- While the trip can be completed in one day, a peaceful overnight is also possible.
- Descending in the lush canyon, a constant spring provides water for drinking and swimming, as well as the waterfall.
- For advanced canyoneers, the Slickrock Pass Variation has a 3-pitch, 460-foot big wall rappel.
- After descending the canyon, the return trail passes Kolob Arch.
Either as a single day or overnighter, Icebox Canyon (also known as Waterfalls Canyon) is a great way to be alone in the fingers of the Kolob Canyons. Running it as a single day trek will be long and tiring, but rappelling gear for an overnighter can be difficult as well.
While there is plenty of water inside the canyon itself, enough water must be carried to reach the canyon floor, a distance of about three miles. Dropping down into the canyon requires several rappels through the watercourse, which is surrounded by lush vegetation.
After entering the canyon proper, follow the waterway through several more rappels, including one into a large pool, and over a waterfall (hence the Waterfalls Canyon name), while enjoying the vegetated red rock canyon walls and other features.
Although the route is long and technical, the spectacular waterfall finish and a view of Kolob Arch make the long day worth the scratches, aching thighs and sun-burnt face.
