Walking in white water is along the plank road beside Niagara Falls to enjoy the waterfalls and whirlpools produced when the flood-like River falls. This road is very exciting to walk. First, take the elevator down 70 meters, then walk along the 70-meter-long underground passage to the 300-meter-long wooden road. Along the road, there are two scenic areas near the Niagara River. Remember that it's a $10 ticket.
