Utah is easy to reach whether flying into Salt Lake City or a regional airport or driving in from neighboring states. Interstate 15 runs north-to-south creating major intersections with the western terminus of Interstate 70 in Central Utah and Interstates 80 and 84 in the north. I-15 runs parallel to the Wasatch Mountain Range while the east-west I-80 intersects with I-15 in Salt Lake City, running up the canyon to Park City (or west to the Great Salt Lake and Bonneville Salt Flats).
Recent improvements to I-15 and a 70 mph urban speed limit means ease of movement among major cities along the Wasatch Front. It is about 45 minutes to Ogden or Provo, and 15 minutes more to the ski resorts in those areas. Park City and the Heber Valley are also under 45 minutes while the Salt Lake belt route, I-215 gets canyon-goers to the famous Cottonwoods (home to Snowbird, Alta, Brighton and Solitude) from downtown in under a half-hour.
It is a little more than 3.5 hours from Salt Lake City to Moab, gateway to Arches and Canyonlands national parks, or to Capitol Reef National Park. It's under 4 hours to Bryce Canyon and just over 4 hours to Zion National Park. Zion is about 2.5 hours from Las Vegas International Airport.
