Open year-round, the Arboretum (or “Arb,” as many visitors say) is best known for its beautiful display gardens, award-winning tree collections and natural areas. The Arb features miles of trails in all seasons, including paved paths, cross-country ski and snowshoe trails and Three-Mile Walk. The Oswald Visitor Center includes a casual cafe and outdoor terrace, Gift and Garden Store, art galleries and Great Hall for many seasonal displays and events. The adjacent Snyder Building includes the Andersen Horticultural Library and a conservatory. Venues and meeting spaces available for gatherings, business meetings and weddings – large and small. Open year-round. The Arb ranks among the Top Botanical Gardens by USA Today Readers Choice (#1 in 2019 and 2017) and has received level IV accreditation through ArbNet, an international community of arboreta.
All members and visitors must make reservations in advance of their visit to the Arboretum.
