If you put in above the Lions club, you'll encounter a group of guys that will dive-bomb you! Be careful! (But of course it's all in fun!)

Access points for DIY toobers

Most tubing trips will start at Lion's Club, and end at either the Rio Vista dam or CR 299. Continuing downstream is dangerous and will take 12 hours. The next appropriate tubing is from the CR 266 / CR 101 / Martindale access down to Sculls Crossing. All other access points are for reference only / kayaking.

Rafting trips or kayaking down the rivers can be great fun when there's white water. The rapids that vex tubers are all the more fun for rafts and kayaks. Check with an outfitter.
