This trail is only difficult because of the shale covered boulders. The trail goes up and down a lot so you have to walk slow and carefully almost the entire time to stop from slipping. That part wasn’t that enjoyable. The views are great and the river is beautiful but there are better hikes IMO. The verticality isn’t that strenuous, the footing is just very soft.

My wife and I could not finish it, we ended up turning around at the 3 mile mark, the trail was getting too rough. The trail is on the side of a hill and parallels the South Platte River. We are not novices, we hike every weekend, but we did not feel comfortable continuing on, there are some boulders you have to navigate around and some very steep (but short) parts of the trail

However I would recommend the 6 miles out and back we did, the scenery is gorgeous.

Awesome hike! Take plenty of water. This is a tough one!!

Where to Park: You will park in the Cheeseman trail lot.

You will find the path to the trail head past the “fancy” outhouse. Take that path over the wooden bridge. The path splits, go left. You will walk about 50 yards and come across a dirt road that interrupts the path. Just walk across the dirt road and the path picks back up across the street. You will walk about 1/2 mile through the woods/trees and come across the actual trail head and map of the trail.

The Trail: the GILL trail runs along the water that leads to Cheesman Lake. Its and out and back.

Suggestions: Bring plenty of water 100oz or more and have at least one hiking friend

We are VERY experienced hikers and this was a Incredibly challenging. The trail is very challenging to follow and the last mile to Cheeseman Lake was a lot of climbing and bouldering.

The views are BEAUTIFUL!

Great little hike. We took the dog with us and he seemed to enjoy it as well. Some hard scramble spots but the dog and I made it through with no issues. Beautiful views of the river from every angle!! Would do it again.

Definitely one of the best trails I’ve been on! Unfortunately, I didn’t finish because of the trail being destroyed from mud slides. I spent maybe 30 mins trying to find the trail. I had less then a mile to go. But decided to turn back. If you like huge boulders and a trail that follows the stream this is for (you).

I saw a lot of people fly fishing throughout the trail must be fairly decent.

I’ll be back!

Really beautiful along the river. We really didn’t see a point in continuing past the point where the trail separates from the river and goes towards the reservoir.

This is a beautiful trail along the Platte River. WE wondered why it was rated as hard until we got to about mile 3.5 and it was a scramble to get up so we decided to turn back. There are some places that are extremely narrow and the footing is soft. Hoping to go back and complete this at some point. The trail has markings but they are not well defined and we did stray a few times from the trail unnecessarily.

oh boy. today was an adventure! first, the beware of the bathrooms at the trail head . . . no toilet paper and garbage all over the floor - if I would of had a garbage bag with me, I would of gladly cleaned it up.

the beginning of the trail was quiet and beautiful and then it got hard to follow. luckily I ran into an older couple who were having the same issue so we decided to hike together. the only real helpful (if I can even call it that) sign on the trail was nailed down to a rock with dotted lines in a circle that stated where there was water access, the gill trail or the upper cheeseman parking lot. we wanted to get to the reservoir so we stayed on the gill trail which ended up being a dead end. so we back tracked and took the upper cheeseman parking lot trail which did eventually lead us to views of the reservoir but at this point we were at 5.5 miles. the signs at the trailhead made it seem like you could hop on the road and get to the original starting parking lot fairly easy, but that wasn't the case. we figured hiking back almost 6 miles was a little far. we ended up hitching a ride to the starting parking lot by some friendly folks who had just came out from backpacking on the goose trail.

overall this trail was okay, I kind of wished I would of spent my Sunday hiking something worth while. and there isn't anything hard about it except staying on the actual trail and then having the desire to hike all the way back to parking.

Great hike with beautiful views! Not sure I’d say it was hard though, maybe moderate. Watch out for snakes!

Had a fantastic hike here today with a buddy- weather was fantastic and lots of friendly fishers were at work in the stream. A bit of small climbing areas if you stick on the higher trails but overall pretty manageable and a great workout- leaves you feeling satisfied when done!

Hiked this a week ago on a beautiful, warm, April day! Not one speck of snow. I would not consider this trail hard...a lot of ups and downs and scenic views along the river. I parked at the canyon trailhead on road 126 so I went all the way to the dam turn around (warning signs saying no trespassing) then turned back and took the trail leading to the other parking lot. If you park at the canyon trailhead definitely take the trail at the rock split (it's obvious, there is a map on a rock), otherwise you will miss awesome views of the reservoir! Once I got to the higher parking lot on road 211, I walked/ran back on the road which was definitely faster than taking the trail back. Sorry I don't remember all the parking lot names! If you are more of an advanced hiker, this really is not a workout or hard hike. I would recommend this more for a peaceful nature stroll!

Happy hiking!

Great, steady up and down. Didn't make it past the loose gravel at the 4mi turn because of older dog. Beautiful views of the river.

