Visit us today!

Our mission is to educate our community, to inspire conservation, and demonstrate how both native and non-native flora and fauna can survive in an arid, high desert environment. Over 4,000 native and adaptive plant species are on display within the gardens. Visit during the spring and summer to see the flowers come alive and put on a dazzling display, or in the fall as the trees show their true colors. Take your time and explore; like a museum’s rotating exhibits, changing seasons mean no two visits to the Arboretum are the same. 


The Arboretum & Botanical Garden is open year-round during regular park hours.

Spring/Summer:  8 a.m. - 9 p.m.
Fall (Day after Labor Day to fall time change): 8 a.m. - 7 p.m.
Winter (Fall time change to spring time change): 8 a.m. - 5 p.m.

GETTING HERE: We are located within Rancho San Rafael Regional Park, 1595 N. Sierra Street, Reno, NV 89503.

Map of the gardens


The May Arboretum grounds are composed of both paved and packed gravel paths. Paved surfaces are usually wheelchair accessible. Gravel paths may be wheelchair accessible when dry, but can become quite muddy if the weather has been wet. In the event of a snow storm, both paved and gravel paths may be temporarily inaccessible to wheelchairs and other modes of mobility. Service dogs are allowed in all areas of Rancho San Rafael, including the May Arboretum.
