Take exit 188B off I-80 and head north on Hwy 89. Trailhead is just past the Prosser Creek Bridge on the right. If you reach Hobart Mills Rd. you've gone too far. The Emigrant Trail has a rolling-hill, out-and-back singletrack ride. Follows Prosser Creek then turns uphill to the left, crosses several dirt roads on its way to Stampede Reservoir. Great ride for a novice with excellent views of the Sierra landscape.
