https://youtu.be/SNjyz4XqOTM Above is my one day adventure of this trial! It was great! We did some good rock scrambling just above Deer Lakes and into Duck Lake. It was cool! The trail is very intuitive over the pass. So many breathtaking views and sights! Duck Lake has stunning hues of blues and turquoise!

Did part of this trail after coming up from Lake George. Amazing scenery on the crest . Can't wait to go back and do the whole loop.

We hiked up from Coldwater Campground over Duck Pass and wandered up to see how much snow was still there. There is a ton so without ice axe and crampons we were out of luck. I have not hiked this in dry conditions so looking forward to seeing what it is like someday.

Did this as part of a loop, coming back along Duck Pass trail, Emeralds Lake trail and Coldwater George trail. Definitely felt the altitude when I set off but it got better. It was an overall steady climb up and no long strenuous sections. Started hailing and then snowing on the way down. Great views and worth the effort.

I loved this trail. Beautiful scenery and views as well as wildflowers. A bit of a climb, but well worth it.

Just finished this. Took about 8 hours. Lost the trail once I saw duck pass on the ridge. Thankfully this app’s GPS works without service. It saved me. The talus was challenging but pretty solid with minimal loose rocks. There was a gorgeous nameless aqua blue lake before the talus. So amazing. Ps. Took my Siberian husky and he loved it.

Nice hike! However, the USGS map - and this one! - does not show the correct route from Deer Lakes to Duck Pass. The actual route, which can be seen on Google Earth, goes up a hikers' trail through the talus above Upper Deer Lake, and onto a sandy flat area at 11,150'. The trail up the talus starts at about the 10,920' contour. Then you continue E on faint trails until you reach Duck Pass.

I went as far as Deer Lakes, took about 5 hours in, 3.5 back (I'm a moderate hiker, & I pause fairly frequently to take pictures). A good amount of elevation gain. I went in early July & there were a bunch of great wild flowers at the upper elevations. There's a lot of varied scenery & a fair amount of exposure. It's cool to look up at the imposing monolith you see when you start & then be able to look down on it when you're up near the top. There were no streams along the way, so only water was at Deer Lakes. Make sure to go up to the top one, you can barely see it when you view the lakes from the trail as you start descending into the valley. It's absolutely stunning, that cool green color. You see mature trout just cruising through the pristine water. Great to jump in as it's deeper than the lower lakes & fewer mosquitos. Had the whole thing to myself for an hour before heading back.

We climbed Mammoth Crest Trail in Summer of 2013; loved it! The scenery is fabulous! You catch the trailhead at Lake George, and it's a pretty popular and well-traveled path up to Crystal Lake (with a healthy elevation gain too--so breathe!). Just before you get to Crystal there's a cut off that will then take you further up to the ridge. Once you get here, the scenery is stunning. You keep getting higher and get to high meadows and wild flowers. You can stop for lunch here, relax and literally smell the flowers, then head back down the same way, or if you're still day hiking, and you have enough food, energy and daylight, you can keep going and hike down to the Deer Lakes. Then from Deer Lakes you can cross-country it (no path) and meet up with the path at Duck Lake. From Duck Lake you can continue your loop with a gentle downslope (because you did all the hard work on the way up...) coming out at the trailhead at Coldwater Creek. Once you're at Coldwater Creek you will need to hike down to the road, and hopefully catch the tram to take you back to your car at Lake George. This is an awesome hike for day hikers. Not recommended for small children, but for healthy hikers with plenty of food and water. This loop that I've just covered will take you all day so get an early start.

We climbed up to the top of the north end of the crest and then followed a trail to the west overlooking lake mccloud where they do serious rock climbing. Ran out of time but the views of the lakes and back side of mammoth mtn were cool. Not to busy once you pass the crystal lake turn off. Dogs allowed.

First to Review

Mammoth Crest trail is an awesome trail run out of Lake George, most folk on trail kick off at the Crystal Lake trail junction. The remaining 10+ miles you'll have very litl' traffic. Crossing the crest West of Crystal Crags/Lake is enjoyable, once you reach the Deer Lakes area it is off trail routing until you drop down into Duck/Pika Lakes, you can turn around at this point or head up right side/SouthEast of Blue Crags & off trail scramble to Duck/Pika Lakes & return to Lake George via the Barney/Skelton/Arrowhead Lakes trail, at Arrowhead Lake take the left trail towards Bartlett Lake to Lake George.
