Our Yellowstone whitewater rafting trip is a fun, wide, high-volume river that features rolling wave rapids. Rapids vary in size depending on water levels. Families love it! The Yellowstone white water rafting trip is great for children ages 6 and up. Spectacular views may include spotting wildlife such as river otters and bald eagles. The Yellowstone River office is located in Gardiner at the North Entrance to Yellowstone National park, just minutes from Mammoth Hot Springs. We are located on Main Street (Scott Street) on a riverfront property within walking distance from lodging and campsites in central Gardiner. You can even see some of the rapids from our backyard!
