It was so beautiful. My kids really enjoyed this trail!

We set out early on 05/19/2018. Parked at trailhead off road N 40 19.153. W 105 32.478. Very grey overcast day, trail a bit hard to follow at first for a couple of newbies, but made the trek with no problems. The fun was within 75 feet of the top, A bit of creative rock climbing involved, but we made the top even with inadequate footwear! Totally in the clouds today with no view but had the top to ourselves, with the exception of a couple of ground squirrels, for 40 minutes. Saw maybe a dozen hikers on the trail. Got back to vehicle just before a bit of rain.
Left with a sense of accomplishment !!!
(For most of the trek we had cell coverage unlike most of the trails in RMNP proper.)

Great hike with a variety of trails and many water features with the river, outlet from the dam, spillway and water fall. A real gem of an outing! Hike done on 5/12/18.

A beautiful and moderately challenging hike. Not the hardest in Estes, but well worth the view at the top.

One for the books. Take a good human with you for a guaranteed good time. Not many people during the weekday. Water was really nice. Good snacks a must.

Tough. But stunning once you are on the rocks.

Read the reviews - they give great directions for following the tail.

This is truly a hidden gem that has a great view at the top!

The View-
Along the first half of the trail you can spur off onto some outcroppings and get a nice view of highway 7 and the southern portion of Estes. At the top you can see for miles! Clear line of sight of Longs Peak and a full 360 view of other mountains in the area.

The Trail-
Dogs allowed on leash. No snow the entire way and it took about an hour one way. The trail isn’t very well maintained has large rocks and roots sticking out along the trail, so watch out! There’s a few times along the trail where it was hard to tell if you’re on the right path, so have a map or GPS. Towards the top you’ll need to climb over large boulders and it can be a little technical for some. There’s not a whole lot of room for big crowds at the top but the view is great!

There’s not a whole lot of parking available, it’s whatever you can find along the side of the road. If it’s packed you can find more parking downhill (north) from the trail head along the highway. During the warmer months there’s a lot of traffic along the road so be careful!

Beautiful hike! Good variety of terrain. A large portion of the loop allows dogs off leash. The trail has good shade about 1/4 of the time, On a hot day, this one might be rough - wear sunscreen.

Hiked 5/11 excellent hike! Pretty challenging, but worth it. The end involves finding your own way up through some pretty steep rocks so be prepared. No snow on the trail and dry. The view is amazing, full 360 if RMNP one of the best views I’ve had short of 14er’s

A great trail to start the season. a great view of longs peak. very dog friendly.

This is an excellent hike to take your in shape flat-land visitors. The hike is moderate with only a few slightly steep areas to get the blood pumping. This hike offers plenty of shade and rewards with lots of wildflowers and amazing views.

Very pretty hike. Well maintained trail with lots of wild flowers. Good amount of parking spots

I hiked this trail with a 48lb vest... it was fairly easy. Probably a lot easier without the extra weight.... dogs are welcome on this trail!!

Hiked yesterday. The trails had patches of snow at the top. The views were amazing. Dog enjoyed the hike.

For first time visitors: departing from Estes, if you hit Lily Lake you have gone too far. The entrance is not clearly marked but is on the west side of the highway.

I wish there was a way to remove the graffiti near the creek.

Overall, a good hike.

Great trail!! Pretty easy and dogs loved it!! Amazing views!! ❤️

Great hike, large portion of the hike allows for dogs to be off leash. Very pretty views of the lake as well. Make sure to plan extra time if you think you want to go to the lake, you have to climb up from the bottom of the dam to see the lake and its a bit of a hike!

Love this hike. Overall pretty easy with beautiful views. Plan some extra time to go to the lake and maybe take a lunch

Great trail for running.

No snow or ice. Half the trail is a dirt road but trail is very pretty and full of great views!
Do not have to pay to park.
Bathrooms at trailhead.
I’d rate this as moderate to difficult as there are some steep inclines. There’s a huge damn which is also really cool.

A favorite semi challenging trail.

Nice views on a hike pretty much anyone could do. Decent climb when you come off the fire road for a bit, eventually turns into a wide smooth path for the descent. Probably about half the hike is on wide, smooth dirt path, some of that is fire road. Good scenery and low traffic. Good amount of the trail is off leash for dogs. Tons of water features which adds a lot to the fire road parts.

Was really good minus people having their dogs off leash in non designated areas

Good view of the distant snow-strewn peaks and a reservoir. Wildflowers are starting to emerge now. Not a lot of scenery to look at unless you're at the very highest point of the trail, but besides that it was an easy trail with decent enough reward at the top. Very few people hiking on a Monday afternoon. Only passed two groups of people.

Once you get to the point on this trail where it turns into a road that heads back to the parking lot (clearly marked with a sign) and there's a building where the reservoir water flows out into a river, I'd also suggest heading up the 'Hummingbird Switchback Trail' that goes up to the Ralph Price Reservoir. It's short and you get a good view of the water, and can even follow a trail all the way around the lake if you want. From there you can take the road that goes around the reservoir a bit and also leads back to the parking lot.

Hiked yesterday. Packed snow and ice along the trail, but was able to do it in just hiking boots. Trail is pretty poorly marked so you definitely have to pay attention. Some scrambling toward the end of the trail. Views at the top are GORGEOUS!

Nice hike. Did this last September. Definitely on the easier side of Moderate. Nice and shady for most of the hike. The dam is awesome and a great place for lunch. Some nice views along the way as well.

Beautiful rugged hike. You start out the first half mile or so on a service road but it’s going along side the St Vrain creek, so the scenery is still beautiful. Also I’d say the last 1.5 miles of the loop are coming back down the service road, but again, still feels plenty secluded. We went on a Wednesday and hardly ran into anyone else and parking was not an issue. Once you take the trail (it’s on the left off the service road) it is pretty steadily inclining for a while. Gorgeous views of Longs Peak at the pinnacle. Would definitely do again!

Loved the scenery on Sleepy Lion Trail! Make sure to turn left onto the trail off the main road. I accidentally made a left turn into Hall Ranch and turned my 5 mile hike into over 10 miles, but a lovely mistake! I saw over 20 deer close-up and a huge mountain peak before returning to Sleepy Lion Trail. Also saw eagles, wildflowers, and a rabbit. Finally hit the dam and took Hummingbird Switchback Trail up to Ralph Price Reservoir. Absolutely beautiful around 430pm! Took the road back to the car and enjoyed walking by the river.

Quick morning hike with lots to look at. Trail was essentially dry on 4/7/18 which is always a plus.
