Quite the incline for about half way, but worth the view once you hit the overlook point! Going back down is a breeze!

This was a great hike. Fair amount of people, yet not crowded. Still peaceful and fun. Dog-friendly, with friendliest trial I’ve ever been on. Steep hike up, rocky and often narrow, little protection from the cliff, but worth it. Take it easy, rest. It’s a great afternoon. View of Crag’s Hotel and Continental Divide is spectacular. Oh, and stop in the river once you’ve come down.

8 dollar parking.

Normally I'm ok with the poplar trails but this one is getting to be a joke. the lake is beautiful, great place to eat; until you get a mom and her children coming up while you're eating and proceed to strip And skinny dip right in front of us, not only was this incredibly uncomfortable for us who were sitting there first but girls proceeded to PEE right in the water!! squatting right in front of us eating our f*cking lunch!
I'm all for skinny dipping but have some respect for the people around you, please don't expose your 10 year old children to the entire lake and DO NOT pee in the water!

This is a pretty nice trail. Nothing spectacular, but it’s a good time.

very quick and easy trail with an great lake at the top. do this and diamond lake in the same day if you have time - the Lost Lake trailhead starts where the road splits to lead to Diamond Lake. get there early bc it gets very busy and hard to park.

Did this hike on a Thursday morning. Parking was tight but found a spot around 1130. Started the hike, took a detour to the left and found some beautiful waterfalls. Had to backtrack to get to the main trail. Rocky in parts. A bit of an incline at the end, but worth the view at the lake at the end. Not as narrow on the trail as other hikes. Quite a few bugs along the way but none at the lake which was a great place to grab a bite and enjoy the view.

Great hike. Offers a challenge but not too steep - it was fairly easy taking it slow. The trail has plenty of coverage and great views! Fairly busy but we were able to avoid most traffic by getting there in the morning. The loop is less busy than the main out & back trail. $8 to enter El Dorado park.

This hike is great for a very easy hike with some awesome views. If you enter from Eldorado Springs you'll have to pay $8 to park your car, but you really see where that money goes while walk the well manicured trail with retaining walls on the side. If you park at the other end of the trail it's free (considered Boulder Open Space). The first half of the hike is very scenic, while the rest is pretty open and not as many views. I would suggest branching off to Spring Brook North Trail or Rattlesnake Gultch.

Walk the path by the river, it’s beautiful and is not nearly as rocky. We walked the river path up and it was gorgeous!! It brings you out at a nice place to lay out in the rocks and then you continue on to the main tail to the lake.

Busy trail, lots of dogs, but great views

The trail is beautiful and not too difficult. But I have to agree with other commenters that it’s very busy on weekends and the amount of loose rock is tricky. I still recommend it though because the lake and the waterfalls are relaxing. Also, parking at the Nederland park n ride and getting the shuttle is the way to go; it’s there every 15 minutes on the weekends and you don’t have to deal with the scarce parking at the trail head.

beautiful setting, steep uphill climb. had a 7 and 10 year old on the hike, we had to stop many times as it's a long uphill climb. overall we really enjoyed the hike and views.

Nice well marked trail that takes you up to Lost Lake, a clear, shallow mountain lake at about 10,000 feet elevation. It’s a bit tough on the way up, but a fun hike down. Nice Mountain View’s and shallow rocky rivers with a couple large waterfalls.

Fairly easy hike. Good trail improvements along the way. Definitely a lot of wildflowers, waterfalls, and scenery. The lake at the top is worth every step. We would definitely come back for a picnic lunch on a nicer day. The clouds started rolling in once we made it to the lake and we had to cut the chill time short. I definitely recommend blazing your own trail at the bottom to see a few waterfalls that aren't as easy to get to or see from the main trail. As other reviews have stated stay to the left.

This is a fun trail to go on with kids. No climbing involved and is very easy relaxed hike. We found wild garlic growing and this trail is awesome if you start at the North Boulder Recreation Center and circle all the way back. There are places to dip your toes in the water but we need to come when the sun is up otherwise it can get cold

I love this hike, great views, like waterfalls and rolling rivers. go early or go late

Great hike! A bit rocky throughout. We had a little trouble knowing where to go to go around the lake. It was busy and parking was tight. Would go again!

Nice trail to hike with oldest son and grandson!

Great hike, perfect length, great views and a variety. Storm rolled in at the top and while I was at the divide overlook, made the mistake of heading back instead of waiting it out - cleared back up in like ten minutes. Followed it up with the first little bit of Fowler. Decent amount of people (~11am on a Sunday) but I wouldn’t say it deterred too much

Nice mix of history, railroad and views

I’ve hiked this trail today and it’s a very beautiful trail. It doesn’t follow the red rock trail for most of the hike, it turns onto a black trail. But it’s absolutely worth it. You can also choose to continue following the red rocks trail, it’s an easier trail with less ascending. However if you are in a decent shape, take the black trail via the top of the mountain for beautiful views of the city. Watch out for rattle snakes, I’ve seen one sunbathing on the trail. More people have seen them a lot sunbathing.

Very pretty. Easy hike. Would be very enjoyable with a bike. Lots of pretty flowers. Bring bug spray. Lots of mosquitos and biting bugs. I was not prepared.

Not very good for bikes was very rocky with sharp pointy Rock sticking out. It was only my fifth trail on a mountain bike so I'm just a beginner.

Fairly busy trail but great views and not too difficult. Mostly shaded.

great trail! it took us about and hour and 40 minutes from start to finish. pretty heavily trafficked especially for a Wednesday

Great hike. Beautiful views and waterfalls. Trail is stupid busy. Do yourself a favor and park in Ned at the Park n Ride and the the shuttle or you're going Yo end up adding an extra mile or two to the hike. Would be 5 stars except for the parking.

This hike took us 1.5 hours - we didn’t stop other than to walk around the hotel ruins and we decided to go up and to the left before we got to the continental divide overlook. There is a little unmarked trail to the left that goes up to a large rock - you can climb on top and the views are amazing. It’s dangerous as there is a steep cliff, dropping straight down. Great weekend morning hike!
