The interconnected nature of the Greenhorn trails allows for a wide variety of loops. All the drainages are linked along the western divide. For hikers, many of the loops are longer than they may want to travel in a single day. There are several shorter options between the Cow Creek and Mahoney Gulch trails. Out-and-back hikes are also a great options on both the Greenhorn and Imperial Gulch trails.
The motorcycle community was instrumental in the development of the Greenhorn trail system; including funding trails construction that now allows improved connectivity to the Deer Creek and Warm Springs Creek trail networks. Funds generated from the sale of annual idaho motor-bike license stickers paid for a lot of motorized specific trail development in the late 1970s and early 1980s. All of the trails in Greenhorn Gulch are multi-use and open to all. Please respect each other and share the trails with a smile, just like our local motorcycle riders do.

The Cow Crk. Connector Trail departs the trailhead at the west end of the parking lot - near the cul-de-sac at the far end of the trailhead road. The trail quickly gains a hill providing a good overlook of the area. Climb one, two, or more of the turns for a short, but nice out-and-back hike from the parking lot. Go all the way up to the footbridge to reach a nice destination at burbling Cow Creek. The flowers along this trail are often outstanding in the springtime.
