The new Winnemucca Mountain trail, starts above Sage heights (near the dog pound). you can take a mile loop, a 3.5 mile loop, or go 6 miles to the summit of the mountain, the views from there are amazing.
If you dont feel like climbing all that way you can also get a ride to the top and ride down.
A good place to park is at the Sage heights pool or Veterans Park. The road behind the houses leads you directly to the trail head.
