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.

Great trail for the pups. Enough shade and they enjoyed the break in the water about half way in. Clean trail, not crowded on a Friday and perfect hiking weather. We will be back!

I'm a pretty avid hiker, and this trail still kicks my butt, every time. That first section is pretty brutal. Definitely not a climb for someone who is afraid of heights (I totally am.) The meadow above the first climb is a nice surprise. After that, there's some scrambling and a sketchy spot across the coal seam that washes out some years. The views over the desert from the top are otherworldly.

One of my favorites especially in the fall. Beautiful grove of aspens toward the top.

Now one of my top five all-time favorites. First time I have done this hike. Only went to Blue Lake—didn’t do the rock scramble up to Little Blue Lake. Has a little bit of everything: river crossings, valley views, lake views, etc. I prepared for mosquitos after seeing all the reviews where people got eaten alive, but we went mid-August and some of the wet areas were dried up, so I’m thinking the breeding grounds weren’t as plentiful. We didn’t see a single mosquito. Most of the wildflowers were done, but there were still some blooming here and there. We saw a female moose and her baby lounging in a meadow. On the way back we saw a bull moose across one of the ponds. Also saw various other smaller wildlife. Nice to have facilities right at the trailhead. Went on a Thursday morning at 8 am and got in no problem, but there were plenty of cars in the parking lot.

BOTH DOGS GOT BITTEN BY RATTLESNAKES DO NOT GO IN THIS TRAIL, ALSO NOT A SPECTACULAR TRAIL SO DONT BOTHER

Beautiful hike. Get there early, it gets crowded quickly.

Amazing hike with 11 and 13 year old kids. Crowded at Alberta Falls; but the crowds really drop off after that. The Loch is GORGEOUS, but don’t stop the the edge. Walk all the way around to get the views. We saw two sets of elk swimming in the lake. Would have loved to go all the way to Timberlake Falls or Sky Pond, but my family wasn’t having it.

Great hike. If you're going to go, get there early. Parking fills up and then you have to wait to even get in the park. The path is a little rocky, but not bad and the views are awesome.

It was my first time hiking in Colorado, great place to start. Really fun and enjoyed the beautiful views. Was a bit hard for the first time but I bet if you are used to hiking it would be a pleasant hike.

Great trail! Make sure you do the sleepy lion trail up. When you hit Hull ranch do not go that way go to the right where you will find the summit of the trail and a gorgeous view of the lake. We almost missed it and went the Hull route. There’s not a lot of shade on the last 2 miles back so be prepared for that.

Nice hike, great views at the top!!

Start early!! We started the trail at about 930 but it was already super hot. Other than that it was a beautiful trail, lots of little places for shade and lots of cute little lizards.

Didn’t get up to area until 10:30am, on a Monday however no trouble parking at brainard lake parking. Beautiful lakes, meandering paths until you reach Mitchell lake then it is rocky path up to blue lake which is not difficult to navigate. Trails very well marked. Did not attempt little blue, however, it must be beautiful. I can only imagine. It must be a very steep rocky ascent. It wasn’t overly crowded however once at blue lake you certainly see and hear others. I can’t imagine it with more people. We did have a moose sighting which was a gift. This hike is now one of my must dos during my annual visit Home to Boulder

We hiked this trail on the way to Andrews Creek campsite and it was awesome. We caught some nice sized rainbow trout that we cooked up for dinner. You need a permit if you are staying overnight and the campsites are by reservation only.

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.

I do this trail every Saturday morning. It's a nice little hike through the woods, just no real payoff..

Nice trail with a variety of terrain. This trail may be considered hard for those who do not hike frequently... some narrow, rocky areas with over 1000 ft of elevation change. The river was a nice spot to stop for a rest half way through the hike.

7/8/18 7:30am and the parking lot was getting full. The drive was nice and was winding, littered with bicyclists. There was a bike race from 7-10am. $11 entrance fee. Lake Isabelle was our intended hike but due to a death the day before it was closed off. So, Blue Lake it was! 6mi round trip hike. 1mi to Mitchell Lake and 2mi to Blue Lake. The trail was easy to navigate. There were tons of people at Blue Lake hanging out and sunbathing. We encountered several groups on the way up and even more on our way back. There were also a bunch of dogs on the hike. Everyone was great and had them on leash. We ran into 2 park rangers, one of which thanked us for keeping our dogs on leash. The views throughout the hike were spectacular! Wild flowers were abundant and hearing the sound of water nearby was relaxing. All in all, this was a beautiful hike. I would recommend bug spray (tons of mosquitos), sunscreen (obvi), water, and snacks. Please be sure to pack in and pack out.

A nice workout with a strong hill qt the end. - beautiful - the river was great for my dog too :)

"Stairmaster Sanitas" is a great place to get a very real workout in. We are in decent shape and climbed up Sanitas and went back around the valley loop trail within 2.5 hours. I would categorize this as "moderate to hard" given a few of the rocks you have to scramble over and how steep it is. While you can carry a child on a backpack up an down, it's not the greatest one to choose for that since you might have to shuffle a bit over rocks, etc.

Beautiful hike on August 6, 2018.

I did it with stock new Silverado. it was brutal for this kind of car, though it has 4x4 low and all that crap, this trail is not for stock SUV like KIA sportage or so, because it is really rocky and you dont enjoy the drive.
I would recommend a jeep or something like Expedition for this.

other than that, lake is nice and all, but not breathtaking.

Great distance and elevation for beginners who want to get some incline!

Enjoyable, no one in the trail today even though it is Saturday, maybe because it was hot! Steeper climb if you go counterclockwise. Good day, will do it again when it cools off.
