Greyrock Summit Trail Professional Reviews and Guides

"A warm, south-facing slope and some fun scrambling — spring hiking doesn’t get much better than this. For this early in the hiking season, a good hike will be on a south facing slope with not too much elevation, and in an area which doesn't receive a large amount of snowfall.

The Greyrock Mountain Trail meets all these specifications perfectly and provides some enjoyable, easy rock scrambling near the summit. The trail isn’t that well marked near the top and a wrong turn is possible. If that happens, double back and try again. The summit block is popular with rock climbers."

"This is a heavily used and very popular trail that is easily accessible from Fort Collins. The summit of Greyrock is of geologic interest: It is a massive granitic intrusion that has weathered to its rounded shape through exfoliation.

The summit block provides popular rock-climbing routes.Watch for poison ivy along the way. The trail near the summit is not marked, and over the years hikers have become lost and required rescue help.Dogs on leash are permitted."

"Greyrock Mountain is a big ol’ granite dome above Poudre Canyon, and the fun loop trail to the summit makes a great day hike. The hike travels over well-maintained tread to a peaceful meadow, then up and over some huge boulders to the summit and great views to the east.

The trail starts in the lower reaches of the ruggedly scenic Poudre Canyon, and crosses right over the Cache la Poudre River. The river offers fantastic fishing and whitewater rafting, and many campsites along its banks provide opportunity for extended stays in the canyon."

My daugther and I began this trek around 0930 or 1000 and finished around 1715 or 1730. Not in any real hurry, she let me take my share of stops up the mountain. She was a trooper and kept telling me werent stopping until we reached the top. We started out taking the meadows trail, up to Greyrock Mountain Peak, and then down the other half of the trail. We had planned to do the loop this way as the Meadows trail is longer than the other side and we figured we would be tired, which we were. The going was rough, but good. You have to be especially careful going up Greyrock, its extremely steep, but usually has a good spot to put a foot. (Tip if you go, you might see columns of rock, this are markers for the way to go, we didnt know that before we left.) All said and done, I think I would have preferred to come up the right hand loop of trail, and come down the meadows, not quite as steep, although it is longer. Word to wise, there is wildlife up there, to be expected. We ran across a black bear on the way back down the trail. It was very cool to see, and glad he didnt see us. What do you do when a bear starts chasing you and you are on this skinny trail. I would definitely do this trail again. Thanks to my daughter for suggesting this, not letting me stop, oh yea, and the four days of misery my calves had afterwards, lol.

Greyrock is the most heavily trafficked trail in the Canyon/Lakes Ranger District. It is accessible most of the year, even now 2 weeks after a 2' snowstorm. Its popularity has a lot to do with being only 20 miles from the 120,000 people in Fort Collins, allowing later starts and earlier returns to town. It has a couple of variations that increase or shorten the route with a bit of scrambling near the top, rewarded by impressive mountain and plains perspectives from the top. Round trips run 5-7 hours depending on route selected and speed of the hiker(s).

Beautiful half day hike. Taking the Meadow Trail up gives you a nicer view of the meadow when you first enter it. The meadow is at least as gorgeous as the Greyrock itself. Watch out for cactus. BTW, the initial ascent and the meadow seem to be great for backcounty camping.

Great trail! Close to town, and a good work out with nice views. Grab a post-hike beer at the Swing Station in La Porte.
