Good hike if you’re following it up with another trail in the area- on its own it’s not much

Lots of great trails that branch off of this one

Beautiful views the whole way up and great reward at the top

I did this hike with 2 other friends and had an incredible experience! None of us are really experienced hikers, but we're active and this was a hard hike for sure. My legs are sore while I'm typing this but totally worth it. We got a bit turned around a few times on the way down and almost found ourselves on an unfamiliar mountain path with no flashlight, but we made it just in time. It's cold and very windy on the way up this time of year so pack an extra jacket if you're not used to the weather!

Lots of stairstepping and strenuous, and a great view from the peak

Not sure why this is rated hard. It’s moderate at best. Maybe because of the length of the trail? Maybe the one short steep section? It’s definitely suited for trail running and biking, but hiking it was cool too. There’s a lot of gradual rolling hills with tree covered areas, sun exposed areas, a rushing river, good views of the back of Eldorado Canyon...lots of variety and scenery here.

I went counter clockwise, and it was pretty downhill from there. There’s a long gradual incline at about mile 6 to the end. The trail is well marked and easy to follow. After mile 4, there’s a parking lot. No need to go to the parking lot, just take the 2nd trail on the right, back to the original parking lot.

We intended to take the Goat Trail to East Ridge route up to Mount Sanitas but accidentally took a left turn at the top of Goat Trail. So we took Sanitas Valley, turned right to hike up Mount Sanitas, hiked down East Ridge, and back down Goat Trail. Beautiful views, a bit rockier than expected, and a great workout.

The most memorable moment occurred on Goat Trail about 5 minutes before we reached our car. Due to the rockiness, my gaze had been focused toward the ground as I took each step. Thankfully, I stopped to take a break, looked up, and saw a huge, majestic buck with beautiful, enormous antlers facing us about two car lengths down the trail. To say I couldn’t believe what I was seeing is an understatement. I’m 5’1”, so his presence seemed even more impressive to me. Being relatively new to hiking, I wasn’t sure what to do, so we backed away slowly and stepped off the trail next to a boulder. I thought maybe he’d turn around, continue right past us on the trail, or run off. Instead, he walked toward us, stepped off the path exactly where we had, passed right by us on the other side of the boulder, hopped to the side of the hill opposite of us, and started climbing. Amazing!

More on the moderate/hard side. Steady incline but the short distance makes it easier. Perfect, quick hike!
