Nestled at 7,150 feet in elevation, The Arboretum at Flagstaff spans 200 acres of breathtaking beauty, serving as a living laboratory for the native and drought-tolerant plants of the Colorado Plateau. This exceptional arboretum, often referred to as "The Arb," is a non-profit botanical garden, research facility, and environmental education center, offering spectacular panoramic views of the majestic San Francisco Peaks. Its primary mission is to foster understanding, appreciation, and conservation of the region's diverse plant communities, making it a vital hub for ecological research and public engagement.
Visitors can explore a variety of carefully curated display gardens, including an extensive Penstemon collection that is a point of pride, a vibrant Pollinator Garden attracting butterflies and hummingbirds, and the serene Water Conservation Garden showcasing xeriscape techniques. Beyond cultivated spaces, miles of family and pet-friendly woodland trails wind through forests, wetlands, and open meadows, allowing for encounters with both flora and local wildlife. Key attractions also include a seasonal Butterfly House, Frances's Kitchen Herb Garden, and the Mixed Conifer Habitat with its diverse trees.

The Arboretum at Flagstaff originated from the passion of one woman, Frances McAllister. The 200-acre property was first gifted to her husband in the 1930s as a wedding present, where they enjoyed a log cabin retreat each summer. McAllister later moved to Flagstaff permanently in the 1960s, building a new home (the Walter Reichardt House, now the Visitor Center) and dedicating herself to understanding high-altitude gardening in the arid climate. In 1981, McAllister formally founded the non-profit institute, donating the land and establishing an endowment to ensure its long-term preservation and educational mission. Her original log cabin is still on the grounds, a historical reminder of the arboretum's origins as a private residence transformed into a significant center for plant research and conservation.
Stroll through various themed gardens and woodland trails, observe native plants and wildlife, take part in guided bird walks, attend seasonal workshops or events, and enjoy a picnic amidst the natural beauty. The Visitor Center offers interactive learning opportunities, especially for children.
Spring (May-June): Expect chilly and windy conditions, with the landscape awakening and wildflowers beginning to bloom. Snow can still occur in May.
Summer (July-August): This is the peak bloom season and a popular time to escape the heat of lower Arizona. Monsoon rains might occur, enhancing the greenery.
Fall (September-October): Enjoy the rapid onset of fall colors. Early October might still see some snow.
Winter (November-April): The Arboretum is closed to the public during these months.
The Arboretum is a historic property with varying terrain, including grade changes and organic path surfaces, which may present challenges for wheelchair access. Visitors using wheelchairs are advised to inquire at the Visitor Center for a map of accessible areas upon arrival. The 3-mile access road is unpaved and can be rough, so reliable all-weather transportation is recommended.
Don't miss the extensive Penstemon Collection, the seasonal Butterfly House, and the Pollinator Garden bustling with insects and hummingbirds. Explore Frances's Kitchen Herb Garden and the Water Conservation Garden, or simply enjoy the panoramic views of the San Francisco Peaks. Look for the historic log cabin and the diverse trees in the Mixed Conifer Habitat. Participate in daily naturalist walks or raptor education programs when available.
