Ceran St. Vrain Trail - 3.85 Miles Round-Trip

The Ceran St. Vrain Trail closely follows a two mile stretch of South St. Vrain Creek, whose origin lies with Isabelle Glacier atop the Continental Divide some 10+ miles away and 3,700' above.

Trail Map | Photo Gallery

The trail is named for Ceran St. Vrain (1802 - 1870), a fur trader, politician and settler who established several trading posts and military forts along this creek and the South Platte River.

This mild trail leads through pristine upper-montane forests, an inclusive ecological transition zone of lodgepole pine, spruce, fir and aspen. The riparian corridor it follows supports bigtooth maple, thin leaf alder, box elder and willow, which combine to produce brilliant autumn colors.

Summer flowers thrive along the creek, notably columbine, wild rose and the prized Fairy Slipper Orchid. Visitors will enjoy good trail conditions, mild grades, easy stream access, desirable backcountry camping locations and excellent fishing:

The trail begins over a long bridge with good up and down-stream views. Once over it turns north and undulates mildly up the creek's west bank with little net elevation loss to its unofficial terminus at the 801-252 Jeep road split (1.92 miles : 8,105').

The trail is generally clear and well-padded from layers of fallen pine needles, but negotiates a few high, narrow ledges on the first half mile that are tricky when iced over. Beyond that, it travels easily through intervals of mixed pine, narrow-walled passages, and broad stream shoulders.

Though campsites are unmaintained, many are well-established and easy to find.

No sign marks the trail's end, however it suddenly widens at the 801-252 4WD Jeep fork. A good map will lead you up Road 801 to another series of dirt road connections and unmarked trail spurs, one of which scales the summit of Miller Rock (8,646').

"Trail is now clear of trees....thank you to the crew that did it! I recommend going further to Miller's Rock for the outstanding views."

"Trail is open but there are MANY trees blown down across the path, which you must climb over, under, or around."

"Great trail. A little steep in some places, but overall very leisurely with great views. There was a fair amount of people. Once I got past the campers, though, it was pretty quiet. No snow, my dog loved playing in the stream. Very pretty."

"Ran this trail with both dogs. The trail was almost completely covered in snow but the snow was already packed down by skis / snowshoes. Beautiful rolling trail. The service road (to Miller Rock) at the end was almost completely dry and had great views from the top."

"Is there any prospecting on this crk?"

"Beautiful hike. I continued up to Mitchell Rocks and took a lot of photos. I didn't realize there were campsites. I will definitely be coming back to check that out. One word of caution is that the mountain bikers aren't always aware of the hikers especially given the blind corners on the trail. I was almost run down on the the way back because the biker was going way too fast."

"A beautiful easy hike along the creek. Many hikers do not respect the dogs-on-leash rule. We'd like to come back and camp."

"This is a great trail but there are a lot of people on it. The trail is a little to thin in areas so it makes it tough to get around other people at some points. I will continue to hike it because of the beauty of the area. "
