Getting There

$5 parking fee, cash only Fantastic views for the effort. The trail up is mostly rocks but not terribly difficult. Great short hike with high payoff. Some people swim at the lake.

On I-70, take exit 238 and head north on County Road 275 for about nine miles. The trail head will be on the left side of the road and requires a $5.00 parking fee at the lot.

Hiked on 1/4, snow was well packed and we were fine with just some low boots with good traction. No spikes or snowshoes needed. The lake was frozen over and thick enough to walk on. We made it about halfway up the glacier and could’ve easily gone all the way up but decided to head back down after it quickly got cold and windy as the sun passed the west peak.

Easy until the lake. Hard if you decide to go past and keep hiking up. Heavy and deep snow past the lake. Wore spikes the whole time. (Jan 4)

Hidden Gem for sure. It's short, but very rewarding. Plenty of trees, wide trails and awesome views. I got up to the pond and didn't get far past that, given some strong gusts of wind and a blizzard. Temperature drops significantly past the pond.

trail and scenery was great - winter weather was a challenge! snowy and suuuuper windy. if you have the gear though, totally worth the effort. didn’t need snowshoes as the snow was pretty hard - did benefit a lot from micro spikes though. I would suggest ski goggles if you have some in case the wind is blowing like it was today.

Snow packed; wear micro spikes. Climbed the center then northern couloir. We wore crampons and roped up but rope not needed. 30+ degree slope was firm with no energy. Snow boarded down the backside/ glacier area.

Make sure to bundle up. The sunshine is nice but it is very windy. The walk back on the ice can be slick so bring your spikes if you wish.

Holy cripes is this a pretty hike! The first piece to the lake was snow packed so it was fine without snowshoes. We put shoes on after the lake though as we climbed up toward and past the glacier and they were super helpful. Just hiking shoes would have been tough with the deeper snow up top.

packed snow, plenty of other people but I wouldn't say crowded. Weather was beautiful all the way to the top. The lake was completely frozen and the glacier had a nice soft top of packed snow, perfect for sledding. Spikes recommended, just to help with traction, but not required. Great way to wrap up 2020, here's to a better 2021!

One of the greatest hikes I’ve ever been on! This is truly a special place to go hiking and I can’t recommend going to the peak above the lake enough. One of the best views I’ve seen in Colorado! The frozen lake is also a ton of fun to play on! The hike up to the lake is okay, a little tough. But the hike up to the Glacier and top of the peaks above the lake is brutal! I would definitely recommend using either ice spikes or snowshoes if you plan on going past the lake. I didn’t use either and was able to hike over 5 miles through the beautiful landscape around the peaks, and even made it up to the peak above the lake. Snowshoes would’ve helped but definitely not a must!

Today we had planned to go beyond the glacier onto James Peak but lots of fresh powder prevented that. Tons of snow on the glacier, micro spikes work snowshoes would be better. Made it to the top of the glacier via some post holing. Still a terrific hike!

No traction needed for me today. Snow was packed but not too slippery. Just hung high to the right and scrambled rocks in my trail runners to avoid snow lol

Went up with boots only. No issues. I’m sure micro spikes may have helped for about 20’ and snowshoes for about 10’. Boots and snow pants with gaiters was perfect.
