Even with the haze of recent fires, this hike offered some of the most incredible views I’ve ever experienced on a hike. The first couple of miles are pretty monotonous switchbacks through the woods, but isn’t too difficult. Once you finally break out of the tree line, you have an unobstructed view of the mountain that you parked next to at the trailhead. It’s INCREDIBLE! Beautiful, immense, just breathtaking beauty. We took a bunch of panoramic pictures even before the pass, it really was that strikingly beautiful. The views at the pass itself were amazing as well, but the haze was thicker there, still great views but in photos will look a little obscured. We continued onto Doubtful Lake, and that required some additional steep hiking. As the poster a few posts below noted, the trail to Doubtful Lake is not maintained and is STEEP and narrow, and overgrown in a few spots. But certainly doable if you take your time. The lake itself is great, very serene and clear. If you just want photos though, take pictures from above and save yourself the steep hike back up; its hard to capture the immensity of the mountain that feeds the lake from the lake itself. Overall, even if you just hike to the pass, do do DO it! It’s great!

This hike is long and strenuous but the vistas along the way and at the top make the trip a must!

Spectacular!!!! There was smoke from the fires but none the less excellent hiking... 8/9/18

Fantastic hike with challenging elevation, well worth with 360 view at the top

We went from the base of the Cascade Pass Trail to Doubtful Lake and back. Let me just say, it was incredible! There were very few people there, which made it much less crowded than other big hikes in Washington (such as Rainier). We saw a black bear and several chipmunks, and there is hardly any snow left. The trail to Cascade Pass can hardly be considered difficult (though the switchback do get monotonous), but the trail down to Doubtful Lake is much less used and very very steep. However, I would definitely still recommend it. The water was so clear!

Great trail, camp grounds at base aren’t very level but are sufficient. A great view at the top of the switch backs. Going before June is dicey because the weather is still foggy and unpredictable.
Enjoy the beautiful views and naturalism.

Backpacked and camped at glacier camp. It was amazing. One of the best experiences I’ve done

Did this hike last week and was blown away. Started at about 9 am with fog lacing the switchbacks. Saw pika, marmots, mountain goats, and a black bear and her two cubs on the way. Fog broke perfectly in time as the trail curved towards Sahale Mountain from Doubtful Lake. Perfectly clear for pics the whole way down. Insane. Overall, mellow grade - a long & perfect day hike -

Very good hike with enough elevation gain to be challenging but still manageable. The view from the lookout afforded pretty amazing views in all directions. The one drawback today was the available views were a bit diminished in clarity by haze from forest fires. Bugs were annoying but not dreadful on the lower reaches of the trail.

We tried to get an overnight permit but it was full (same thing happened to us 2 years ago). We were at the Ranger Station at 630am and 7th in line, but it seemed people had reserved it long before. We shook off the disappointment and did it as a day hike, and ended up happy we could do it with just our light packs. Some of the most gorgeous views in the Cascades. The difficulty up to Cascade Pass is only moderate (many switch backs but low grade), but after that there are some steep sections, especially the last little scramble. The views are well worth it and surround you as soon as you get near the pass. I’m lucky I didn’t trip more as I spent all my time looking around me and not down at where my feet were!

If anyone sees an Orange REI rainfly laying around on the road somewhere please contact me at cranswic@hawaii.edu... lost on July 24th

The hike was GREAT! Totally gets your blood pumping and then the views take your breath away!

My favorite hike in WA! Bring bug spray and get there a little early to get a good parking spot.

Awesome trail! It is rated correct as hard. It’s no so much the length of the trail as much as it’s the up and up and up some more. There plenty of water on the trail and snow. I found it was easier to cross the 4 snow packs with my crampons as my knee was not liking the unstable surface. Views were AMAZING! Lots of wild flowers and water falls. You will not be alone I. This trail for long. It is very busy but not over crowded. Parking is a problem if your not there by 8 a.m. at the latest. In the way down cars were parked for a half mile making the already super narrow road worse. Enjoy the hike, take pics

Awesome trail! The views from the lookout are breathtaking. Just make sure to get to the TH before 0800. Parking is very limited. We luckily squeezed into a spot, but by the time we left, cars were lined up along the side of the road (extremely close to a steep ledge as well) for at least half a mile. Besides the parking, it is a great, diverse hike! Would love to go back and be the lucky one to snag the lookout for the night.

