The moose warning is no joke!! I had one run out right in front of me, if I hadn't been paying attention it would've mowed me down, scared the crap out of me... Be very careful on this trail! Great long day hike with lots of shade and mostly sticks along the creek. There's a waterfall that's a little more than halfway, but overall the views are mostly cut off due to the dense tree coverage. Ended up doing the extra mile to Brainard lake and wasn't disappointed. Saw a few bikers and hikers but the trail is pretty empty.

This was a nice quick hike! We brought along our doggo and there were many shaded areas to stop and rehydrate.

Went to the rocks for the first time today and it was a great hike. I just moved to the area so I’m still not quite use to the elevation. I got winded a few times but it wasn’t hard. It’s a great view from either side of the rocks. Highly recommended!

Great hike with some difficult parts. Great views at the top. Highly recommend good hiking shoes....not tennis shoes, chacos, or sandals.

Good hike and close to Boulder. Start early - you can either do out and back (starting clockwise) or loop (starting counterclockwise). First .5 mile of counterclockwise is flat, wide, gravel. The rest of it is a lot of switchbacks and exposed, so wear sunscreen and start early.

I usually don't have to stop and I took a few breaks this time. Great workout and doesn't take too long. Start early!

Really loved this trail. It was 60 and breezy and beautiful. We went on August 19, 2018. Saw a few people but very peaceful and lovely. Loved walking next to the creek the whole way!!

Great views along the river!

Awesome little out and back close to downtown Boulder. My pup loved it! Bummed the creek was dry and reservoir is very low, might be better to do in the late spring time. Definitely worth getting there early & avoiding the rush of people!

Some hard steps in the beginning then trail. Bikers are hard core as they pass!

it says moderate, but we thought it was closer to hard. beautiful hike, though, some stunning views of the city when you first start out. from the top you can see Golden to the left, and way in the back you can see downtown Denver, so you really can see it all.
the sun would beat down during the climb up, and then In the forest it cooled down.

This is a beautiful hike for all ages. One of my favorites. We went during the week and got there early, so very low traffic. Just enough elevation towards the end to get good exercise.. However, as other reviewers commented on, the beauty was marred by the sight and smell of dog bags discarded along the trail. Dog owners, PLEASE dispose of your dog waste responsibly! It is so unfair to those of us that are there to enjoy the sights and scents of the forest, not smelly dog poop bags that have been sitting abandoned in the sun.

Good, easy hike with kids. Plenty of shade, nice views toward the end of the trail. Waterfall and creek are dried up, I am sure it is more beautiful with higher water.

Excellent trail! we did the first leg to the peak about 3 miles. mostly open until you start the climb. Climb was challenging over rocks, right turns. Peak had amazing views. Took Lion's Lair trail back down and this leg was mostly paved but a long 5 miles or so. Overall a really nice park in Boulder with several interesting trails.

Definitely some nice elevation gain with this one! I started at Gregory Canyon and ended on Flagstaff. First mile or so was all uphill and included some rock scrambling. Saw lots of wildlife including a deer. Rangview was also a lovely little hike. Ending with the Flagstaff trail, this is the part everyone speaks of that runs along the road and requires several road crossings. I didn't necessarily find the traffic bothersome but finding the trail after crossing the road could be somewhat difficult, however the alltrails map is super helpful. Would definitely do this hike again! I enjoyed the scenic views of Boulder and the challenge this hike provided.

you walk along side a lake up to another lake. a cool and easy day hike with great views.

Definitely listen to the other reviewers and drive to the lot at the start of the trailhead! Also, don’t forget to continue past the second lake up to the third! The view is so worth the climb and you’re practically all alone at the lake. Great spot to enjoy a picnic lunch.

Did this trail in midJuly with an out of towner (from sea level) who had a tough time adjusting to the altitude change. We AWD our way up to the trailhead which was very rocky but doable in our vehicle. Beautiful wildflowers. First lake is pretty, can’t get to it d/t private property, can see almost the whole trail. Second lake was a bit of the way up, more closed off but beautiful. My visitor didn’t want to try for the third lake so we turned around and headed back.

I've only hiked this trail once and it is a really cool trail, especially 12 minutes away from my house in the city, but the main drawback for me is all the bikes. It's a very popular MTB trail and I had to pause pretty much every other minute to let a bike go by. A few bikes hurtled toward me and expected me to lunge out of the way. Overall it was hard to settle into the hike itself.

I have used AllTrails for a long time, finally purchased it - just saying, why did I wait!

I did this trail today. I was impressed, given the use it gets, how clean it was. Around the trail head and at the lakes there was no trash. It gives me faith in outdoor humanity. It is a lovely hike. Good for young hikers.

Lovely day hike

I will never get tired of this drive. I do get tired of the growing crowds though. A small inconvenience to deal with while enjoying the Colorado Gold. Heads-up. Lets practice good road and trail etiquette here, especially during leaf peeping. Many thanks from a CO native.

The hike is okay. The 'castle' ruins are really neat!

Quintessential Boulder hike. Went clockwise today - I prefer to tackle the big “steps” on the ascent and come down through the valley. Always nice to have bathrooms (across the street from the trailhead.) Friendly faces and interesting terrain. A perennial favorite.

Great hike. A little crowded on weekends but worth it.

Nice, short trail for a quick nature getaway. It is quite steep if you enter from Settler’s Park, much more than expected. There are beautiful views of Boulder at the top. Bring lots of water and sunscreen as there’s not much shade.

Great views and a well maintained trail. We drive our Outback up to the trailhead parking lot no problem. Few spots where good driving was needed due to drainage ditches. Wouldn't want to take anything with lower clearance than an outback though. Started hiking at 0830 and saw only a handful of hikers. By the time we were done, the lot was full and the trail was quite a bit more populated. Totally worth the hike though!

I give this hike 3 stars in the summer and 5 stars in the winter. It's a great location, just over an hour from Denver and you get to go through Georgetown and past Idaho Springs which both have fun food/drinking options for post-hike. For summer, the hike is easy/moderate and isn't terribly exciting - ranging from 4 or 6 mi round trip depending on if you're able to take the AWD road or not. People mention wildflowers, but compared to most other hikes in CO, there were next to none. This is a lovely quick hike if you just want to get outside and move for a bit, but isn't particularly photogenic if that's what you're looking for. However, in winter it's spectacular for snowshoeing. We came on a Saturday in April and didn't see another soul til we got to the car. It's more strenuous on snowshoes, so that makes it a little more entertaining. The trees are beautiful in winter and you can't beat walking on a frozen lake.

Didn’t love the road noise. Trail was broken up and went through town. Had to cross the river to find any real trail, but then I wasn’t near the river.
