The Smithsonian’s Enid A. Haupt Garden is a 4.2-acre public garden tucked behind the Smithsonian Castle on the south side of the National Mall. It opened in 1987 and brings together three small gardens in one space: a central Parterre lawn surrounded by saucer magnolia trees, the Moongate Garden on the west, and the Fountain Garden on the east.
Washington DC magnolias typically bloom a few weeks before the cherry blossoms, which makes the Haupt Garden a perfect stop if you arrive too early for cherry blossom peak bloom.
Visitor note for 2026: The Smithsonian Castle itself is currently closed for a multi-year renovation, but the Haupt Garden has remained open throughout the South Mall Campus project. The Castle is set to temporarily reopen May 22 to September 7, 2026 for the “American Aspirations” exhibition celebrating America’s 250th birthday.
The Enid A. Haupt Garden has a couple of smaller gardens on each of the property. Luckily the gardens are small enough to see everything in one visit, typically you can walk around everything in under 20 minutes.
Things to Know When Visiting the Haupt Garden
- The Haupt Garden is open daily from dawn to dusk and is closed only on December 25. Gates close overnight, so sunrise visits in the spring should be fine but anything after dusk is locked up.
- Admission is free. Like all Smithsonian gardens, there is no entrance fee or ticket required.
- Tripods are allowed throughout the garden grounds, which is unusual for the Smithsonian complex.
- Peak magnolia bloom is typically late March, a few weeks before the National Mall’s cherry blossom peak.
The Central Parterre
The biggest section of the Haupt Garden is the central Parterre. It is a formal embroidery-style garden behind the Castle, with low boxwood hedges, seasonal flower beds, and the saucer magnolia trees that draw most of the photographers here in late March. The Parterre rotates plantings through the year (tulips in spring, summer annuals later), and the views back toward the Smithsonian Castle from this section are some of the best on the south side of the Mall.
The Moongate Garden
On the west side of the Haupt Garden is the Moongate Garden, a small Chinese-inspired space with two 9-foot pink granite moon gates flanking a shallow pool paved with half-round granite. The pool catches the reflection of the Smithsonian Castle on still days, which is one of my favorite angles in the whole garden.
The Fountain Garden
On the east side is the Fountain Garden, a Moorish-style geometric garden inspired by the Court of the Lions at the Alhambra in Granada, Spain. A central jet fountain sits at the intersection of four narrow water channels, which represent the four rivers of paradise described in the Koran. The Fountain Garden was designed to complement the National Museum of African Art and Sackler Gallery that frame the south end of the property.
Getting to Enid A. Haupt Garden
The Haupt Garden is on the south (back) side of the Smithsonian Castle, between the Castle and Independence Avenue SW. The Castle itself is hard to miss from the National Mall.
The easiest way to get to the gardens is to take the DC Metro to the Smithsonian stop (Orange/Blue Lines). Once you get off the Smithsonian stop you’re only a couple of blocks from the Smithsonian Castle and garden grounds.
Additionally, you can pay a meter to park directly on the mall in front of the Smithsonian or on the opposite side of the castle on Independence Ave SW. During peak times parking can be hard to find in these busy areas but if you come for sunrise it should be easy to find a spot.