July 14, 2018: Amazing hike!
Road to trailhead is rough leave your Bentley at home.
Most of the trail is straight forward. Snowy parts higher up are easily navigable without fancy gear. The summit is kind of awkward since it's all boulders. The climb between the snow field and the summit is interesting, it's steep and the trail is faint in various parts and can be difficult to find, but it's doable for the average hiker. The scramble at the summit isn't that bad.

you dont need high clearance/4wd when the road is dry, but it definitely takes some slow speeds and maneuvering. it's also pretty steep and there's only room for one car most of the time.

as for the trail, it was gorgeous! lots of wild flowers waterfalls, 360 views once you get a couple miles on. there are a lot of water crossings and at some points the trail was more of a creek bed so I definitely recommend waterproof shoes.

This hike is really hard. As someone that lives in Ohio where we don’t have much elevation gain. This hike kicked my butt but it was so beautiful. I had trekking poles to help through the snow but my bf didn’t. We both did fine.

Awesome hike. Downloading the gps was helpful over some of the snow patches as none of us in the group had done this one before. Seemed like most of the snow would melt soon. Trekking poles would have been helpful but managed without.

Rocky bumpy road to the trail head recommend a high clearance vehicle but not needed if you want to risk it. Starts with a nice wooded area and the switchbacks continue through the meadows with nice flowers until you hit snow. Even though it can be done without spikes it will be nice to have them and my trekking poles proved vital in the snow. Once near the lookout prepare to climb over big boulders leading to the lookout. Once at the lookout you will have some tiny visitors looking for a snack. Totally worth the trip for an amazing unforgettable view. As of yesterday July 4th the lake was quite frozen with some snow.

My wife and I took our twin daughters in Kelly Kids carriers as far as we could go without snow spikes and axes as well as factoring in overall safety. Had to turn around at about 5800' elevation when it got too step and slick for us. Until that point the views were incredible. Wish we could have had a bit less snow so we could have seen Hidden Lake.

Gorgeous trail. Generally not that difficult, just uphill. There are a couple of log crossings on the trail that were slippery and precarious. Hiked on 7/3/18 and trail was snow free for the most part up till the traverse to the pass. We used spikes and didn't feel they were too precarious. Definitely doable without but I'd recommend them and poles. Road to trailhead is closed 3 miles from trail so it made for a little over 14 miles to the pass and back. Road crew indicated that they hoped to have a lane open for the holiday but based on what it looked like on our way down I'd say I'd it is open it's definitely going to be high clearance only at points. Recommend bear spray, we saw 3 on the hike up near the pass (mom and two cubs)

The switchbacks feel like they go on forever, but once you come out of the trees the views are stunning. I'd recommend at least continuing up to Doubtful Lake from Cascade Pass.

*** Hey Tray Edwards- the author of the WTA report from 6/24/18 might have your micros...

I drove up late Saturday night to catch the sunrise at the peak. The unimproved road leading to the trailhead is a little washed out and may be an issue for low clearance cars. Although I did see a Prius parked up there. I started the hike around 230am and didn’t have any issues with staying on the trail under darkness, it’s pretty established and no snow until about 2 miles up. You’ll cross a few creeks along the way but nothing too drastic. Once I hit the snow I put on my micro spikes ad had my ice axe available due to the incline of the trail & hard snow. I found it difficult to follow the trail (others tracks) and veered off course a few times and ended up cutting up to the peak earlier than I should have but it was a great view when the sun started coming up. I made it to the center lookout point by 0500ish and watched the sunrise. There were a few campers still in their tents there. The lake is still iced over but it was still a perfect view. After hiking around to the lookouts I began my decent around 0600. The snow was already starting to loosen up and I ended up losing a micro spike along the way. On the way down I was able to enjoy the views I missed coming up in the dark, with beautiful wildflowers and waterfalls. It was a great hike & id love to stay at the lookout overnight next time. Definitely don’t underestimate this hikes difficulty, especially in the dark.

This is my favorite hike within driving distance to Seattle. I haven’t been since last year but am planning a return this summer. Stunning views. Definitely a climb but not difficult like Lake Serene. ❤️ this hike!

My very favorite hike to do in Washington with absolutely amazing views. I highly recommend this hike!

