White Rock Canyon Wash is a nice trail to enjoy with Fido. The trailhead is located on 93 Northbound. To get there from Las Vegas, you take 93 Southbound past the Hoover Dam about 4 miles. You will then need to use the crossover to get to 93 Northbound. You will actually pass the trailhead and need to backtrack. The trailhead is clearly marked. Make sure to bring plenty of water for you and your pup.