Very enjoyable hike along the beautiful Platte River and eventually winding up to nice views of the reservoir. You can make this a loop by taking the trail to the lake and then taking the road back. According to my GPS this made for about a 7 mile hike. The trail can be tricky to follow along the river. As others have mentioned, stay to the right when possible. We got into a couple of tricky spots trying to climb the hills to find the trail again. It was very quiet the day we were out (it was also 12 degrees), but i can imagine this is very busy wish people fishing when the weather is nice.

I adore this hike. Trail is difficult to follow and there is a lot of loose gravel, but it’s a fun challenge with an amazing view. Rule of thumb for our crew was to stay the right when heading up and left when descending. The trail follows the Platte River, so if you find yourself off trail then follow the river edge. You’ll eventually hit a river access trail that leads back up to Gill Trail. With the exception of one river bend I would probably rate the actual hike as moderate, and not difficult.

Fun hike, bunch of switchbacks, great view of the damn, glad the area is still restoring itself because it was cold out and the sun allowed us to be quite warm otherwise a shaded hike would’ve been freezing. I recommend this hike especially with a furry companion. :)

Great water views, some rattle snacks scars

Hike is not a loop, but out and back. Still a great hike with some good views and a nice river.

Gorgeous day to view Cheesman Lake! We hiked on a Wednesday-no other hikers on the trail but did see a few fisherman on the river. We started at the lower parking lot area, first 45-60 minutes of hike-easy. Getting closer to the lake was pretty difficult-lots of loose gravel, pretty steep and hard to follow trail but the view when you get there (top parking lot-has road access) is worth it-we hiked back to the lower parking lot via road. About 4 hours total-with a few pit stops to enjoy the views.

I'm not sure what Kyle below was talking about because the trail was beautiful. The beginning of the trail had a lot of the downed, burned trees he was talking about but once you got towards the river, you didn't see that any longer. We didn't make it all the way to the other end where the Cheeseman Canyon trail head was because the trail got really steep and was washed out with a lot of loose gravel which was out of my comfort zone. The river was so crystal clear you could see fish from way up above. The wild flowers were beautiful too. Not a lot of hiker traffic, mostly fisherman.

Would have been one star if not for seeing some fish in the river at the end. Scenery is HORRIBLE. How has no one in these reviews mentioned the forest fire which has completely killed away any fauna or flora. Miles of downed and burned trees. Hard rating is accurate. Lots of loose gravel and very steep although relatively short hike. DO NOT recommend. Hiked 6/5/17

Enjoyed the hike with adult family, it is was not much cooler than home in Centennial so take plenty of water if the weather is warm. good view of the Cheeseman Reservoir and the dam, mostly used by fly fisherman. Moderate rating comes from the last section, there is a fair amount of elevation drop and loose granite down to the river. Not very crowded as there were about 5 groups of hikers and people with fly rods we passed on our Sunday outing June

Great trail with spectacular views of the lake and dam. Didn't see another hiker the whole trail. Went down to the river and ate at the picnic table at the bridge area. Parking at the top as suggested is the way to go. You even have a bathroom.

Nicely maintained trail, dogs welcome on leash. Listed as hard, but easy to intermediate.

Sunday, April 16, 2017

Park at upper lot. Starts off with steep switchbacks and then levels out. Beautiful views and you can follow it down to the river if you want.

Sunday, March 12, 2017

Great hike. A little confusing on where the trail actually is. We parked at the upper lot and hiked the stream all the way to the dam to the lower lot then hiked the dirt road back. Plenty of spot to rest along the stream to watch fisherman.

Sunset hike in February! The trail was well maintained but the trailhead was not named "Gill Trail" Instead, the winding dirt road (Wigwam Creek Rd) lead down to a parking lot with a sign for "Canyon Trailhead" If you follow the directions posted above it will take you right to the parking lot at the base of the lake. We were driving a sedan that struggled a bit with clearance to get in the parking lot.
The trail starts with a pretty rambunctious inclined switchback, winds around trees, and then drops to the river and the dam. Because the trail wraps around the side of foothills, you are able to see the lake and the surrounding peaks most of the hike. We hiked the out and back in 3 hours with multiple stops to take in the scenery and watch the sunset. The only way this hike would have been more pleasurable is if it went all the way around the lake!

Nice trail. Well maintained with signs throughout yet didn't see one person the whole hike. The trail starts with an incline, levels out, and goes to a decline to a really nice view of a dam and a River in a canyon if you go far down enough.

Great trail with gorgeous views of the lake, dam and Arkansas River. Trail is well maintained, although recent wind storm knocked a few trees onto it in a few spots. Hardly anyone was on the trail except for a handful of fly fishermen. Took my dogs and they loved it. Spotted two mountain goats up close too. Looking forward to going back.
