The rental place is conveniently located right outside Zion National Park. It has everything you need for hiking the Narrows (river hiking), tubing and other activities like rock climbing and canyoneering. Also great place for classes, guides. Staff is friendly, patient and helpful.
If you rent the tubes, best to make a reservation since there are a limited number. The company is good about informing people of water levels. We went in June so levels were low which meant it was a rocky and bumpy ride down the river. My husband and I got stuck a lot. Our boys ages 11 and 14 loved it. They embraced the rocky ride and we ended up calling the activity "bumper tubes." The company provides a free shuttle back to the shop.
We also rented boots and sticks for the Narrows the night before our river hike. I recommend doing that to save time.
Next time we'd like to sign up the kids for a canyoneering class.
