Marana, AZ sits on the northwest side of Tucson and is only about 90 minutes south of the capital of Arizona, Phoenix. The town is bisected by Interstate 10, an east-west highway that takes a sharp turn north here and heads up to Phoenix and then out to Los Angeles. By land, Marana, AZ covers a total area of 121.4 square miles, starting on the line between Pinal and Pima counties and just north of the Tucson city line. This former farming and ranching community has become a suburb of Tucson and a top spot for retirees. Thanks to the nearly perfect weather and explosive growth in Arizona, Marana has experienced positive developments in housing, recreation and amenities that have made this town one of the most desirable in the area.
