Canyons are inherently risky. Flash floods occur without notice on sunny days. Technical skills & surrounding topography knowledge required yet does not eliminate risk.
A forested limestone canyon
Kelly canyon is a beautiful canyon located about ten miles south of Flagstaff.
You'll want to do this hike in the spring through late fall due to snow in the winter months.We did this hike in June to take advantage of the cooler temperatures near Flagstaff. To get there take I-17 south out of Flagstaff about 10.5 miles and take the Kelly Canyon Rd. Exit. Turn right onto Kelly Canyon Rd. and drive for half a mile until you are at a stock tank. Take a right (north) off the main dirt road you are on and proceed until the road splits. Here, if you take the road to the right you will drive about .2 miles till you come to an old cabin on top of a hill, you can park here like we did and walk down into the drainage leading to Kelly Canyon. Another option is when the road splits is to keep going straight until the road starts to go up and park here, this will save you about an eighth to a quarter mile in distance you'll have to hike to get into Kelly Canyon. After following the drainage north, you will come into Kelly Canyon. Take a left and start down, there's a game trail just when you come into the canyon on the north side, but I wouldn't recommend it because it takes you up and away from the canyon. There is a trail through the creek bed that peeks out here and there. The trail does get better a little ways down the canyon and eventually becomes a mountain bike trail that crisscrosses the creek.
Upon doing some research before we set off to this canyon we found that it is also home to "Rock Jocks" and the evidence albeit slight is there, you'll notice the chalk on some of the walls when you head down the canyon. This presence is less and less as you head down the canyon. I guess this place is pretty popular for rock climbers, but we saw no one there and no trash, just some repelling rope stashed in a small cave. As you make your way down the canyon try at least some of the time to stay in the bottom otherwise you miss some of the cool rock features along the way. Water is scarce here unless you're here in early spring with the snow melt fed creek. There were some small pools of water, but you'd have to do some filtering if you wanted some.
You'll know you're at the end of the canyon when it ends at the confluence of Pumphouse Wash, which you can head to the right and meet up with FR237 or take a left and continue down Pumphouse Wash all the way to Oak Creek canyon. You could also meet up with James Canyon as well on your trip down. If you have a good eye you can see some very old pictographs and petroglyphs on some of the rock walls along the canyon.
The canyon floor was full of wild flowers, wild rose (Fendler Rose),Morning glories,Rocky Mt. Iris, Yellow Columbine and more. The greenery was beautiful, Lady ferns formed a carpet between the Ponderosa Pine trees and Douglas Furs. Some Aspen trees were along the canyon floor. Lizards, to numerous to mention scrambled everywhere. In the pools you will find Salamanders, Crayfish, and Tadpoles. At the confluence of Pumphouse Wash, we found Garter snakes in and around the pools of water.
