Tips for Visiting Dumbarton Oaks #

- Arrive in the morning to experience the gardens at their quietest and to see the best light on the formal terraces and woodland plantings; combine the garden visit with the small museum of Byzantine and Pre-Columbian art, which many garden-focused visitors skip.
- Use the main visitor entrance and follow the posted route for both garden and museum access-check the house's calendar for lectures and special garden events, which can change normal access patterns.
