Hades knoll is a promontory in a remote and unforgiving section of the northern Grand Canyon region. 30 miles east from toroweap Hades knoll is also home to the longest narrow slot canyon in the Grand Canyon.


 Hades Knoll Canyon has a long 10 mile approach just to get to the beginning of the canyon from the trail head.

The hiking from the trail head is more like a prairie of sage and juniper trees until you get down to the esplanade, where the terrain changes a bit more to a desert environment with prickly pear cactus waiting around each corner as you step.

The hike to Hades Knoll is relatively flat but the distance to get to the trail head comes with a dry and Barron landscape devoid of water.

make sure you bring the right portion of water with you and a little more.  I brought 4 liters and I almost ran out of water, luckily there are some static pools in Hades Knoll to filter water from.

The trail along the sun baked esplanade disappears and navigation is a critical component so you minimize the impact of the crypto soil and to save valuable hours on the approach to Hades Knoll.

After about 6 hours of hiking, we made it to the head of the canyon and looking forward to hiking in some shade and cooler conditions.

The upper part of Hades Knoll had some vegetation and minor down climbs. The canyon walls came somewhat close and eventually opened back up into some large canyon gorge passage.

We had a few more down climbs and finally got to some water. After spending some time pumping water, we continued our way down into the red wall limestone.

This is where the canyon started to get interesting.  We encountered two mandatory raps up to 40ft in length and some downclimbs.

The canyon walls were varnished with corrosion residue and appeared to have a few blind karst windows within some of the faults.

At the bottom of the first drop, there was some interesting conglomerate stone matrixing within the redwall.

We had a decent amount of time in the canyon until the sunset so we were able to enjoy the long stretch of narrow canyon with the sun casting a beautiful maroon to fiery reds and oranges as we cut around the bends.

The hue of the sunset started to set in and accentuated the bright reds and oranges within the canyon until the sun started to set.

We encountered a lot of down climbs and a few where we had to provide a partner assist.

There was also some interesting karst features within the canyon with some holes in the walls and a beautiful grotto cavern with dripping water and a massive flow stone in the entrance.

The cavern did not appear to continue so it is more of a deep alcove like feature but it was one of the highlights.

not really sure what Yannick is trying to do.

We continued on and the sun started to set.  The colors started to turn into a purple blue color and eventually faded into the darkness where headlamps became a necessity.

We had some more down climbs to negotiate and once we got close to the confluence, we had a 50 ft dry fall that we have to walk around from the top.

The frogs sounded like mountain goats as they echoed their calls through the tall corridors of Hades Knoll canyon and into the Tuckup canyon.

after leaving the trail head at 7:15 we made it to the confluence in about 11 hours.

We claimed our spots on the slab rock and set up camp for the night with kitchen quarters and a sleeping area for both the sawmill snorers and non snorers.

We cooked dinner and enjoyed the perfect conditions that the moon and the weather provided, so much so that some of us took off our shoes.

Justin and I were sitting next to each other and he all of sudden looked up and than jumped up.  I saw a scorpion run away into a crack and than we heard Justin say that he got stung by the scorpion a few times.

he was in a lot of pain at one point got on the ground and started dry heaving a bit.

Some people can have a different reaction to scorpions than others but the pain usually lasts 12 hours with the first hour being very painful.


Justin was in bad shape, I started to look around for more scorpions and scanned the area to make sure we don't have any repeat attacks.

Into the night I could hear Justin in pain and he mentioned that his vision was a bit blurry.

  I told him that we will leave the canyon and head out so if he has any secondary issues that arise we will be able to get to the hospital.

This is not the place where we want to have a medical incident happen and even though we had a spot with text messaging service, i want to minimize the risk so we headed out the next day.

Hades Knoll is quite the canyon as it has a long stretch of narrow corridors with some interesting geology and beautiful scenery but it comes with a price with hiking to a remote section within the tuckup trail region.

Daniel down climbing in Hades knoll.

Be prepared to bring extra water for the hike and even though we went in some pretty good conditions in April, the hike was quite hot on the esplanade with little shade.

Hiking out of the canyon in the tuck up provided similar views and some great geology but Hades Knoll did have some unique features and is the worth canyon to visit.

I recommend getting a early start from the trail head and sleeping at the trail head the night before so you can take advantage of the cooler temps and not have to drive on the road.

The end of Hades knoll canyon.

We finished this canyon in a long day and had every intention to go to the river the following day and than hike up to the esplanade and down rocky point but we ended the trip to ensure the safety of the crew.

Don't walk around the slab rock at night without any shoes or you might end up like Justin !
