Introduction to canoeing: Canoeing on the Rapti River or Narayani River is a more leisurely way to visit the park. You may see waterfowl and crocodiles. If you are lucky, you might even see the very rare Ganges river dolphin. A canoe trip starting from Sauraha costs 850 rupees per person and involves an hour's journey on the river, followed by a two-hour guided walk back to Sauraha, stopping at an elephant breeding center along the way.
