Perfect weather for this hike!! I enjoyed so much by the creek, it is always nice to get a nice breeze by the water. This ended up 8.4 mile hike, enjoyed it so much! 80% is shade, so great for hot summer hike as well. Totally different scenery from hikes around Baseline. Recommended! However this is not "Hard". Should be listed as "Moderate".

Enjoyable, short, and a good exercise. Close to the road in Gregory canyon, but pretty scenery.

Nice trail but dog are only allowed on half the loop so at the half way mark we had to turn around. There were signs everywhere saying dogs prohibited on the second half of the loop. It was a nice hike with great views. We got a little lost because some it is not marked well but we figured out where we were pretty quickly since I had the All Trails app open.

The road was mainly a dirt road, there wasn’t a lot that was very moderate about it at all except when you turn off the main path and go exploring on the side paths. The views were alright, but I will say there were some slightly challenging obstacles along some of the side trails. There is one in particular that is a dead end and you can see a weather station set up at the top. Pretty cool!

Not too difficult. Finished in under four hours while carrying my 4-month old to the peak and back. Beautiful views at the top! Fun trail!

Great hike. Rated as hard because of the rocky terrain and some mild scaling of rocks but well worth the view. Make sure to pack water as the incline is pretty steep.

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.

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.

Very nice!

Really a walk, not a hike. Bob stroller friendly.

Decent trail. A lot of rocks so it felt like I was really in the Rocky Mountains! Just kidding, be sure to wear good shoes as you might catch yourself tripping on the rocks, overall easy to moderate hike. Can still hear the cars/traffic from the city.

As others have mentioned it is about 8-9 mile loop, great scenery, going counter clockwise would of been easier, didn't know my clockwise to counter and went the hard way, the wildlife is great saw many deers, snake, chipmunk, and rabbits. Fun but challenging hike, especially the last mile, which felt like 3. :)

Nice hike, great views at the top!!

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, 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.

"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.

Ended up here randomly after the line at Mitchel Lake was at least 30 deep and not moving to pay $10 to be crowded on that trail...

This was the first trail parking lot on the road to Rainbow lakes so I stopped around 2pm. This is a heavily forested hike that snakes upwards through several different layers of trees. I made it just past the 3.9 mark on the map before i turned around at 5pm. This was not a "Hard" hike by any means unless they were speaking of the length of the trail itself. This was the 23rd hike i did this season and I found this to be more "moderate." There were very few actual views through the trees and there is a site with ruins of some sort up by the environmental testing site. Lots of wood piles and old rusted metal cans and glass.

Minimal activity along trail. Secluded most of the hike.

Again seeing people just leave their bags of dog crap right along side the trail multiple times. Does someone come and pick this s-it up because it didn't seem like it. Why do people leave trash on the trail? Leave no trace? Disrespectful. Don't bring a dog if you can't clean up after your mess.

Was a good endurance hike. Would have gone further if i had started earlier. Gave it 3 stars because of the limited views and dog waste.

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.

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.

Incredible trail with great views. Took a little over 7 hours but wasn’t really hurrying to get through the trail. Would definitely do again. Be sure to bring enough water.

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.

loved this trail. lake and mountain views all around.

I started up the Sanitas Valley Loop first. Beautiful views of urban Boulder and a smattering of homes in the hills. The moderate valley trail gives way to some steep inclines as it connects with the East Ridge trail. I was visiting from Atlanta so I had to catch my breath and steady my footing as the trail ascended. Had to get used to the change in altitude. Plan to take your time navigating the rocky, sometimes not well marked East Ridge trail if your new to it and out there alone. I got out early in the am and had a few hikers help me find the trail but I can see that this trail gets very well populated after mid morning. At the top of Ridge Trail I met some nice folks who directed me to Lion’s Lair trail just beyond the summit for a good trail run. This trail was pretty smooth and the decline makes for a steady tempo run. Don’t get too comfortable because the switchbacks will keep you on your game. Overall a fun trail to test your trail speed. The locals pointed directed me on how to go from the Lion’s Lair trail to a narrow barely there trail that runs parallel to Sunshine Canyon Dr. This trail led to me the Centennial Trailhead parking lot. Overall awesome experience for a trail runner who wants to mix it up with a hike and run.
