$75 for a Waterfall-Rappelling Experience for One (a $150 Value)

Certified outdoorsmen lead adventurers in challenging but safe waterfall-rappelling trips at locations within about 15 minutes from St. Catharines and Niagara Falls, which vary depending on the time of year and current water levels. After a practice jaunt down a dry slope into the gorge, guests hit the water clad in provided safety gear and harnesses. The trip lasts three to four hours and can be undertaken by guests 12 and older and less than 270 pounds, with an accompanying adult required for guests under age 16.
