Travelling by car to Las Vegas for the weekend is a favourite activity of people in the nearby Californian cities. The Interstate 15 comes from California into Las Vegas. It is paramount to drive safe since it is a very long stretch of speeding cars, and one mistake could lead to a massive pileup. People coming from Phoenix take the Interstate 40 before joining the Interstate 15, and from the north connect to Interstate 15 from Interstate 80.
Companies like Greyhound, Megabus, LuxBus and TUFESA connect the city very well with destinations like Los Angeles, Salt Lake City, Phoenix, San Diego and even part of Mexico.
