No access until mid-summer. Crossing of Grizzly Creek dependent on water level.

Overview

A beautiful loop along two canyons cut by Grizzly and No Name Creeks. The start and finish of this loop are well trafficked by other runners, but you'll be alone for the middle portion of it.

Need to Know

The last half mile to the pass summit is 1000' of elevation gained, trail is overgrown. Do not attempt this after runoff as Grizzly Creek will not be crossable. Suggest doing this Grizzly to No Name because of the risk of Grizzly Creek not being crossable, and the steep ascent up Grizzly. Pants or tall socks recommended because of the overgrowth.

Runner Notes

Download Colorado maps on Trail Run Project mobile app to aid in route finding. The connecting portion of this is not well traveled and can be difficult to find. The trail disappears a few times, and there are a few junctions on the No Name side.

Description

Begin the loop at the No Name exit and run along the Glenwood Bike Path for about two miles until you reach the Grizzly Creek Rest Area. Go left at the upper parking lot to start your ascent on Grizzly Creek Trail #2065.

The Grizzly Creek Trail follows the canyon cut by Grizzly Creek starting at level ground and gradually becoming narrow and steep, with a few rock slide crossings. The trail ends at an old aqueduct. Look for cairns at the end and climb over a few boulders to the creek crossing where there is a log and a few rocks to cross over. This will not be passable in the spring and early summer.

After crossing begin the narrow and steep switchbacks up to the pass. It is helpful to have navigation at this point as it is overgrown and at times it is difficult to find the trail. After crossing over the summit continue down to the foot bridge and make your way down the gradual descent of Jessie Weaver Trail #1847 (No Name Trail).

This trail follows No Name Creek through the xanyon down to the Colorado River. End back at the No Name exit.

Flora & Fauna

Bear, deer, moose, song birds, cougar, big horn sheep, elk.

History & Background

Grizzly Creek received its name because of the largest grizzly bear on Colorado record being killed here in 1881.
