A beautiful hike to a lake on a high bench above timberline. The lake is often ice-bound until the end of June. The trailhead is at an old smelter site. The trail climbs steeply at first into a hanging valley, then climbs gradually up the valley to finish with a final short, but steep climb onto the shelf where the lake sits.

This is one of my favorite hikes in Colorado!!! It is rarely busy and offers a wide range of environments to trek through from forest, to boulder fields to tundra. In July the fields above tree line are covered in a wide variety of wild flowers, and there are giant patches of columbines.

The climb begins quickly. You'll accumulate a big chunck of elevation gain through the first 2 miles. The trail leads to an incredible view down the valley from a pretty exposed overlook. The next couple of miles are a more gradual uphill. It is a beautiful hike through boulder fields and forest with the sound of the stream ever present. The last third of the trip is the most grueling. It is a sustained climb to the lake.

In past years I have camped along the trail then tackled Square Top the next day.

Things to note - County Road 1038 is not well taken care of and has boulders that you will have to get over or around. There is almost always standing water a few inches thick somewhere on the road. I have seen a Prius make it to the trail head, but have been on trips where the driver of a Subaru didn't feel comfortable and parked two miles from the trial head. Be aware before you try and get there and don't be afraid to park before the road becomes brutal.

Also, the trail head isn't extremely well marked when you are heading up the road. I needed my GPS to make sure I was headed the right direction and find the trail. But, there is a very large boulder with a sign that guides you, it is just easier to see if you are looking back down the road toward the entrance from Geneva Road.

Bring bug spray or permethrin clothing. This trail is along a creek and bugs become unbearable without it. You may also want to make sure your hiking boots or shoes are waterproof. The trail has standing water sporadically and there aren't ways around the soupy parts. Lastly, once you get above tree line 7-foot-tall shrubs are grown right up along the trail and can feel like they are attacking you. Long sleeves offer a fair bit of protection.

So beautiful. When you think your not going to get there, that is when you are so close. Was a little erie as we spent 7 hours on this trail and did not see one human. Mountain playground all to ourselves. Went in middle of September when all the colors were beautiful below tree line. Lake see through blue, chilly but worth it.

Great hike, but as others have stated there are a couple places that are no joke. Beautiful views with a lot of wild flowers still in bloom.

the original trailhead for this trail (634) is closed. A larger parking at the TH for trail 600 is now where you park for shelf lake. Apparently there is a connector trail from the parking lot to shelf lake trail 634. Again, I'm posting this cuz I couldn't find the TH until the afternoon and too late to hike.

Hiked this yesterday with our dog. Very beautiful trail with some creek crossings to stop and water the dog and cool down. We live here and hike quite a bit and it was a DIFFICULT hike. Steep grades the majority of the way and cairn route finding the entire way above tree line made the way up a slog. Once we passed the false summit, traversing to the lake was beautiful with wildflowers and snow. 1.2 miles after reaching the "top" AKA the false summit. Lake is nice but nothing spectacular. There was a little snow, which was fun. Again, steep loose trail had the legs burning on the way down. Only saw 1 other group on the trail. The camping nearby was also a plus, but some spots are much, much better than others. Overall a fun but difficult hike with a lake and hiking above tree line.

The wildflowers we're stunning. Literally tens of thousands of wildflowers!

Don't pick this hike unless you have a high clearance vehicle. The road is about 3 miles, covered in rocks and many steep dips.

As for the hike, it is a great moderate hike. Forests, wildflowers, views, and the lake is beautiful as you can see from all the pictures.

Beautiful and just the right amount of challenging.

Hiked yesterday. This has been one of the prettier hikes I have done recently. I would highly suggest it and do it before the wild flowers are gone! The initial mile can be quiet challenging as it is pretty much uphill with lots of rocks and steep grade. If you're not used to Altitude / steep grades take it slow. Do not get discouraged by this, make it to the valley you will not be disappointed!! Numerous wild flower fields, that lead to one more steep incline. Once you arrive at the lake enjoy the solitude and beauty. While out yesterday only came across 5 parties (all going down the trail). The FSR you take the trailhead can be a bit rough, make sure if you have decent clearance!

The wildflowers were beautiful and amazing! I loved the trail, but it was a difficult one for an older flatlander. There is a new trailhead that makes this a 7.8 mile roundtrip hike. You can still get to the old smelter site trailhead, but the signs make it sound like there is no trail access, so we used the new one.

I love this hike. I do it once or twice a year. This was my first time in 2017 and I hiked it Saturday July 1.

Was on the trail by 730 am and didn't see a single person until coming down from the summit. I made it to the lake in 2 hours flat, but could've done it in shorter time if the snow drifts had been melted. You have to scramble around them/up them the best you can to find the trail. It's still very wet, make sure you have water proof hiking boots or your feet will get soaked from some of the run off.

Once the snow drifts melt, this hike will be wonderful.

Harder elevation gain in the beginning, levels out through most of it, then elevation gain at the end signifies you are close to the lake. Enjoy!

Amazing trail and plenty of dispersed camping near by. The trail head is not a traditional trail head but Google maps brings you there. the trail marker is before you cross the stream when driving there.

Is there a place to park at the head? Do I need to go to the ranger station first or can I just go? ( first timer, duh)

Trail head is a bit hard to find. If you use google maps, it will take you to the exact spot, however there is only one tiny sign that's easy to miss. It's located next to a pile of black rocks. We made it about 2.5 miles in, but lost the trail due to snow. Gorgeous area! I would recommend stopping in the valley and turning around at the river until the snow clears up; about 2 miles in.

Really beautiful, but with the new snowfall it's nearly impossible to complete without snowshoes or even some prior knowledge to the trail. We loved it for what it was today: a 1.5 mile walk in the snowy woods.

Cuts, small but fun

Nice trail that can be a bit challenging in places. The switchbacks at the beginning can be a bit tedious, but worth it once you clear them. Trail can be difficult to see with the leafs on the ground. For the 4X4 fans. the road leading to the trail head and beyond is fun.

Tips to find the trailhead -- its easy to miss! Our car clocked 2,9 miles from the entrance sign at Geneva Park Campground, but there isn't a recognizable parking area and the small sign is on the right in the trees facing away from you as you go up the dirt road. We went passed it and didn't see the sign until we were driving back down (on the left as you go down). We'll be back to hike it - it ended up starting to snow so hard we decided to save it for a better day.
