Went on a Monday at 7am, there pretty much wasn’t anybody else out :) Nice and shady for half, and lots of wildflowers.

Didn’t make it all the way because a lightening storm came creeping in on us really early and had to book for the trees down below. But overall such a pretty trail. It’s quite muddy down below in the trees with lots of mosquitos and then a short snow crossing above tree line. The views on RMNP is INSANE

STOP BROWSING TRAILS AND GO HIKE THIS NOW. When I say stunning vistas that should be illegal they're so breathtaking, I'm not joking with you. Loch Vale transports you into this other universe, and the views you have off the ledge from Lake of Glass are incredibly humbling. There is snow towards the top, but it's so packed down that the trail is clearly marked. I hiked it fine with trail runners and shorts. Listen though, so there's this waterfall you have to vertically climb up right before Lake of Glass which is immediately before Sky Pond, and that was FUN! It made the hike technically challenging and different from a lot of other hikes in the area. Okay now that were so far down, the secret to finding parking is: don't go at 6am. I went at 1230pm today, a Monday in July, and although there was ample signage saying Bear Lake parking was full, guess what, it wasn't. There were plenty of spots open. Also, I mostly saw people coming down the trail, and after the first half there were only a handfull of other hikers. Let's keep these crazy morning hikers full of frenzy though so us afternoon explorers can have our peace and quiet on the trail ;). Just bring a poncho and you'll be fine if the 3pm sprinkles hit. Go werq!

Awesome trail! There are only a couple of spots that require 4WD. The views are amazing.

Great views from the top part of the hike. A few fallen trees across trail. Had to go off trail many times to navigate around areas of snow, but well worth the effort.

This was a fun hike! It deserves the “hard” rating because it’s got a steep switchback section that makes you work. The waterfall was beautiful. I was able to cross the creek and go to the bunkhouse (very cool to walk through) and the mine building and shaft. The section from the bunkhouse to the mine building is fairly exposed...so be careful if you have kids or dogs. The view of Ouray is best from the mine shaft. You gotta go all the way to get that outstanding view of the mountains and the city. It’s unbelievable!

Gorgeous hike with stunning vistas. Rather than waking up before the sun I just went in the afternoon on Monday and there was plenty of parking. Also, there were only a handfull of people on the trail.

In my humble opinion, this is one of the hardest “moderate” trails I’ve hiked. Took the entire family and had to carry one of my kids the final .5 miles down. Not complaining though. At the top you can enjoy feeding chipmunks that will come right to you for food. If you are out of shape or have poor physical condition I would definitely avoid this trail. Otherwise it’s great!!!

thank you Daniel Kane! great directions! awesome hike!

this was a beautiful trail. Not very heavily trafficked. Parts of the trail still had snow and some fallen trees. There were patches of mud and little rivers. plenty of spots to get water. right after the cabin the trail was starting to become really steep. it was all worth it.

Great hike! Glad I had bug spray with me. Almost forgot sunscreen and a hat. I’d say these three things are all essentials

This is a great little family hike. We went up the ski hill side of the loop, in the direction of the houses, which meant that we got to save the best part of the hike for the end. On the way back down, the trail follows a shaded creek that provides an intense sensory experience - rich forest fragrance and the constant chatter of a rushing creek that was as clear and clean as any I have ever seen.

This trail was definitely hard but worth it. Not very many people after the turn off for Mt. Yale. once you get to the lake there were quite a few trees downed from the avalanche. volunteers had come in and cut away some of the trees. the bugs were out but not swarming quite yet.

Nice paved path, lots of bikes, periodic shade. Stone house with a lovely garden.

This was a challenging but fun hike for many in our group. We spanned from 3 years old to 75 years old and everyone made it to the falls and back. The footing is pretty tricky for about a third of the hike, but the payoff for a long trip to the falls was a breathtakingly beautiful vista.

Had just exited I-70 at Cameo and pulled into the area when we met a car coming from the other direction. I stopped him and asked, “did you see the horses?” He was from the New England area and responded with “na, we didn’t go dat faa.” Then his wife added, “its all wiiildness our thee.” I’m thinking, “Awesome, it’s 92°, we came all this way and aren’t going to see the wild horses.” About a .5 mile in the first horse peeks his head out from the east in washed wadi. 3 horses in total. We get about 20 feet from a horse until we return to the trail. we go off trail about 500 yards and get even closer to them. The first hill is steep, until the fence with a gate you can easily bypass. If it wasn’t 92° we would have followed the 3 horses for as long as we could keep up. Parking is 1.7 miles after you cross the bridge over the Colorado River. It has a unisex outhouse and parking for 40 vehicles. There is a shooting range eithe side of the trail until the parking area. Go See the horses, maybe you’ll get lucky! We did! We went at 5:30 pm and were with 3 wild horses within 20 minutes!

Started up the trail at around 615am, later than we’d planned. The weather held up, as we made quick enough time (even with multiple breaks) and were off the mountain by 1130am. With a fairly strenuous first part of the hike, we warmed up quickly and stayed that way the rest of the hike. The return trek to the trailhead isn’t a simple downhill - there are several uphill sections both on the way up and back. As others mention, the views are second to none!

Great hike, not difficult. Plenty of different zones of nature, very beautiful views. Definitely recommend this trail.

Definitely a beautiful place. Will say there is no shade so don’t go on a really hot day. And do not bring your dogs. There is signs everywhere saying NO DOGS and for some reason people think that rule doesn’t apply to them.

Well worth the effort to summit Lookout Mountain! Beautiful 360-degree views of both Thompson and Poudre canyons and very little traffic. There is a meadow about 2 miles into the trail from the Miller Fork trailhead that has been a bit difficult to find your way out of. We marked the trail out with a cairn and green survey tape. When you approach the “saddle” up the Lookout Trail at Donner Pass, the trail from there disappears and you have to bushwhack to the top from there about 500 feet. A few cairns are placed there to mark the way, but mainly it’s pick your own way.

We hiked it today 7/15 - it is definitely still damp up there so there were mosquitos and a bit of mud. I would recommended bug spray if you are hiking this trail in the next week or so. The trail is pretty moderate - quite easy for the first 2 miles and then more of a climb for the last mile up. The lake is really pretty! I would do it again when the bugs are gone. The highlight was the moose we spotted on the way down.
