Location Shooting
Tohono Chul is a stunning location for photography and filming, showcasing the natural beauty and cultural richness of the Sonoran Desert. We welcome inquiries from photographers and filmmakers seeking to capture the unique landscapes and vibrant flora of our gardens.
Please note that we receive many requests, particularly during our busy seasons, and while we strive to assist everyone, our resources are limited. If you are interested in scheduling a shoot, we encourage you to reach out with details about your project at your earliest convenience.
During your visit, we kindly ask that you respect the environment by avoiding disturbance to plants and wildlife and ensuring that paths remain unobstructed for other visitors. Drones are never permitted on the premises without prior authorization.
Each member of your party will be required to pay the admission fee and you may be subject to additional fees based on the scope of your project.
Thank you for considering Tohono Chul as your filming location!
