The trail is well labeled and easy to find due to the traffic it receives. The weather during the summer is unpredictable, and it is recommended you are back below tree line by 2pm due to the risk of thunder storms. The most difficult part is doing the boulder field, however if you take your time most people can navigate it without trouble. The view from the rock formation keyhole is incredible.

Wonderful hike. Start early, 3:30 am, then have breakfast at the keyhole before ascending the summit.

Beautiful, but got a little altitude sickness and took a tumble on this trail, fortunately not a terrible tumble and was able to continue. This was part of a hike-in camping trip, pretty cold at night.

Attempted hiking this on 10/7. While I started at 3 am, I ended up suffering altitude sickness on the stretch just a few steps from Granite Pass. Although I took 3 hrs to get to the turnaround point, the sunrise was stunning and worth it. 7 people passed me on my way up and I can only imagine heavier crowds in the summer. The tundra winds were fierce and recommend something to cover the mouth. (That said, the snow storm that blew in recently affects latest conditions) Can't wait to try attempting again

Trail in good shape. Bit of snow and ice in trough and home stretch but mostly avoidable. Bizarrely it was perfectly calm on summit despite 40 mph winds forecasted.

9/30 It’s pretty snowy past the keyhole, but I managed to summit in sandals. Still very doable as long as the weather allows for it.

Went to the Keyhole on Sep 1. This was a training hike with 40+ lb pack, so I had never intended to summit. Still slightly disappointed, but I’ll be back soon enough. My advice to the complainers who fuss about trail traffic... stay home. There’s a reason why this is so popular. It’s an epic hike, high quality trail, with amazing scenery. And other than limited parking it’s very accessible. If you do make the trip, forget about solitude and just enjoy the moment.

One of the best 14ers out there. Well marked, relatively difficult, beautiful views. Gets busy so wake up 3am and start.

Did this over two days on 9/18 and 9/19 as I camped at the Boulderfield. Coming from Massachusetts I had also camped the night before in Estes Park to get acclimated. Took about 4.5 hours carrying a 50 pound pack to get to the campsite from the trailhead. After setting up camp I used a JetBoil to boil water that was collected from a slight stream about a quarter mile down trail. Was the only one camping overnight, which was a little worrisome. It’s very windy at night at the site. Woke up at 6 am to finish off the peak with just a daypack. Narrows isn’t as exposed as anticipated. The trough was the hardest part. Coming down the Homestretch is also tough. From a time standpoint it took about 11.5 hours of actual hiking.

Really great views of front range and RMNP. Nice trail, easy to follow. Made it to keyhole in about 3 hrs. Too windy to summit. Blowing at 40-50 kts. Added Chasm Lake instead. Will try again next yr.

This is a brutal hike and if you aren’t fit or used to the very little oxygen up there good luck. We started the hike at 2:30am and still didn’t have enough time to make it to the tree line before noon. And the hike actually starts after the key hole.

15 hours. Homestretch going down pushed me out of my Comfort zone, but the narrows was amazing!

*Keep in mind this is 7.4 miles each way and makes for a long day for those with minimal experience* 9/19/19 and the trail was completely dry except for a small icy patch in the trough that is easily avoidable. I had on a windbreaker from the get-go (a late start at 6:30 am) and it was a life saver passing the Keyhole with intermittent 20-30 mph gusts. Minimal passing precipitation during the hike with freezing precip around 2 pm on the descent from Keyhole and a few drops of rain around 4 pm on the descent back into the forest. Overall hike took me about 10 hours with stops and my ankles and knees were definitely feeling it on the descent. Views make it all worthwhile! Easy, paved access for any vehicle type with restrooms at the trailhead and at several points along the hike

9/16/19 the trail was completely clear and dry except for one small section of ice in The Trough, which is completely avoidable if you stay left. The Trough is by far the worst part of the ascent. The Homestretch isn't that bad going up, but is the sketchiest part coming down. the pictures make it look narrower than it is. There is ample room for safe two way traffic.

This trail kicked my butt. It was also the best hike I've ever done. The first few hours I was alone in the dark and it was pretty rough. It's a steady steep incline the whole way with no break but it was manageable especially if you are acclimated to altitude hikes. The boulder field and summit climb are extremely challenging even more so on the way down. Your knees and ankles will probably ache a bit (or alot in my case) on the way down especially the last few miles. The views all the way are incredible but the view once you pass through the keyhole...I was moved to tears. Truly beautiful and worth all the hard work. We had a perfect day of weather too! Not a drop of rain. Started around 5 and ended at 5 so 12 hours with lots of breaks for snacks with a view! Would recommend this to anyone looking to challenge themselves!
