The Zion Narrows is a stunning river run in Utah, with challenging obstacles including boulder fields, tight channels, and deep pools. The difficulty of this run ranges from moderate to difficult, and is recommended for experienced paddlers only. The best time to tackle this section of water is during the late summer and early fall months, when the water levels are lower and more manageable. It is recommended to float this river at a flow rate of 150-200 cubic feet per second (cfs), as higher levels can make it more dangerous. Overall, the Zion Narrows offers an unforgettable and thrilling river experience for those up for the challenge.
