The US White Water Center is a blast.  I have probably been around 5-6 times.  My brother and I did the Rodeo Rafting and it is well worth the $15 extra dollars.  Only Rodeo raft of you have some experience. We swam at least 6 times. But if you can't swim or have never rafted before please don't consider rodeo rafting.   \n\nGet there earlier so you can get a good parking spot.  Also getting there early allows you to get the most out of your day-pass.  A day pass cost between $50-$60 and you can raft as much as you want (usually), zip line, kayak, SUP, and bike. \n\nSpend your entire day there and it will be worth your time.  Also if you just was to go watch people raft (which is a blast) you can watch for free ($5 for parking though)
