My girlfriend and I rented kayaks here for two hours. You are given a quick orientation and the staff makes sure you can do basic navigation, and off you go. We encountered about 6 areas where there was "fast water," or "mini-rapids," and they were a lot of fun. You can go at a very leisurely pace and still get to the pick-up point in plenty of time (two hours.) I brought a camera, but made sure it was in a water proof pouch. Same for my car keys and cell phone. You WILL get splashed, and sometimes water gets in the kayak after you go throughout the "mini-rapids." For a 100+ day, we were very comfortable. Just stick your feet in the water and it will cool you right off. Slather on LOTS of waterproof sunscreen, and bring some in a ziploc because you will probably need to re-apply. We encountered a few "tubers" along the way, but everyone was having fun and behaving themselves. I will definitely be back to do this again.
