County Highlight:  La Paz County


About La Paz County

La Paz County was formed on January 1, 1983. Since then tourism and agriculture have become the leaders in the county’s economy. The towns of Parker and Quartzsite are the main population centers, as well as the main business areas for residents and winter visitors.

La Paz County offers residents and visitors a combination of water and desert recreational activities. In the Parker area, water recreation is king. The 17-mile Parker Strip offers some of the best water for skiing, boating, jet skiing, wave-running, and swimming, as well as excellent fishing in the western United States. Desert rats will enjoy miles and miles of off-road trails, old mines and ghost towns, and beautiful springtime wildflower displays.

Quartzsite is known for its winter season gem and mineral shows. More than 1 million folks visit this community each year to take part in these shows. La Paz County offers a quiet pollution free haven to winter visitors escaping the snow and ice in the Northern and Midwestern states.


The International Association of Assessing Officers is a nonprofit, educational, and research association. It is a professional membership organization of government assessment officials and others interested in the administration of the property tax. IAAO was founded in 1934, and now has a membership of more than 7,000 members worldwide from governmental, business, and academic communities.
