You get a lot of bang for your buck at this place right here. Only $54 for access to all of the activities and that's a steal!
Whitewater rafting was a blast. Our guide Vinny was awesome! He not only made sure we were safe, but he was also was a ton of fun.
Definitely plan to spend from open until close here if you want to check everything out. Half a day is not enough. Also, rent the $10 locker. It's worth the extra money to be able to access your things an unlimited amount instead of paying $2 every time.
