This arboretum is a living outdoor museum with over 22,000 types of trees, plants, and shrubs. Visitors may wander through the Arboretum or join public tours. The Arboretum gardens are open 24 hours a day, every day, and are free of charge.

The UC Davis Arboretum was founded in 1936 to support teaching and research at the University of California. The Arboretum occupies 100 acres along the banks of the old north channel of Putah Creek, in California’s Central Valley. Collections include 22,000 trees and plants adapted to a Mediterranean climate, with hot, dry summers and cool, wet winters. The plants are arranged in a series of gardens that represent different geographic areas, plant groups, or horticultural themes.

Arboretum paths are popular with walkers, joggers, and bicyclists. The main path is a 3.5 mile loop. UC Davis sponsors the Aggies on the Move walking program for students, faculty, and staff.

The lawns at the west end near Peter J. Shields Grove are perfect for informal games and picnics. Picnic tables are located behind Putah Creek Lodge and in the Redwood Grove.

For the safety of visitors and wildlife, dogs must stay on leash in the Arboretum.

The west end of the Arboretum and the Arboretum Terrace Garden at the east end of the Arboretum are level and most easily accessible to wheelchairs and people with limited mobility. Disability accommodations will be provided with advanced notice. Please call or email at least two weeks in advance (contact info below). PDFs of educational exhibits for visitors with limited mobility are offered.
