Hidden in the heart of Georgetown, Dumbarton Oaks feels like stepping into another world. The historic estate is best known for its sprawling gardens — terraced lawns, winding brick paths, and tucked-away fountains that shift with the seasons. Inside, the museum houses Byzantine and Pre-Columbian art, but it’s the outdoor spaces that steal the spotlight, offering a mix of elegance and quiet escape. Whether you’re wandering through rose gardens, catching the fall colors, or just looking for a peaceful retreat, Dumbarton Oaks is one of D.C.’s most enchanting corners.
