Users have reported that there is only one dog per person allowed on this route. A great rocky trail with a few steep sections. Well shaded in the morning. Dramatic views of Long's Peak, Mt. Meeker, and Twin Sisters beyond the reservoir.

Really busy but people were pretty spread out arrive early if you wanna guaranteed spot they were turning some people away from the lot when I got back down

Really pretty hike! Got to the parking lot around 850 and there were plenty of spots and the Trail was pretty empty as well. The reservoir and dam are beautiful as well

Started at about 5:30 pm and only saw four other hikers on the trail. Great workout and beautiful views.

Start at the point when the dirt road turns off to button rock dam/sleepy lion pass. Starting around the dam to only button rock dam made it difficult to see the sign of where to turn around to loop back. The sign faces your left and back and we never looked left or back and got to the top where it turns into a lumbar yard. Realizing that something was wrong we went back a mile and saw the sign because it was facing us at this point!

Always love doing the full loop. Veered off the dirt road to enjoy the scenic route. Got there around 5 and crowds were just leaving, not too many people on the trail itself. Weather was beautiful, not too many bugs, and got to even watch some beavers on the walk back to the car.

More like a walk than a hike but still beautiful! Will definitely come back!

Quite a bit of loose rocks on the trail that can be pretty sketchy on steep parts. While there were some great views along the way, much of this trail is a dirt road that runs to the dam. Once you leave the dirt road, the incline is pretty steep for most of the way to the peak.

Beautiful! It was nice trail to do during Covid-19 because the trail was wide. I was able to maintain a solid distance from people the entire hike.

This trail was really pretty with a few steep parts in the beginning. Although a lot of the trail is a dirt road with no shade. Definitely worth the view of the dam and a pretty walk along the river!

Beautiful hike! We did the Sleepy Lion trail. A bit technical once we hit the trailhead for about the first half of the loop (4 miles on trail, 1 mile to trailhead and back) but all dry!! So nice to get out in nature. Perfect weather, mostly overcast though there was plenty of tree coverage in the trail. Arrived around 1pm today (Weds) Found parking right away. Not crowded on the trails at all. Would definitely recommend.

Loved the Sleepy Lion hike! Went up at 1 pm on a Saturday afternoon and was able to find parking in the lot closet to the trailhead. Pretty heavy incline on the beginning of the hike but worth it for the views. Keep an eye out for the cactus with pink flowers and other wild flowers growing right now! Also note the public restrooms are closed at the moment.

Nice trail well kept! Most of it is an access road but you can turn off to a nice trail off the road which is the sleepy lion trail! Get there early parking at trail head was full when we got there at 9, having to park further, 0.8 miles from trail head!

Gorgeous trail and not too much scrambling. I recommend following the arrows that AllTrails provides for the direction you complete the hike so that you start with the incline and finish on the flat road. Very minimal parking at the trailhead, so plan to park up the road. It started getting more crowded around lunchtime but otherwise wasn't too bad.

Trails in great condition. Walked up the main road to the dam, enjoyed the peace and quiet of the reservoir and then came back down the sleepy lion trail and enjoyed the incredible views.

Gorgeous trail! Does have some incline and rocky parts on the trail. Totally worth it for the views. Great day trip. Lots of wildflowers.

Awesome trail!

Decent little hike along rushing waters. Nice wildflowers this time of year. If you go clockwise around the loop it’s a bit more of a scramble up. If you want to fish, you need a Longmont permit in addition to the state license. Limited parking.
