Great trail and easy to choose how far you want to hike, not just a set loop size. Loved this trial, great for dogs.

It was a very nice hike other then the fact that there is no shade what so ever and it was 90° outside. It would be a great hike to do on a cooler day. I also want to go back one day and try out all the ziplines.

Aloha inter webs, I enjoyed this hike a lot. The parking lot was very full this beautiful sunny Saturday but the trail was not that busy. Social distancing was happening by everyone I came across. I love how these trail loops weave in and out of the Zip Line Tour platforms and I am sure it is something cool to see people on the zip lines while hiking through the hills. I hope they can open again soon.#letsgoforawalk

An excellent trail for a quick walk and is dog friendly. Just watch out for the ice patches in a few spots through out the trail.

Here is the link to the full trail system at miller park. AllTrails does not have the listing for the Purple and Gold trail. http://www.crgov.com/DocumentCenter/View/9314 If you start directly across from the Core Plaza and stay on the outer loop until you meetup with the Purple loop, then run Purple, Gold, Green and Red (red is flat and easy). The entire run will provide a decent, not too difficult workout. Finish it off with an accent up Challenge hill. Also on the Northeast edge of the Gold trail you can take the pedestrian bridge across to "Ridgeline Open Space" trails (see AllTrails listing). After your run dip your head in the fountains and lay in the grass and relax a while.

Decent enough trail. Great to start off your trail running training for beginners or starting up again. It is easy on the knees!

Solid trail and well marked. Definitely will get muddy come spring time. Saw quite a few deer and a pair of small bucks sparring. Had great Janruary weather with no wind, comfortable temp and overcast sky's. My major complaint is all the zip line set ups you walk by constantly along with the noise of city. All and all the pup and I enjoyed ourselves.

Great local hike right in the Philip S. Miller Complex! Their are more trails that you can link together if one requires a bit more distance, but this was enough for the time we had. Although we didn't experience this, we heard horror stories of mountain bikers hauling down the trails while hikers were on it, could be potentially hazardous.
