The white water center is a pretty epic place for outdoor activities. Trail running, biking, rock climbing, ropes courses, zip lining, oh and white water rafting of course. They have food and drinks/beer on site so you really don't have to leave! Oh, and most importantly, it's dog friendly.
I would highly recommend going on a weekday if possible just because the lines get super long on weekends. It's a little expensive, but worth the money. A lot is included in the different passes you can purchase. If you buy just a land pass, you can do almost everything except white water rafting and the canopy tour. You will definitely leave tired and happy you went!
There's also things you can do for free (aside from the $5 parking fee). You can do the trails, bike around the place, paddle board if you bring your own paddle board, yoga, and river jam for some music and relaxing on the lawn. Awesome place, check it out!
