, mosquito net, river for washing. Leave your main pack at the guesthouse and carry only a small daypack. Non-swimmers: the river crossing can be walked, just tell your guide.
