<p>My suggestion is to go out via Death Valley Junction and Pahrump to Las Vegas. You'll approach Las Vegas from the Blue Diamond area on Hwy 160. Follow the directions for I-215 for Henderson. This route skirts the southern edge of the city and you'll never be in the busy downtown or strip area.<br>
From Henderson, take Hwy 93 to Kingman, then I-40 to Williams.<br>
This whole route is about 400 miles. You don't even have to go into Las Vegas; if you want to eat or buy anything, do it in Pahrump, Henderson, or Boulder City.</p>
