Boyce Thompson Arboretum State Park

Boyce Thompson Arboretum State Park is the oldest and largest botanical garden in Arizona, established in 1924 as a research facility dedicated to desert plants. Located in the Sonoran Desert, the 392-acre arboretum features a variety of plant life along Queen Creek, with Picketpost Mountain as its backdrop. Its focus on desert flora provides a unique opportunity to observe the beauty and resilience of arid landscapes, while also serving as an important site for conservation and education. Visitors can explore a network of trails that meander through different plant collections, take part in guided walks, and engage in family programs designed to connect people with nature. The park is accessible from U.S. Highway 60, approximately an hour’s drive east of Phoenix. It is important to prepare for the desert environment by bringing water and wearing suitable clothing for the weather. Parking is available on-site, but please confirm details regarding hours, fees, and any potential closures with the managing state agency before your visit.
