From 45min.to an hour. Most of the river was closed the officials claim that it is A 10mile long.I could not explore it all.
Yes you can rent picnic pavilion they have two big ones. Is take like 20 to 30 minutes down the river is amazing. You have to be in the park around 7 in the morning that way you can enter to the park.
Either bring your own tube or rent one at the bar BEFORE you get to the actual park. It's just before you get there, you can't miss it. The float down takes anywhere from 10 minutes and up. No longer than 30. Just depends on how you enjoy it. Just be sure to actually start at the head of the spring. Too many people don't find it their first time here and miss the beauty!
They do have picnic tables. The river is not that long. About 5 mins and you've done the whole river but it is worth it. We saw otters and lots of different fish.
