This is a really great day hike if you live nearby and are off to a late start for the day. We came from neighboring Longmont and started the hike around 3. Got back to the car right after the sun went down. The creek is beautiful and it's really cool to see some local infrastructure at work. I highly recommend this hike.

I hiked to Lily Mountain on 11/3 and walked through a winter wonderland! There was only one group ahead of me on the trail and I am grateful for their footprints! In the snow this was certainly a bit more work but still a beautiful trail! I would certainly recommend having micro spikes, especially once you get closer to the top. The scramble at the top was worth the whole hike. I would recommend leaving your backpack or whatever towards the bottom of the scramble so you aren't off-balance as you climb up. There are a few spots i lost the trail, but found my way back to it. Having the map on the app was helpful!

Trail is difficult to follow after about one mile but by that point you’re just making your way to the summit. It’s unmarked and across the road from where you’re able to part. I would rate this at hard vs moderate. Loved it, views were so worth the climb.

Beautiful hike with some stunning views. Very heavily trafficked especially on the road leading to the Sleepy Lion trail, but everybody kind of spreads out after that.

Remnants of the old trail are still visible for 90% of the hike. It’s closer to a hard than moderate by my estimation. Climbing starts from step 1 and relents very little. But, it was a lovely hike without seeing another soul (human). We did watch Steller’s Jays, hawks and lots of other wildlife scurry about. The views are grand.

Did this counterclockwise and thoroughly enjoyed it. Fascinating mix of super wide gravel road, steep rocky single track (moments of scrambling even) and a descent on long deteriorating asphalt. Views were great and dam, causeway and canyon walls fun to admire. Dogs off leash on the single track only (about 40%) but that worked for me.

Nice views but mainly service road hiking. Well marked and plenty of water for pooches. Nice designated off leash trails for the dogs.

Beautiful views at the top make this worth it. The hike itself is pretty and a decent quick workout, but there are prettier hikes in the park if you have limited time. I did this one with my dog since dogs aren’t allowed to hike in the park. It is a dry trail with no water sources for the pups, fyi. Wasn’t very crowded during the week. No bugs that I saw.

This is a go-to trail, the only thing that keeps me from giving it 5 stars is that almost half of the trail is a dirt road, but there are beautiful creek views along the road. There’s a little bit of everything, shade, sun, flat, steep and great views. Bring sunscreen, the road has little shade.

The scramble at the top was too much for a 3 year old but maybe we'll do it again in a few years.

Great views! Not easy to get lost. LOL. Very straightforward. There were some rocky and steep areas, but overall, it was great. My dog loved it! There weren’t too many folks in the early am. I loved the views and that it was close to town. Great! And def moderate.

Pretty hike only 20 minute drive from Lyons.
Great views of reservoir and Longs Peak at the halfway point.
2.5 hours total.

Great hike with our dogs. Beautiful views!

It was ok. Got there around 9am plenty of parking.

gorgeous trail. When you finish the sleepy lion, take the hummingbird switchback trail for a beautiful walk around the reservoir.

More of a nature walk than a hike.

Beautiful...the rocks at the top were definitely intimidating!

an absolutely beautiful hike.
but KEEP IN MIND!!!! the location was DIFFICULT to get to!
This destination requires 4WD, a lift, mountain tires and experience lol!!! I was in my Jeep Wrangler (no lift) but luckily good tires and i was still holding on for dear life!

A pleasant family hike with beautiful views at the top of the trail overlooking the reservoir and mountain peaks beyond. Nice rock outcropping sniffer a perfect place to sit and enjoy an appreciated, nourishing repast with an exquisite view. The last half of the loop is a fire road which wasn’t as inviting of nature as the Lion trail on the way up. Lovely, nevertheless!

Nice open trail through the foothill shrub forests until you get to a higher up area with cool views of the dam/reservoir. Plenty of parking even when its super busy.

Beautiful trail but I will say the easy rating could be bumped up to moderate.

Sleepy Lion great for the small pup!

This was our first hike as a family, we brought our corgi and our 7 month old, who’s name happens to be Lily!! My husband wore Lily strapped to his chest in one of those baby carriers, and our dog was able to come along too! If your pooch doesn’t like climbing, this hike is not for them, parts of it can be a bit rocky, especially nearer the top. I thought the hike was perfect for our family!! Beautiful views. Not too short, not too long. Easy to find. Roadside parking. Remember to bring plenty of water and leave the trail in better condition than how you found it!! :)

My wife and daughter and dog had a beautiful hike.

Great trail with beautiful views!

There’s a great 360 degree view waiting for you at the top. Pack a lunch and enjoy the view!

Great trail! Arrived at 8am on a Saturday and the lot was less than half full. Mostly full by the time we left around 11am. The reservoir was awesome. Great hike with the dog. I’ll be back to trail run!

Gets slightly tougher towards the summit but the views are totally worth the hike. Moderate difficulty for some stunning views.

First time hike for my brother and I both. We went June 20th 2018 and the weather couldn't have been better. We took our time and really enjoyed the trail and everything along the way. The rock scramble at the top may seem discouraging but do not let that stop you, the amazing 360 view at the top is worth every bit of effort!!! Highly recommend this trail!
