GREYHOUND

Greyhound offers the most extensive intercity bus service in North America. San Diego is no exception: the city is well connected to the rest of the country, especially to Los Angeles, which takes about 3 to 4 hours to reach, depending on traffic. You can easily reach other states, such as Nevada (10 to 12 hours to Las Vegas), Arizona (about 14 hours to Phoenix) and Utah (about 20 hours to Salt Lake City). Unsurprisingly, the fares are cheaper than the train.
