A long descent or long climb depending on the route taken, and ride above the lake.”
— Adrian Whitmore
The Narrows Bluff trail is aptly named by the sometimes narrow trail filtering through large rocks along the majority of the trail.
Heading north from the Dam overlook and getting on the trail, you continue north and skirt Glendo road along the way. The trail encounters a metal THAD device, continue over it. You'll meander north through pine and sagebrush, and the occasional cacti will be visible from the trail edge.
The trail then comes to a set of stairs made out of the local rock and - about 12 steps in total. It might be rideable by good riders, but is walled off on either side. Continue in the downward direction of the trail; rising and falling over a well-laid trail that falls below the cliff line. There will be great straight shots and and little rock obstacles along the way, and then the trail corridor will tighten, and slow you down.
You'll have the Glendo Lake on your left and the view of Laramie Peak in the distance. You still keep flowing the undulations in the trail.
(Note: In the summer months as you ride around through each cove and the trail goes in an out of the cliff face, you'll find the temperature extremes may be tiring. You can come out of the cove and hit a open area and it will be 70 degrees and back into a cove and hit temps of the upper 90 's or higher. This occurs sometimes due to the inability of the wind to access the cove, and the open sky above allows the sun to beat down. This is a bigger concern when taking the trail as an uphill.
This trail will then continue to meander along the cliffs and through the pine forest along the outcrops till you near Sandy Beach. You'll then find a floating bridge, when water is high the bridge floats, but when the water is low due to outlet flow the bridge will rest on the lake bottom. You then continue to the parking lot at Sandy Beach.
