The Tuolumne County Airports Department manages two airports:
  • Columbia Airport provides service to Columbia and the surrounding area with multiple runways, a variety of businesses, and even a fly-in campground.
  • Pine Mountain Lake Airport services the area around Pine Mountain Lake.

Mission Statement

The mission of the Airports Department is to provide safe and efficient aviation facilities for Tuolumne County and its visitors through our commitment to quality services for all airport customers and by supporting our aviation and local communities through fiscal responsibility and professional competence in all airport activities.

Due to COVID-19, the Airport Campground will remain CLOSED until further notice. 

We recognize that certain areas in the county can open, however after careful consideration and in conjunction with the county’s public health officer, we have determined that due to the ongoing COVID-19 pandemic and our staff’s limited capability to provide a safe and clean environment, the campground will remain closed until further notice. We apologize for any inconvenience and we look forward to seeing you as soon as the campground can open safely.

If you have any questions, comments, and/or concerns, please do not hesitate to reach out to the Tuolumne County Airport office at 209-533-5685 at your convenience.

Tuolumne County continues to actively monitor the evolving situation related to the coronavirus (COVID-19) to provide safety to its community and traveling public.  Out of an abundance of caution, the County has determined to cancel the 54th Annual Columbia Airport Father’s Day Fly-InWhile this event is not held until later this year in June, there is no guarantee that the current stay at home orders for California will be lifted, and if they are, social distance orders will likely remain in effect for some months after.  The County is truly sorry to lose such a time-honored tradition to our community, both flying and local, and look forward to providing a great event next year.

Due to COVID-19, the Columbia Airport Campground is closed until further notice.

If you have any questions, comments, and/or concerns, please do not hesitate to reach out to the Tuolumne County Airport office at 209-533-5685 at your convenience.
