Westwater Canyon is the first whitewater stretch on the Colorado River in Utah. The canyon is 17 miles long and includes Class IV rapids, is challenging at all water levels, and is only recommended for experienced boaters. As with any remote river section, Westwater can be a very humbling and dangerous place if not treated with proper respect and ability. Due to heavy recreational demand and to protect the primitive nature of the Canyon, permits are required year-round for private and commercial use. Between April 1st and September 30th, private use is limited to five permits or 75 people (whichever occurs first) per day; commercial use is limited to 75 passengers per day. From October 1st through March 31st, use is limited to seven permits or 150 people per day. Permit fees are NON-REFUNDABLE.