Great hike! Still a lot of snow. Can almost park at the trail head as of 5/12/18

This must be one of my favorite, if not "the" favorite hike - it has really just about everything: an adventurous drive to the trail-head (more on that later), a forest to start your hike in, a lush mountain meadow, plenty of snow-fields (mid July) all the way to a rock-scrambling part to the lookout at the end. And the views, oh my, the views. Going up, they are beautiful already but once you make it to the ridge that will get you to the lookout, you're in for a real treat. I just wish we had known that it was possible to stay overnight in the lookout - sunset and sunrise must be absolutely stunning from there.
The hike itself is not easy and the last part would be tough for people with vertigo but otherwise we didn't think it was too difficult. It's easily manageable in an afternoon even if you take plenty of time to soak in the views at the top. We saw a bear and a pica rabbit too.
Oh, and I almost forgot, the drive. I saw cars parked at the trail-head that had pretty low clearance, so it must be possible to get there in just about anything but I was really happy that we took a rental 4WD SUV. The forest road is quite steep in places and littered with potholes large enough to break your axle in, so having a higher clearance vehicle comes in handy.
Overall, if there is just one hike you are going to do in this part of the park, make it this one!

Incredible. Most beautiful hike I’ve ever been on in the US so far.

Hidden lake lookout. Attempt number 3. Success.
It was king of challenge for me, I tried to get to the lookout two times before (May and November), two times in snow, two fails.
The initial plan for today was relax and enjoy snowshoe around Artis Point, but yesterday evening when I was checking reports I found on alltrails.com that somebody put 5 stars for Hidden Lake trail 5 days ago, it was enough for me to change my plans and try Hidden Lake again. Despite great weather I was not sure if I can make it, I still remember how much snow and avalanches was in May, but I decided give it a shot.

Came to trail around 10:30, actually I didn't get to trailhead even on AWD and parked mile or so before TH, 6 or 7 cars already were there. I reached TH in 40 mins and tired, it was difficult to go by snow, decided put on snowshoe after forest part. Forest part was easier, since less snow there, you can do in hiking boots, but gaiters recommended. Met two people going back, they done forest part of the trail and turned back.

Once I reached basin area I starded to follow by ski track, it was not easy, but doable in snowshoe which is a must at this part. I folowed ski track by right side from the stream, when actuall trail goes by left side. There are few avalances already came down, snow looks stable and solid, but anyway pay attention. Clibmed up to second avalanch, which came from the top and turned left to actual trail. Then did couple switchbacks and crossed this avalanch again toward to travers part of the trail. Despite hard and stable snow it was little bit scary to walk by avalnches, but I decided to go, maybe not too smart.

Travers part was very nice and much easier! View was gorgeous, clear views of peaks around, mt Baker, sun, snowshoe. Btw there are some steep slopes on this part as well, I even used iceaxe to go throug it, but as I said I followed by ski track, maybe it possible to find less steep route.

Once I reached end of the travers part I saw many snowshoe footprints at this point I realized that it should be some winter route. Definitely! I've seen many cars but met only two people, and ski track I followed by was few days long.

From this point there are few snowshoe trackы - first is regular trail, second goes to hidden lake peaks. I climbed up by second one, but at this point I did't know that it goes to the peaks, i realized it lated once I got closer. I didn't get to the peak, because it was already 2:30 pm and I had not so much time. I turned right towards to the lookuout, getting closer I've seen some people doing travers by peak to the lookout. In some report guys called this part "do it or die", kind of true :)

So, I reached lake viewpoint, then I took one of the snowshoe track up, travers part to the lookout is very steep, if you will go there you need to be very careful. I put of basket from my right pole and used it as iceaxe, before doing next step I put it deep in snow.

Finally I reached lookout, there were five people and two dogs, they came for overnight. They told me about winter route, it is shorter and much steeper. But! it much safer from avalanch standpoint since it goes through forest and there less snow now. So, if you go tomorrow or before next snowfall you can go by regular route, after snowfal basin area will be risky, but you can try winter route. But as I said it is very very steep espesially at the beginning (from road to lookout)

I took some food and photos and went down by regular route. Yeah, views were just awesome!

On my way back I met three people going up, they came by regular route as me. So, I tool winter route back, first half was easy, since I went down, moderate level of snow, good snowshoe track. Second part was more tough, slopes were much steeper, lots of fallen trees, I lost track little bit, because snow disappeared and I just followed direction to the road. Finally I reache the road, walked down to my car and went home.

Finally I can cross Hidden Lake Lookout trail in my list as completed.
