The Dallas Arboretum aims to remain open 362 days a year. Occasionally, we are forced to close due to natural disasters, or open late in the event of snow days. Stay close to our Facebook and Twitter if you are concerned about unexpected closures.
We also keep the garden open late during some festivals. You will see this information posted on the home page of our website and across social media well in advance of those nights.

Administrative office open Monday through Friday, 8:30 a.m.-5 p.m.
