This meandering creek around the park is designed so you can spend about 30 minutes floating around or use it as relaxing transportation and get off along the way. A fantastic place to get a tan, too. Two downsides: 1) gets so crowded in the middle of the day that you're wedged in between inner-tubes, mostly among strangers, and 2) the ice cave part has jets of freezing cold water that you can't see before they fire. Luckily, there is a detour around the cave.
