Great, dog-friendly front range hike. Got to parking lot around 8am and it was only half full. Took us 3 hours with a few stops for our pup, but could easily be done in 2. The switchbacks to the reservoir are worth the effort - nice spot to have a snack and relax for a bit. This seems to be a pretty quiet trail comparative to other hikes in the area. It does get pretty sunny and warm, so bring plenty of water.

Absolutely fantastic hike. This one has it all. With option to keep going further into hall ranch trails at the top. Was about to turn around at the top of sleepy lion in the large field before the view of the dam due to inclement weather but so glad I pushed forward. The sky went from dark most of the afternoon to a full 180 of afternoon sunlight. The river and dam portions are astonishing.

Great summer trail next to river. People were taking dips and cooling down. First part of trail is a road but then the loop is a great true trail with nice views.

Such a beautiful hike with amazing scenery. Good mixture of rocks and road. Make sure to do the Sleepy Lion Trail. Will be back for sure.

This is a nice trail to get away from the busyness of Boulder or other popular front range hikes. The reservoir beautifully frames Longs Peak. Beware that there is little shade on the road portion of the trail in the afternoon.

Very nice! Get there early to avoid people! When you get to the reservoir go up hummingbird switchbacks

Went backpacking with my 14 year old son. Camped down by the creek, had a great time. not too hard. We actually took a detour and hiked down to R.P. reservoir. very nice extra hike, but too bad we could not camp there. disappointed that there was a fire ban. we were also able to shoot our 22 before and after our hike at the open range at the trailhead.

This was a fantastic hike! You start out walking through cacti, crest into a gorgeous golden meadow dotted with wild flowers, continue on to the next peak where you can see for miles, then finish by the perfectly quiet reservior. and, during the week, I didn't see a single other person on the trail. such a hidden gem ❤️

A very enjoyable hike for a Sunday afternoon. As you'll see in the trail profile, it's mostly downhill on the way out, making the return more difficult. Starts out in the shade, then goes to a couple of open meadows (bring sunscreen!). I'd suggest continuing on a bit further than the map on AllTrails displays so that you come to the river - great place to hang out for a while. Some of the trail is eroded from use/flood damage, but there's usually an "up-and-over" alternative if you look for it. The directions for "Getting There" on AllTrails are helpful. I had no trouble driving there in my 2WD lower-clearance car.

I love this trail

love this trail was busy today but still not packed manged to add the new professional trail addition off sleepy lion to the dam. it is step but worth the effort.

Very moderate. Not too strenuous. Good mountain views.

Great hike with some unexpected views. There were a few steep portions so be prepared. I loved that it wasn’t highly populated. I went around 8:30 a.m. on a Sunday and only ran into a handful of people. Highly enjoyable overall.

Great trail with beautiful views. I especially liked the meadow. Started at 3 in the afternoon and did not see a single person - had the trail to myself! Definitely take the Sleepy Lion Trail up and around to the dam - prettiest way and a good hike. Some exposed areas and was hot but could quickly duck back into the shade. It intersects other trails I'd like to try too. No time to go up the Hummingbird Trail this time but plan on it next time.

Great views. Beautiful hike.

Nice trail not busy at all we seen three others all day

Great workout hike. Another one of my local favorites. The first time I did this trail I did the whole loop and did the hiker shuffle back to my car. I went up the nighthawk way and looped back down. Was a solid 9+ miles and I don’t even think I stopped. Oops. The views and scenery are amazing and I really liked the switch backs. Views are breathtaking.

Really stunning views. I went around 6-9pm on weekday. I was literally the only person on the trail. But campers were around. The road leading up is half dirt and sketchy in places for low cars. My prius was fine tho. Drive slow. The creek is pretty dry until half way in. When you get to the huge open field, keep going, until you see the trail split at the end, and go left into the next meadow. You will have to cross a broken path over the water, so you will know. Just more stunning views in the 2nd meadow too. Absolutely lovely.

Most of the trail would qualify as easy, but the trails at the northeast make up for it in difficulty in and around the crash site. All and All a fun site with a wide range of difficulty.

Such beautiful views here!

really fun my 4runner went through with ease on main trail and one of the branch off roads is when the fun started cant wait to go back!

Quite a beautiful hike, with a little peak at the Rockies. You get a little bit of everything, including a beautiful meadow. My only complaints are the dams and electrical poles, which would momentarily contaminate my experience in nature. But this is Colorado and water is scarce, so I guess it's to be expected. Overall, would recommend!

I almost hate to write a review and expose this place. Great hike from start to stop. Love the fact they have an are to let you dig of the leash. Just a great hike all round. I want to extend it next time with one of the hiking trails that intersect.

This is a great trail trail that remains fairly flat throughout. There is a waterfall half way in which is really nice and a couple meadows you walk through with the mountains in the background. We went early in the day and saw few people. Good hike with dogs as well!

This trail is a lot of fun but a lot of rental traffic that have no trail courtesy for other riders.

Excellent hike. Plenty of parking and easy access to the trail. Views are spectacular! Bring your dog!

awsome trail! dog friendly. like a mile up the hike/walking, the trail splits and a trail is for off leash dogs. my dogs had a blast been off leash. great hike. one of my favorites of all time.

This is truly one of my favorites! Very dog friendly and love the water.
