KP Hole starts up April 1st on the Rainbow River. I don't know about any of the others. If you have your own tube, you can tube on the river at any time of year. It's just the shuttle services and the tube rentals that don't open all year.
Memorial day- labor day,memerial day is first saturday in april. Hours are 8 a.m -3:30 p.m.
I'm not sure, call or check website. There are several other outfitters doing tubing runs. KP hole is one. I know the rest of the outfitters are up & running. The outfitter at Swampy is running shuttle. Have fun 👍
