That's one of the best things ever done. The instructors are great and experienced, deal well with people who are scared. Visit the park and you will have the best memories from your trip!
Gorgeous drive in the fall. It can be crowded at some spots, but people seem to be aware and don’t dawdle too long. I highly recommend the drive, especially late October when the leaves are changing and it’s (hopefully) been raining so the waterfalls are really pumping!
