Nice trail accessible by public transportation. When I went last night I watched a herd of elk grazing right off the trail in the sunset.

I mean it was a decent hike. but the climb up, while physically challenging, was honestly boring. it's just dirt and gravel everywhere, there's no shade, and when we went (mid August) there were bugs swarming at our faces and biting our necks. it felt like a desert. the view was nice, though. and yeah there are a lot of mountain bikers, but there's usually enough room to let them pass.
probably wouldn't do it again for fun, but for exercise it's good

Ended up being 6 mi trail due to being poorly marked. Not to shabby otherwise though!

Good long trail. Ran in to a herd of 12 elk, and also saw a mile deer. Took part of the Rooney trail through the valley as well.

great hike. loose gravel makes it slippery at times.

A great option for a runner that is new to trail running! I was hesitant to run this trail because of the previous snake warning, and though I didn't cross paths with one, I was warned when I got back to the parking lot that one was spotted on the near by Summit trail. Use caution and always stay aware!

I've been hiking this 4-6 times a week for the last 3 months. I also mtn bike all of GM. A few days ago, I encountered a very large rattlesnake on the single track part of the trail just before the tower. After striking at me once and thankfully missing me, I quickly backed up, but he slithered toward me and struck again and I again moved back, he advanced and struck again. I used a hiking pole to throw him well off the trail. It is best not to aggravate them with rocks, dogs, sticks, etc. if you can't get past or even if you can and you have some way to move them well off the trail, please do. Any aggressive poisonous snake is a dangerous snake. Be careful, especially with small children and dogs.

Beautiful scenery and saw elk out and about. Close to Denver which is nice and you will see the roads and cars driving around you for a good part of the hike

5/21/18 start 5:30pm. First of all, this is categorized wrong. It’s an easy trail, not moderate. It’s also boring compared to countless other trails you could hike. This should be classified as MOUNTAIN BIKING ONLY. The paths are relatively wide in a lot of places with no real technical hiking challenges. In the places where path was not wide I had to get out of the way for WAY too many bikes. Never ever had to say that before about a trail. One bike guy announced himself from way up the hill and then came charging down at freight train speed. Scared me to death and almost lost my balance. Dear biker: you don’t need to be going that fast on a trail with hikers. Won’t be doing this trail again.

Had a nice hike here today. We brought our dogs and luckily we had some cloud cover. It was about 6.6 miles from the car and back. The hike was great, lots of ups and downs and some good incline. My one complaint is that there is no tree cover. It is really just a wide open meadow and field. We were fortunate with the cloud cover today but I wouldn’t bring a dog back here during the summer months knowing how hot it gets, the rattlesnakes and the lack of any water or shade cover. Other than that we saw lots of runners and bikers. It was a good trail and I think we were lucky with the weather today!

The view at the top is nice but I'm not sure it's worth having to listen to the highway, consistently moving out of the way for mountain bikers, and being very hot because there is no shade.

I've really enjoyed this hike over the last couple of weeks. The weather has been wonderful. Only downside is that myself and my friend both slipped while hiking the last mile as a result of all the loose dirt and gravel.

My wife and I hiked wearing our one year old and waking our dog. Nice views of Denver and it's suburbs.

Not bad. Not great.

This was an awesome trail with a beautiful view. It was windy 3/18 and there were mostly mountain bikers but everyone was extremely nice and respectful of all trail rules. 10/10 might be back next weekend!

Lots of bikes, but the trail is more than wide enough for bikes and people. Not a peaceful hike if there’s a motocross race going on across the road.

Hardly any mud left - a couple of spots but nothing tennis shoes couldn’t handle. Pretty low traffic at 10:00 on a weekday - picking up by the time we left. Easy hiking for our 25 lb pup.

Great walk. Windy today and some mud (

This was a great hike- BUT- be warned! It doesn’t have a huge vertical but it happens quickly (you are basically climbing straight up the Green Mountain). It was too much for our low-energy dog, who needed to take breaks several times going up (we didn’t mind because we needed them, too!). I went on a weekday when it was 60 degrees, so it was crowded but not terribly so. The bikers were respectful, as were other people hiking with or without dogs. The trail is big enough for everyone to share the space. The views were gorgeous!! Especially on a day with a clear blue sky.

This trail has been taken over by bikers. Even though the ordinance by Lakewood Regional Parks requires bikers to yield to walkers and hikers, that is not the reality. Parks should change this park’s rules or tell bikers to change or leave.

The trail was just fine but, the description in the app was not accurate. I planned for a 3.2 mile loop, by myself, unaware that there are several loops. I ended up hiking over 6 miles and not knowing where I was. I wound up in a neighborhood and fortunately a woman headed out for her hike directed me back to the parking lot.

I liked this hike more than I was anticipating! Even though it is literally right off 470 it’s great. The first 1.2 miles is moderately steep incline to the top when you go to the left. The rest is smooth sailing downhill. Great view of Lakewood/mountains from the top and 470 actually doesn’t ruin it! Finished the 4 miles in an hour and forty minutes, so great for a quick hike/work or close to home.

Nice hike very close to Denver. I was pleasantly surprised with the terrain after you cross the freeway and start on the trail. The top offers a tremendous 360 view; clear views back into the mountains and of downtown Denver. There were a lot of mountain bikers and it also seemed to be a great spot to trail run if hiking isn’t your jazz. You’ll be sure to be greeted by the chorus of prairie dogs. Keep an eye out for rattlesnakes as we saw one about a quarter of a mile in. Overall, definitely check it out especially for the view at the top. Over and out.

Easy walk

A good trail but I brought the wiener dog with me and it was a bit too much for him this time. Great views of Denver though

Fair trail close to city. Be careful for rattlesnakes.

Very moderate of not easy. Pretty noisy with road traffic. I work in lakeside do its a god hike near my office. I would not choose it as a first choice. Good fir mountain biking.

North route is steep dirt road without much to see. South route longer but more naturey. Terrific 360 degree views from the top where you can clearly make out downtown, the Flat Iron, Pike's Peak and Red Rocks. Nice wild flowers.
