This hike starts from Burr Point, a beautiful overlook of the massive Dirty Devil River gorge. To get there, get to the small town of Hanksville, Utah where Utah Highway 24 and Highway 95 intersect. In Hanksville, Highway 24 continues west towards Capitol Reef where Highway 95 heads south towards Lake Powell. Head south on Highway 95 for about 15 miles and look for a dirt road that heads left (east) off the highway. This is the Burr Point road and is in great condition passable to any vehicle. After traveling 11 miles on this road it ends at a small round-about at the top of the cliffs overlooking the Dirty Devil River.
If you have a high clearance vehicle, you can shorten the walk by a half mile each way bu heading south on a small road paralleling the cliffs until you reach the top of the dugway. This road is no longer passable to any sort of vehicle and you will be forced to park at a small camp spot right at the top of this old road that was blasted out of the Navajo Sandstone for miners.Coordinates for this spot are:
From where you park at or near Burr Point, you are standing on the Carmel Formation that was deposited during the Middle Jurassic period around 170 million years ago.
From here, start hiking down the steep dugway trail that takes you down through the light colored Navajo Sandstone. This road goes down for about 1 mile and comes to a fork in the road. Take the left fork and start heading east. After about 300 meters the road ends and a cairned trail starts. Follow the well cairned route down through the remaining part of the Navajo Sandstone and onto the red Kayenta Formation. Continue descending through the Kayenta benches. When you see a large cliff that doesn't look like it can be rappelled, it can't. Look to your right for more cairns that lead you just above the cliffs around the bowl and to a prominent point. By now you are walking on the cliff forming Wingate Sandstone. Very few breaks in the Wingate cliffs are seen throughout Utah.
When you get to the end of the point, you will notice there is a spot for a short rappel of about 15 meters, an existing stretch of webbing that was in good condition when we were there in March 2011, and areas that you can make your own anchor with new webbing if you wish. This is called the Miners Trail and Rappel. The Miners Trail is the cairned route you just followed and the rappel is sitting in front of you. This is a very easy rappel that involves a 10 meter steep slope followed by a 5 meter vertical section. A 20 meter rope is best to use and it's better if it's pretty thick as you will have to ascend back up your rope when you return so be sure it is secure. Leave the rope there and have your ascenders or prusik ropes with you. The chances are slim that anyone else will be here with you on any given day you do this hike and if anyone else is, they are not looking to go out stealing ropes.
When you finish the rappel, descend the long talus slope 500 feet down towards the southeast and get to the Shinarump Bench, a member of the Chinle Formation. The river is still about 400 feet below you but you will follow this bench generally in a southeastward direction and hike around five points in the Wingate cliffs above you which covers a distance of about 2.5 miles. The first part of this bench is easy hiking on open flat rock but the second half of this bench becomes much narrower and you must weave your way in and out and over rocks at times barely skirting cliffs below you.
When you round your fifth point, the bench will open up again and you will come across an old mining track that will continue all the way to the Poison Spring Canyon 4WD road. Walk on this old road for a very short distance and pass a large pile of petrified logs.
Just after the logs, look for cairns and route find down through the deep red colored Moenkopi formation and continue into the lighter colored White Rim Sandstone until you come to the river. This route is also well cairned and generally heads east. At the river, you are standing on White Rim Sandstone which is Permian aged and was deposited about 250 million years ago. That means you just walked through 80 million years of time in the rock record. I just think that's so cool!!! Once you are at the river, you should see a large canyon coming in from the east on the other side of the river. This is Happy Canyon and the cairned route should take you right to it. The river is almost always cross-able here with the exception of April and early May after a heavy snow year. The water may be running too fast during this time but in March 2011 when we were here it wasn't more than waist deep. I would advise taking extreme caution though if you have expensive photography equipment with you as I did. Once across the river start walking up Happy Canyon.
Happy Canyon begins to narrow up very quickly. The lower part of this canyon is by far the best part as much of the large drainage basin is wide open. Keep an eye out on the weather though and don't enter if rain or storms threaten. After only about a third of a mile the slot begins and continues for about a mile. This is a very convoluted, deep and beautiful slot and if you can, take your time heading through it. Since we went in march and the hike both ways is so long, we only got to spend about 45 minutes in the slot and got up halfway before turning around. It is a safe haven from the summer heat if you go in the summer. Here are the photos I was able to get in the slot using a small tripod, a digital SLR and a shutter remote.
You simply turn around when you have had your fill or are running out of time. Remember, you have a long, three stage ascent to do. Return exactly the way you came. When you get back to your rope, ascend it and then take it with you when you leave. Re-climb the dugway back to your car at Burr Point. Sunsets in this area are particularly amazing and colorful. Here are a few I captured from that evening. Once back at Burr Point, head back to Hanksville and reward yourself with fantastic burgers at the Stan's Burger Shack located at the Chevron Station.
I recommend doing this particular hike as a long day hike. You can camp at Burr Point or at the very top of the dugway. If you want to do it as a backpack, remember you'll have to rappel and up-climb your rope with large packs but the best place to camp along the route would be near the large pile of petrified logs. It would be very important you carry enough water for as many days you're out. This is also wild BLM Lands. Please respect the land and leave no trace.
There are alternate routes for someone who wishes to see this canyon but doesn't want to rappel. If you have a very tough 4WD vehicle you can turn onto the Poison Spring Canyon Road that heads east off Highway 95 a little further south of the Burr Point Road and descends steeply into Poison Spring Canyon. When you come to a fork in the road you take the left fork onto the same old mining track. This eventually goes all the way to the petrified logs but can only be driven about halfway to a point where a house sized rock blocks the way. If you take this route, the day hike is much easier but you need to be sure your vehicle can survive!
A third route would have to be a backpack of at least 2 days. From Burr Point you can take a cairned trail to the north of where you would park and descend to the river way the heck north of Happy Canyon, cross the river and follow an old mining track on the east side of the river for many many (about 20) miles as it weaves in and out of prominent points and passes by an old airstrip. This road will eventually cross Happy Canyon at the Upper end of the slot in which you will head down the slot then return back up. I don't recommend this route in the summer as it's a long trek in the open sun. Return the way you came for this route.
