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!

Hit the trail at about 7am on a Saturday and it was great, not crowded but started to see more people in the way down, still not bad. Definitely strenuous, but I haven’t done many hikes lately so I’m not sure I’m the best judge. Pretty mellow first half until you climb between bear peak and south boulder peak, easy to hit both while you’re up there and each offers a little bit of a different view so definitely check both out (only adds like 20 minutes I’d say to the hike). Very pretty views and diverse vegetation from top to bottom which kept it interesting. My knees were shakin’ on the way down as there’s lots of rocks to go down but that’s only about 1/2 of the trail, as the first half is quite wide and gravelly. Would definitely do it again!

I really enjoy this trail. It’s easy, breezy and sleazy.

great short family hike

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.

Very nice!

Nice hike, great views at the top!!

Attempted this hike today and saw 2 Rattlesnakes on the trail within the first .5 miles. I was alone and decided not to risk it but will re-attempt in cooler temps with a buddy. Trail looks very nice but minimal shade.

Well maintained trails that are surprisingly pretty busy. Definitely take some water with you and wear the right shoes, rocks can get a bit rough at some parts. Plenty of hills and the views are gorgeous but if you’re not used to the elevation, I’d recommend taking it slow at first. Only down side is it’s a state park so you have to pay to enter.

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.

Loved the hike there. Got to the trailhead at 5:45 PM for a sunset hike and finished the hike at 8:20.. about 2.5 hours of hiking and gaping at how beautiful Golden/Colorado is at the golden hour and at sundown.. the trailhead is wayyyy less trafficked at the time we went. Had my dog on a leash all the time because of the rattlesnakes but seemed to be ok!

This hike starts with a gradual incline for about 1.5 miles through the spruce and fir forest. Once you break out of the trees at timberline, the rest of this hike (4 miles or so) is exposed high tundra hiking. IF YOU HAVE ARE BRINGING A DOG...there is no water at all on this trail. Just FYI. After treeline you get your first big views of north Arapahoe peak and Apache peak. You are also able to see the lakes down on your right associates with the Boulder watershed. The hike begins to climb from this point up the tundra with a few different switchback sections. You then end up on the south side of the ridge where you have great views of eldora ski area, Mt Evans, and all the mountains on the continental divide looking towards winter park. We could also see Grays and Torrey’s, and Bierstadt, and Pikes peak way off in the southern distance. You head along the ridge here for a couple miles at a pretty even grade until you meet up with 4th of July trail. At this point you can see the peak to your right which is the way to south arapahoe peak. This is why the trail has a hard rating in my opinion. It’s a steep rock scramble up to the top but well worth it.

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.

Great hike, nice views. Lots of sun, only a few areas that were shaded, so don’t forget a hat and some sunscreen.

Definitely a challenging trail. I’m in good shape but being from a lower elevation, I felt pretty winded at times. With breaks I still took about 4 hours with a half hour break at the peak. The view was worth it for sure. Highly recommend getting an early start since the trail is in the full sun at the beginning.

This hike borders on moderate to hard. A fairly mild incline with a few steeper sections. We have run into a large bear on this trail so be alert and be prepared for what to do. We had to turn around the last time when the big guy would not back off and grant us passage.

Easy trail with amazing views of the Flatirons.

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.

The cows made my day! Nice views otherwise.

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.

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

Great hike, go during a week day in the afternoon if you can there is way less traffic. No mountain biking on the trail so that’s a plus.

We did about 5 miles out and back of this trail and it was a really beautiful hike, nicely forested and at least the first part wasn't too strenuous. Not many other people on the way out as we went early enough. I definitely hope to go back to do a more extended version of the hike.

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!

Good hike. Beautiful views. A little much for my 9 and 11 year old.

It was so beautiful!! Near the end we saw the cows drinking from a pond close to the trail. It’s free for people who live in Boulder. If you don’t, you’ll have to pay a $5 fee. Just make sure you bring some cash. I didn’t but luckily my friend did.
