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!

Perfect! Trails can get super busy as the day goes by. Most using the trails are courteous but there are plenty of mountain bikers who whiz past you so be alert.

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.

I live on this mountain and enjoy hiking here. It is busy during the warmer months, and as others point out, many bikers don’t share the path or watch their speed which is annoying but hey, driving 6th Avenue has the same issue so you get used to it. Watch for rattle snakes!

Easy, enjoyable hike. Great for a newbie to the area getting used to a little elevation (like me!) and still wanting some nice views without traveling too far. Saw some cool birds and a coyote.

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!

beautiful views! for my first hike it was well worth it!

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.

This trail was a lot of fun to run. The only suggestion I have is to be familiar with the trails before you head up the mountain. The kiosk at the trailhead has a trail map, but it isn't very specific and doesn't show distances per trail. Being a first-time on the mountain, I ended up talking to several friendly trail runners who gladly helped me out. Super nice weather!

Great walk. Windy today and some mud (

shows signs of a lot of people. too much bike activity with riders thinking mud is fun with no respect for the trail damage.

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.

Good for a close, early hills hike.

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.

Many bikers- great for a workout especially if you start the trail to the left.

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.

More of a mountain biking trail. Not great for hiking.

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.

This is a very nice trail extremely close to downtown Denver. My girlfriend and I hiked the largest loop possible starting from the lot west of C470. We started off going up the step incline to the left by the large rock outcropping... this may have been out first mistake. This path is nice and wide but a straight incline for well over a mile. We really liked all the different trail options and for being just an open space with no trees it was actually very pretty. Our only complaints about the trail is the different trail options aren't defined very well, gender the reason we took the largest loop, evening ending up on Alameda at ones point. The other HUGE complaint is this trail is an excellent mountain biking trail. We must have yielded to no less than 150 bikes in our 2:45 of hiking, and in some sections they are flying well over 20/30 mph.

Beautiful hike and has an amazing view of denver when you make it up! Wonderful for our dog as well

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

So pretty! You can see everything... downtown, the Flatirons, the mountains.
