If you are itching to do a 14er and failed to win the Whitney lottery this is the hike to do. It is one of my favorite hikes to date and will definitely do it again.

Camped at high lake a couple days ago. Nice campground. No issues with marmots. Mosquitoes are vicious, so much that we summited on day two via new army pass (old army was still risky due to ice/snow) and packed up to head back down that evening due to the bugs; and fires are not allowed. That aside, beautiful scenery. Saw some deer, plenty of marmots and I finally got a good look at 4 big Horn sheep. There's ice/snow up there still but nothing you have to trek through at this point. Night temp was low 40s. Thankfully altitude didn't affect me this time like when I did Whitney. Camping at altitude, staying hydrated and keeping a comfortable pace (I feel like fatigue heightens the affects of altitude) made the difference for me. I would do it again. Have fun!

This hike was so beautiful!!
We backpacked the weekend of May 26!
We had to take new army pass because old army pass isn’t maintained and I think it was covered in snow passed lake #3. We were told by the rangers that it was impassible.
New army pass has beautiful views! I loved it!! We camped at high lake which was pretty secluded because most people camped at long lake.
Unfortunately we were not able to summit due to ice at the top of the first peak. I would recommend bringing crampons or micro spikes if it’s still snowy up there! Other people made it without the spikes but it’s pretty dangerous to do so! We chose not to risk it and turned around.
Either way I still loved it and want to try again soon!

Nice, gradual trail with beautiful lakes and striking mountains all around. We started out on the cottonwood lakes trail, then turned off on New Army Pass (as Old Army Pass is currently impassable). We camped overnight at High Lake (~11,500ft), the last lake before the hike to the ridge. It took us a little less than 5 hours to reach High Lake carrying fairly heavy packs. We attempted to summit mount langely this clear Sunday morning (5/27/18); however, only made it just below the ridge (~12,200ft). We didn't feel comfortable hiking the 50 or so yards up the steep icy/snow slope to the ridge without crampons. We witnessed both some hikers turn around here as well as others take the risk and make it up fine. Going up was not as much our fear as going back down it -- as the edge of the icy slope didn't look forgiving ☠️. We do not recommend doing this section without crampons, but it's totally up to you and your comfort level. As always, proceed at your own risk. Hopefully the others made it back down this section safely!

Overall, we enjoyed our overnight backpacking trip on this gorgeous trail and highly recommend. We plan to return in July or August to do Old Army Pass and summit mount langely for real this time. Enjoy and good luck!

I've hiked this route about 3-4 times and love it! My favorite spot to camp is at the biggest Cottonwood lake. Beautiful! Fairly easy getting into the Cottonwood Lakes basin. The trail is nice and very easy to follow. From the lakes to the top of Langley can be a challenge. Definitely prefer Old Army pass as is detailed on this map as the trail tops out in the bottom of the pass. But I've had to go around by Long lake and up New Army pass a couple of times due to snow conditions on Old Army pass. Going that way means you have to go up and over and down from a ridge, which means on your way back down from the peak, you have a substantial uphill once again. But when the Old Army pass trail is snowed over, it's better than nothing. The last bit to the top of Langley is a scramble through the scree and route finding through the boulders. Coming down the scree field can be fun, though. Some of my best backpacking memories are from this trail.

I climbed Langley by way of a loop backpacking trip.

Did it as a day hike. Much better done if you go up New Army pass and come back down Old Army Pass. As of late Oct, there was no snow along the trail. The trail is mostly well defined and easy to follow. The last 0.5miles is off-trail and involves some class 3 scrambling.

This was a great trip! I did it in two days and base camped at Long Lake. The trail is very well maintained all the way to the top of New Army Pass. After that, you're on your own but many people summit the mountain so a trail is pretty well worn in the rocks and their are cairns everywhere. The day I went, we saw a herd of bighorns grazing on a high plateau. It's a beautiful trip and I recommend it for everyone interested in the eastern sierras

2- day trip...base camp is High Lake. Then to Mt Langley summit. Snow packs above high lake and beyond. Great weather and hike. tough at the top.

Hard. I recommend you get used to the elevation first before going all the way up. The body is getting less oxygen so everything- moving climbing hiking lifting- are harder. Lots of wildlife on this trail.

Even though it rained on our hike in, this was an excellent hike and a great experience. Breaking it up into a 3 day backpacking trip made for good acclimatization and very enjoyable trek.

Difficult. If the distance doesn't get you then the elevation gain at the end might. If you feel good going into the final ascent, make sure altitude sickness isn't slowly settling in.

ABSOLUTELY BEAUTIFUL HIKE the entire way through. We started at the New Pass Trail to the peak and saw Mt. Whitney.

We changed up the way back and took the gnarly switchbacks to and through The Cottonwood lakes, all the way back to the car at the campsite.

If weather is good (absolutely NO snow or ice) I highly recommend looping through Cottonwood lakes.

All in all a great an exhausting day :)

2nd 14ner in a week. Much more peaceful than Whitney. Less crowds, great camping. Caught some fish. Hiked to Lake 3, set up camp. Summit the next day. Saw a herd of Bighorns on the way to summit. We went the Old Army pass, shorter, and the trail was in good shape.

Took 2 days (July 24-25, 2015) - The weather was perfect both days. We camped at High Lake and started up New Army Pass before sunrise. Views were stunning all the way to the summit - Long Lake, Cottonwood Lakes, great Western Divide and Mount Whitney to name a few. Made it from the base of New Army to the summit in about 3 hours. Well worth it to hike this 14er.

Great views and a good hike to the top. Mostly class 1 with a very small section of class 2. On our way down we saw about 14 or so big horn sheep. We base camped at Long Lake another beautiful place.

You have to put in some pretty significant mileage for a dayhike – about 6 hours up and hours down in August. The scenery around the luxuriant grasslands of Horseshoe Meadow and the Cottonwood Lakes Basin is gorgeous.

Easy hike through Cottonwood Lakes and New Army Pass, but the painful part was hiking through scree field from the base of Mt. Langley to its summit. Beautiful scenery, lots of wildlife viewing and good fishing.

Hiking Mt. Langley was on my list for a while. Completed it in mid August as a multi-day trip. Drove in and hiked to Cottonwood Lake 2 to camp. Climbed Langley the next day as a day hike. Started leisurely at 9:30am, summited at 2:30pm via New Army and headed back via Old Army. I really would recommend a multi-day trip because the views are just incredible and its refreshing to just stand (or sit) and take it all in.

June 29th 1230am start 230pm finish. 24 mile lollipop route up new army pass to summit and down army pass. Army pass had snow in three spots with big boot tracks that made crossing easy in the afternoon, could be icy in the am. Long sandy slog to the summit block where the trail disappears and it's just boot tracks everywhere. We ended up heading straight up over some tricky class 3 sections with some exposure. Better routes can be found further left (west). It's a very long day hike, including extra mileage to the south fork lakes.

Really enjoyed this trip. Did it in early October after the first good sized snowfall. Camped at Cottenwood Lake #3 and used Old Army Pass, with ice on the trail. Kept it interesting. Found a herd of bighorn sheep on the trail and fresh footsteps of a mountain lion near the peak in the fresh snow. Memorable hike in all regards.

As the prior reviewer mentioned, Langley is a great alternative to Whitney without the crowds.

This is a great Hiking alternative to Mt. Whitney with far fewer people.
The first few miles from the cottonwood lakes trailhead is very easy with very little elevation gain,
and was a little rocky up to the pass, the next couple of miles is quite nice up to the final summit push where some scrambling is required to reach the top.
We went up via Old Army Pass and retuned via New Army Pass for a 25 mile Lolipop loop.
