Great hike with beautiful views, clean air, and the lake at the end is beautiful!

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.

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.

Got to the lake right at daybreak and sat there listening to the ice melt under the surface. Was an awesome experience!

Great time with my new pup Misha, she did really well for her first time in the mountains!

Did this hike at the end of June with no research on the trail whatsoever. We were simply exploring and happened to find a trail. We hiked all the way to Lake Isabelle before turning around (started late in the day). The trail is very well maintained. There was some snow around the 10,000 foot mark, and some rock scrambling near the end. On our way up we saw a waterfall coming out from a mound of snow and ice high up. We didn't realize until we got to the lake that it seemed to be coming from the lake. The lake itself is serene and beautiful. We were the only ones there. Hike was fairly easy and we would love to do it again maye this time going a little bit further.

Road is closed!

Beautiful versatile trail. Took the left off to sleepy lion at the start, great elevation gain to look over the reservoir.
Came down to the reservoir and sat near the water for lunch.
One of my favorite hikes, was crowded but not terribly so.

The road to the trailhead is currently closed for construction. I would not recommend until it reopens as it will add miles of pavement hiking.

This was a lovely hike on a sunny, brisk day. I normally don't enjoy hiking up roads, but there was a lot to see in the first 3/4 mile - climbers, dam, creek...The turnoff on the single track trail was lovely and different rock out croppings provided awesome views of the reservoir. Easy afternoon hike. For more details and photos. https://etbtravelphotography.com/2018/03/19/road-trip-to-the-rockies-button-rock-preserve/

Hiked early in the morning. Decided to go out and back on Sleepy Lion trail instead of taking the loop back which would have just followed the road. We also took Professor's Ranch trail which takes you to the top of the Dam instead of going to the bottom where the water outflow is. You will see the sign as you wind down near the Dam. Great hike with views of Long's Peak and the Res.

Hiked with family of 4. Great loop and views.

If you can end up at the reservoir around dusk this hike is magic.

This was an excellent hike. Took my 15 year old along, and she really got into the views. Most of the hike was only borderline "moderate", but as you approach the top there are a few sections that approach vertical. Made for a terrific day hike, and gave my boyfriend the urge to do a lot more of that.

Gorgeous winter hike. Tough with the extra mileage due to the road closure. Definitely bring snow shoes.

Fun trail. Felt like it should be rated a little more closely to easy than moderate, but the ice today (3/4) made it a little more challenging on the non groomed road parts. a great hike to take friends who might be from out of state (flatlanders) without overexerting them but showing them the beautiful side of Colorado.

Great scenery! Creek, dam, and mountain views. About 1-2" of snow covered the trail on our hike today. Some areas of ice and snow slush. I used spikes but my wife and friend did not. Very doable even at this time year. Will def be back during the warmer season.

Great hike with amazing views of the twin peaks. The sleepy lion trail is actually off leash dog friendly! the dogs had a wonderful time romping around in the mountains. quick hike with amazing views. will definitely do more often

My daughter and I loved this trail, it was well kept, beautiful scenery and somewhat of a challenge for us since we don't hike often. We will be back soon!

Good, fairly easy hike. Some pretty views, but the 1st half of the hike is along a dirt road.

Really I want to give this hike a 3.5. The views are great and it’s a manageable hike for all levels BUT you are on a dirt road for good portion of the hike which is not really my jam.

Great hike for the Family and dog. And the Dogs can be off the leash for a bit.!!

Wind was killer today. Trail was in great shape. A couple of icy patches in the shade otherwise all dry.
