Wow...awesome sights! Very popular trail, so go early.

Great with kids!

Great short hike with fantastic views.

Great hike and beautiful views

Went while it was 57 degrees and rainy and I would do it again. The view through the fog was spectacular and the wildflowers were gorgeous. Will definitely go again, maybe when the suns out.

Great hike

Love, love the view!!!! Its a steep climb up with lots of people on the trail which was nice since there are three times you could go right or left with no sign. We also learned there was a waterfall which was flowing compared to others in the area. The lake is beautiful and cold but that didn’t stop people from jumping in. I hiked this trail with my 7 & 10 year old and we spent about 2-3hrs enjoying the view, lunch and dipping our toes in the water

Not easy the first 1/2 mile! Definitely worth the effort. Get there early! Bring cash for parking. Main lot is $5. Other lots are $10.

What a beautiful area. Especially great hike for folks coming from lower elevations. Unfortunately, tons of trash along trail and by the glacier. Please, please, please, pick up your trash!! My daughter's boyfriend found a plastic garbage bag left on the glacier and we picked up as much trash as we could going back to the car. Another bummer was that several drones were noisily flying around the lake. I know they can be fun and take great pics, but most folks would rather you leave them at home please!

I’ve stayed in a cabin that I adore up at St. Mary’s Glacier. I’ve hiked the trail to the glacier many times. The trail is short, fairly rocky, and the way to the glacier is all uphill. However, it’s definitely worth the hike. Plus, your hike back is all downhill! The lake is beautiful, and the water is crystal clear. There’s also a hidden waterfall tucked away just to the side of the trail! I just wish it was a little less busy. It seems best to go early in the morning or just before sunset if you go during peak season if you want some privacy. The winter is harsh, but also gorgeous and you can definitely enjoy the sounds of nature!

Beautiful hike. Very rocky but the views were stellar

Stunning views!!! Made it all the way in a Subaru Crosstrek but next time will bring a truck. The last 0.3 was especially rough. Tried our hand at fishing but had no luck...one bite all day. We saw a lot of small trout however nothing big enough you’d want to keep. Lots of rocks make it easy to snag your line. Wonderful scenery, mountain sounds and a nice walk around the lake. The wild flowers were poppin.

I might not have described this as easy. Lots of rocks and up hill.
Don't stick the parking notice to windshield, just lay it there. The glue gets baked on the glass and is a bit of a mess.
Awesome views and is very scenic. Certainly worth the effort.

Breathtaking! Totally worth the hike!

Beautiful day for this hike. Busy trail but that is good since there are no trail markers once you lead the trail head. Difficult walking with all the rocks but worth the trouble once you reach the glacier basin. Views are wonderful!

We loved this hike but was harder than we anticipated and is NOT good for all skill levels. If you anticipate hiking up the glacier and beyond, bring trekking poles, it gets a bit dangerous. (I'm sure this changes as the glacier melts throughout the summer)

We started off by parking in a private parking area (bring $5 cash) and hiking through trails that lead you through private property. We arrived at 8:00am and the lots were empty. The hike was a solid incline .5 miles to the lake. The Lake was absolutely beautiful with the glacier in the background, thick brush around the north edge of the water and trees. From the lake, the hike to the top of the glacier was a bit more strenuous. The 60mph winds didn't help as they were pushing us around. Walking on the glacier was a bit easier than trying to navigate the skeet and sliding pebbles and rocks. (a bit more dangerous for smaller children.) We had a blast sledding down on our coats. If you make this trip, be sure to throw a trash bag into your pack so you can slide down the glacier for a little refreshing fun! We were glad we went early as the lots filled up and the trail/glacier was crawling with people by the time we left at 10:45.

Spectacular! Absolutely love this place! Relatively short hike... a little steep and rocks on the trail, but not far. Beautiful views. Can swim in the lake or jump from the cliffs into the water. So glad someone suggested bringing trash bags so the kids can slide on the glacier! Bring $5 cash for parking. The only frustration were the amount of dogs off leash, on the trail, at the lake, and at the glacier. Several dogs ran up to us, and my dog isn’t dog friendly.

Love love love. Very beautiful views. Overall an easy trail but a strenuous workout. We missed the trail turn off and hiked the wrong trail for a bit but circled back around and made our way to rewarding views

Nice easy trail that leads to a beautiful lake that you can walk almost entirely around. Trail itself is entirely rock hiking but very short (we reached the lake in less than half an hour). Lots of pups swimming around in the lake and people are allowed to swim too (but beware— it’s ice cold this time of year!) There’s a nice cliff jumping spot on the opposite side of the lake by the mountain. Keep in mind that there is a fee to park in the lot $5 and it’s cash only (there are signs up everywhere that say cars that haven’t paid the fee will be towed at owners expense), so bring cash! Four stars because of how crowded the hike was.

I just moved to Colorado from Florida so we went with this did an easy trail and loved it! We had to stop for a quick water break two or three times up (it’s going to take s but to get used to the difference in altitude) but it was relatively short with a really good payoff. The mountain views, the lake and the glacier made a beautiful landscape.

nice trail, easy walk up, nice views, nice to see what is left of the glacier

Hiked this trail with my 2 year old in a backpack, and my 5 year old. My parents also came. Easier trail with a gorgeous view at the climax. Would recommend to anyone wanting to get a piece of Colorado beauty.

Fun hike with a great area to explore at the top. Glacier can be fast so make sure the kids know how to stop or stay off.

Pretty cool spot, but very very crowded. Unfortunately, lots of trash around the lake.

Completed on Thurs 6/28. Arrived at 9:00am with only a few cars in the car park, but on the way back approx. 2 hours later, it was just about full and people were beginning to park on private lots for $10 (vs. $5 in the public lot). We followed a trail around the south side of the lake up a fairly steep incline, to the top of the glacier and then looped around by crossing/sliding down the glacier. At the top of the glacier there were great views of the lake and Fox mountain. For someone not used to altitude (from St. Louis, MO), my group and I could certainly feel it - but it didn't stop us enjoying the hike. Would certainly recommend and look forward to doing it again.

Our 6 boys LOVED this and want to make it an annual event on July 4th. The short hike to the water was rocky but not horrible. Our favorite part was sliding down the glacier. Thank you to the previous reviewer who mentioned bringing trash bags to slide on. My 5 year old went on my lap and we had a blast!
Very beautiful scenery!

Great view. Lots of dogs off leash though
