This thriving town of just under 110,000 people is a focal point of Orange County. Originally, Spanish missionaries built a small way station used by cattle herders and, by the 1880s, it began to grow. First as an agricultural area known for its orchards and during World War II as the site of Santa Ana Air Base, a key point for the war in the Pacific.
Costa Mesa has a few areas that are surprisingly walkable, most notably the Pinkley Park area. Although beautiful, Fairview Park is not very walkable and should be avoided by those without a car. The public transit in the area is run by the Orange County Transportation Authority and covers most of the city. Bus frequency will be an issue for most, however, as the normal bus routes will not run over the weekend.
