The approach to the canyon itself is the crux move right now. The road through Zion Ponderosa is passable to within a mile of the observation point trailhead. The trail to the descent gulley is quite muddy while the descent gulley itself is covered in thick, icy snow. We set a few ropes to safely descend the gulley and the cautious approach ate up a lot of time. Once down in the canyon the snow relented and we enjoyed a casual romp through Mystery. All anchors looked in good shape except for the webbing color (bright red and even neon yellow). Those with more time on their trip might consider replacing these eyesores. Mid-canyon lake was fully dry and we only encountered shin deep water until reaching the spring. Handline to traverse to the spring anchor was also in great shape. Altogether a wonderful time to venture through Mystery as long as you can get through the descent gulley.

Beautiful day with temps in the 70s. Canyon was bone dry up to the springs, which was a 10' swimmer that could be avoided with effort (I didn't but my buddy did). Knee deep wading in subsequent pools. Rappel into the Narrows was coolio with the typical runoff. Tried not to biff it on the moss (succeeded). Had drysuits and used them from the spings to the end. All anchors were in good condition, including bolts and webbing. 3 (half) adults. 6 hours from East Mesa trailhead to Temple of Sinawava.

Beautiful fall foliage. Lake is dry. Swimmer at Mystery Springs and then a couple of deep wades after that. 2 adults, 2 kids, 8 hours from East Mesa TH to the temple with 20 minutes freeing my rope on the mystery springs rap (my rope didn't fall on the other side of the chokestone, but rather, as far as I could tell without ascending, the biner I used for a block somehow got caught near the lip- I used the rappel station that was farthest left LDC) . Nice day. Temp in Narrows was 38 degrees. Water was crystal clear. Glad to have wetsuits.

We took a shuttle to the East Mesa Trialhead. The trail was easy to follow and the Mouth of Mystery was easy to locate. Death Gully was not as bad as I thought it would be. The Lake bed was completely dry. No water or mud until we descended into Mystery Springs. No wetsuits were needed. No problem with any of the rope pulls. Some of the bolts needed to be tightened on the shorter rappels/ downclimbs. All the webbing was good enough. Loved the canyon especially the last rappel into the narrows.

All webbing on rappels we used looked great. A naked bolt at some downclimbable rappels. No wetsuits was fine, though I got chilly after the first pool waiting for my partner to run back to look for a phone. Bone dry to first pool. The first pool (5' long swim) could be avoided with effort to swing around and stay on rock. I didn't avoid it. The second was a ribs-deep walk.

They say it has all been downclimbed except the last rappel. That is INSANE.

party of 6. no wetsuits taken or needed- even by a cold natured thin squirrel in our group who chills easily. The "lake" at the breakdown was 100% dry and just sand. The only wet part was the last 1-2 drops right near the exit drop into the narrows. Briefest of swims in those only. Anchors are good. Placed no new webbing, etc. Great day.

Observation Point trail still closed so we shuttled from the east side. 45 minute stroll to Death Gully and then exactly 5 hours to the final rappel into the Narrows at a somewhat leisurely pace with a group of 6 that included two newbies. No lake. Strong spring flow. All anchors in great shape. Death Gully the same as always.

Cold, but no probs in 4/3 full-body wetsuits. Party of 2, shuttled approach. Started about 7am, made Sinewava about 1:30pm.

Mystery Lake is full. Tiptoes and chin deep on the rdc side. A few other knee and thigh deep pools in the top half. Fantastic canyon.

Great day!!! Mystery is super dry; we didn't get our feet wet until the springs. That's a short swim, then there's a waist deep wade and a chest deep wade after that before the last rappel. Hit the springs rap right at 3:30pm and we were in full sun from the springs to the top of the last rap. Perfect timing (as I get cold easily and stayed toasty warm without a wetsuit, making this my favorite trip to Mystery so far!)

All anchors look good. We didn't have a wrench with us, but it would be worthwhile for someone to bring one through the canyon. There were 2 old/rusted quicklinks on anchors that had been replaced by new links so the old ones should be removed from the bolts. Thanks anyone for your public service. :-)

Great day. No wetsuits needed on our trip. The high that day was about 90F. All anchors seemed to be in good condition. Everything very green and beautiful!

The lake is absolutely dry. Aside from one or two small, foot-deep pools we couldn't bypass, there was no water until the first big rappel. The first big rappel does have a very short swim at the bottom. There is some water in the canyon after that point, but it is chest deep at the max. Water is flowing at low volume over the final rap.

In our group 4 of the 5 of us had wetsuits, which we put on before the final two raps. I can be done without wetsuits, but they were nice to have. The one guy in our group without the wetsuit got a little cold standing at the top of the final rap.

The "Death Gully" is absurdly steep, I hear there are two possible routes down, I think we took the harder of the two. The first slot section is bone dry, nothing but tiny minor pools after the left turn until the springs. The lake is completely gone, not even any mud. I would recommend putting on your wetsuit at the top of the the big 115 foot rappel into the pool, because I was very cold without it and had to put it on after swimming in the pool to complete the canyon without shivering. Fun canyon, although it was more strenuous than I expected from descriptions.

Little wet at the end, a few swimmers, no wetsuit needed.

Made a second round this year; the drive to East Mesa trail is doable by a compact car (Chevy Cruze did just fine) now.

Replaced webbing on two of the bolted anchors. Mystery lake is all but gone. Went from neck deep to nearly nothing in 29 days. Everything is nearly in full bloom!

Group of 4, including a stop at Observation Point, 5 1/2 hours from car to narrows. Fast trip.

Friend left pair of Oakleys on last rappel; love to get them back if recovered! Contact me on please.

-All anchors fine.

-Lake is knee-deep if staying close to LDC wall.

-No wetsuits, only neos; was a bit chilly, but this Viking runs hot, so you'd probably freeze... bring your rubber.

-6 people, 5 hours car to car

-The least attractive run through Mystery to date.

-10% of vegetation is starting to bud... give it another 3-4 weeks.

Excellent trip! The road to Observation trail was muddy and contained deep ruts (8-12"). High-clearance is recommended until it's graded. Otherwise you will need to a walk an additional mile to East Mesa Trailhead.

Death gully was mostly dry. Some patches of snow but maybe 3-4" deep. Some mud on death gully, but most is avoidable.

Most anchors in good shape. Replaced two webbings lengths.

Most raps except the last 3 all had a trickle of water running down them.

Mystery Lake is chest deep and cold. We wore wetsuits and were glad we had them.

6 people (2 noobs) took 7 hours. Death gully slowed us down a bit.

Lost 2 pairs of Oakleys on this trip!! Contact me on if found! Read more here:

Despite being told there was a lake, there was no lake. No water until the springs, then a bit chilly with no wetsuits.

Canyon remains bone dry. First three real repels all screwlinks were partially or completely open! Check them! Replaced one with an obvious threading problem. All webbing was in good condition. Careful getting rope stick on last repel; there are waaay too many screwlinks making it quite a mess even when choosing the newest one; rope was easily stuck. They were too tight to undo by hand and I did not have a tool to remove them. 2 people East Mesa route to narrows walkway 4.5 hours.

Despite recent rains of the false-start of monsoon, bone dry; absolutely no water until the springs.

First four raps entirely avoidable.

4 through, one with a jankle and another a noob, 5 hours car to car.

Also, a snake guards the raspberries; beware.
