Red Rock Canyon permit fee: $10 permit reservation fee.
Three and a half miles down a creek bed to Gold Medal water on the Gunnison, on a permit that lets eight people a day into the whole canyon.
Red Rock Canyon sits in designated wilderness on the southwest side of Black Canyon of the Gunnison and is reserved separately from the South Rim routes. The route is 3.5 miles one way and drops 1,300 vertical feet to the Gunnison River, gradually rather than by scree gully, which is why anglers use it and why hikers pick it as an alternative to the steeper routes.
The quota is the smallest in the park: a maximum of 8 users per day and 4 permits or groups per day, with a group size limit of 4 and a maximum of 2 nights. Peak season reservations open in two windows at 8:00 am Mountain Time, April 1 for May 1 to July 31 and July 1 for August 1 to October 31. From November through April permits are first-come first-served outside the South Rim Visitor Center.
From the Red Rock Canyon parking area on Bostwick Park Road the route begins on a two-track dirt road for the first mile to the trailhead proper. From there it follows a shallow creek down into the canyon.
The route is 3.5 miles one way and gradually drops 1,300 vertical feet to the Gunnison River. It is not marked and not maintained, and numerous stream crossings can make finding the route a challenge. The lower third is thick with poison ivy, which is the thing people underestimate.
At the river campsites become visible upstream and downstream. Use the smallest site that fits your group and vacate by 11 am on the day you hike out so the next group can find a spot.
Every other way into the Black Canyon is a scramble down a scree gully. Red Rock Canyon is a walk. That makes it the anglers' route and the one hikers pick when they want the river without the 2,722 foot descent, and the park protects it with the smallest quota in the park: 8 users and 4 groups per day.
The first mile is an old double-track through ranch country and then the canyon takes over. The creek crosses under your boots again and again, poison ivy comes up shoulder high in places, and then the walls open and the Gunnison is right there, wide and green and cold, with campsites scattered up and down the bank.
Best for: Anglers and hikers who want to reach the Gunnison River without downclimbing a scree gully, and who do not mind wet feet.
Recommended experience: Basic route finding. There is no marked trail and the creek crossings hide the line.
Not recommended for: Anyone highly sensitive to poison ivy, or anyone planning more than two nights.
Trailhead information
