The South Fork Owyhee River flows north through the Owyhee desert, joining the river's East Fork in southwestern Idaho. River-running in rafts and kayaks through the steep-walled canyon is the most popular recreational activity from late March through early June.

From Elko, travel 27 miles north on State Highway 225. Turn west onto State Highway 226 for 40 miles until the pavement ends. Then follow County Rd 728 for 16 miles to the Petan Ranch.
