To get to this canyon, drive south on Highway 95 out of the small town of Hanksville, Utah. The highway starts here at mile zero and the mile markers are important to finding the correct place to pull out and park. Continue south on the highway as you begin descending and following North Wash. Once you reach mile marker 33.6 which is only a quarter mile past the Hog Springs Picnic area, you will see a pull out just big enough for one car on the left (north) side of the highway and the boulderfield just above marks the approach. From your parking spot, hike up the boulderfield staying to the left side for easier hiking. After a few minutes you will reach a dryfall which you will need to climb over. From the center of the dryfall, locate a 12 foot slab to the left (looking up-canyon) where you will be able to climb up with 4th class climbing. It really isn't that hard and if needed the first person up can set up a handline for others.
Once above this short climb you'll be at an elevation of 4,160 feet. Cross back to the left side of the drainage and ascend the obvious rock gully heading up and to the west. Be sure you don't head towards the ominous looking slot upstream. Continue up the gully and up slickrock veering right and mount a nice white ledge at 4,400 feet in elevation. Follow this ledge around to the north where you will be able to see the canyon below you to the right. After a quarter mile you can descend to a tree growing out of the canyon bottom. This tree can be used to descend into the slot canyon or you can take Rappel 1 off a sling anchor into the canyon. However, using the tree can save you a wade through cold water at the very start of the slot.
Once inside the canyon begin heading down. The canyon starts out easy but a drop is quickly reached which marks Rappel 2 (unless you down-climbed the tree). This short drop can be down-climbed but most will want to rappel. There is a nice anchor here to use. Beyond this rappel the canyon opens up where you pass by a small grove of cottonwood trees. This section has some really nice and photogenic spots and during the fall the trees will display a bright yellow color.
After you pass through the open area the canyon slots up again and you quickly get to Rappel 3. Here it is off a deadman anchor that we added rocks to. I went first and had Scott back it up for me but it was solid. This short rappel dropped into a pothole but it was dry and filled with quite a bit of sand. This might be filled with water at times so keep that in mind. Only a short walk past Rappel 3 is where we ran into a pothole drop with water in it. A 10 foot down-climb led into a pothole that likely has water most of the time. If you dropped right into the water after descending it will come up to your waist however there is a small ledge on the left side (looking down canyon) about a foot above the pothole you can use to avoid part of the wade (or avoid it altogether if you're really good...the final part of this ledge disappears). Using the ledge and sliding into the water halfway across makes the water only knee deep. Either way just about everyone will have to wade. Once everyone is across take a few minutes to dry off.
Take a single 40+ meter rope. This will be long enough for all the rappels in the canyon, the longest of which is 60 feet (~18 meters). Also make sure you have harnesses, belay devices, extra webbing and rap rings and helmets. Know how to construct or improve deadman anchors as flash floods in these canyons can destroy or compromise existing anchors. Gloves are also nice for rappelling. Plan on 2-4 hours for this canyon depending on your group size and how fast everyone can rappel.
