I went here with my sister and our kids for a couple hours of tubing in January. The staff were great at making sure we were getting the right passes and super friendly. We weren't sure whether or not we required helmets but we brought our own just incase and when the one we had for my nephew didn't work out, they held it at the desk for me instead of me having to run it back to our vehicle which was awesome! It seems you don't have to have one, but I figure better to be safe than sorry, that being said, I didn't see anyone fall out of their tube so go with whatever feels most comfortable for you.
There are 3 lanes for the tubes, a couple of which can accommodate going double, which means attaching the 2 tubes together. The staff determine when you can go & ask if you'd like a push, a spin or just to let gravity do its thing. The runs are a decent length with a pile of straw and bales at the end to keep you from launching down the river bank! The view of the river is sweet as you get pulled back up the hill on a cable while relaxing in your tube.
We briefly hung out in the lodge at the end of our day and grabbed drinks to rehydrate us after being out there for awhile, there were a few food options as well, but we didn't have any so I can't comment really on the selection or quality/value. They also offer rentals of all kinds for the hill which is great if you are just wanting to try it out for the day. I've seen groupons offered for lift tickets so it could be a very effective and economical way to test it out if you've ever been curious to try skiing or boarding. We had a blast with the tubes and will be back to do it again in the future, the fun we had was definitely worth the price we paid! read more
