- Encompassing 323 acres, the Arboretum is Arizona's oldest and largest botanical garden. It was the first purely botanical institution in the intermountain states. Since its early conception in the 1920's the Boyce Thompson Arboretum State Park has not only developed into a major center for plant research but has also blossomed into a lush desert garden containing regional plants and trees from around the world. These plants line the garden's scenic walks.

Boyce Thompson Arboretum State Park
The arboretum was founded in the 1920's by mining magnate Col. Wiliam Boyce Thompson. Thompson understood the importance of plants as the ultimate source of a large portion of mankind's food, clothing, and shelter. He was determined to use his great wealth to improve the use of plant resources.
Park facilities include the Smith Interpretive Center, visitors center, gift shop, Demonstration Garden, and picnic grounds with tables and restrooms. The visitors center sells a variety of cacti, succulents and water water-efficient trees and shrubs.
Recreation - Because the park is limited to day use only, there is no overnight camping, yet there are facilities to picnic within the shade of the garden's beautiful plants. Also there are opportunities to walk along the many scenic hiking trails. The visitors center offers seasonal lectures series and workshops.
Climate - The climate of Arizona varies greatly with elevation. Southern Arizona and the low elevations experience a desert climate. During the summer months, expect very hot temperatures with afternoon thunderstorms possible especially in July and August. Daytime high temperatures can exceed 100 degrees. Winter brings moderate temperatures to the low elevations, with warm days and cool to cold nights. Winter is a good time to experience these normally snow free areas. Fall and spring are transitional periods and can also be nice times to visit these desert regions. Be prepared for cool temperatures at higher elevations and dress in layers for your travels in this state of varying climates.
Boyce Thompson Arboretum State Park is located in south-central Arizona. It can be reached by traveling three miles west of Superior along U.S. Highway 60.
