Regular rowing results in a stronger back and an increased ability to mimic the three-part harmony of the river's song. Practice natural arias with today's Groupon for a rafting trip from Performance Tours. Choose from the following options:

• For $30, you get a half-day, Class III–IV (moderate) trip to Bighorn Canyon (up to a $63.10 total value, including a $5.10 park-usage fee and a $7 wetsuit rental), departing from the Royal Gorge location in Canon City.
• For $30, you get a half-day, Class III–IV (moderate) trip to Browns Canyon (up to a $63.10 value, including a $5.10 park-usage fee and a $7 wetsuit rental), departing from the Buena Vista location.

Performance Tours escorts adventuresome raft-rowers on thrilling rides through the scenic vistas of Colorado waterways. A Class-III+ trip through Bighorn Canyon offers a moderate ride, appropriate for rafters 7 years of age and older. After pushing off, oar pullers navigate through a stretch of the foamy Arkansas River, which includes three rocks, five points, and the sassy section known as Spike Buck, while scanning the canyon for a rare peek at Bighorn-sheep choir practice. Browns Canyon plays host to a Class-III+ ride on the Arkansas River, offering paddle pushers thrilling oar-obstacles, with names such as Pinball and Zoomflume, which conspire with the scenic mountains and deserts to take rafters' breaths away.

Rafters should arrive ready to row 30 minutes before tour time at the corresponding Performance Tours office, each of which offers ample space for resting land vehicles. Shuttles transport paddlers from the office to the departure point and back. Performance Tours supplies all rafting equipment, including a wetsuit, booties, and a dry bag to protect release forms for photographed wildlife. Rowers should wear clothing that dries quickly and bring a change of clothes. All Performance Tours offices offer changing rooms for soaked souls and superhero alter egos.
