Glenstone is a contemporary art museum on more than 200 acres of woodland and meadow in Potomac, Maryland, about a 30 minute drive from Washington DC. Admission is free, but you need a ticket, and they go fast.
It is one of the most striking places to visit in the DC area, as much for the buildings and the landscape as for the art. This guide covers how to get tickets, what the rules are (including the photography rules, which catch a lot of people out), what to see, and my own photos from a very foggy visit.
Know Before You Go
- Free, but ticketed. Tickets are released on the 1st of each month at 10 a.m. for that month and the next.
- Open Thursday through Sunday, 10 a.m. to 5 p.m. Closed Monday through Wednesday.
- Visitors must be 12 or older. This is a real restriction, not a suggestion, so it is not a stop for young kids.

- Parking is free and on site.

Planning Your Visit
Hours
Glenstone is open Thursday through Sunday from 10 a.m. to 5 p.m. and closed Monday through Wednesday. The gates open at 9:45 a.m. and the last admission is at 3:15 p.m., so a late-afternoon arrival will not get you in.
In 2026 there are extended hours on Saturdays from May 23 through September 5, when the museum stays open until 8 p.m. with last admission at 6:15 p.m. The trails close at 5 p.m. or sunset.
Tickets and reservations
Admission is always free, but you cannot just show up. Timed tickets are required and they are released on the 1st of every month at 10 a.m., covering that month and the following month. Visits are scheduled on the half hour between 10 a.m. and 3 p.m.
Tickets for weekends go quickly, so set a reminder for the 1st if you want a Saturday or Sunday slot. Weekday (Thursday and Friday) times tend to last longer. Glenstone also runs a guaranteed entry program for educators and veterans.
Getting there and parking
The address is 12100 Glen Road, Potomac, MD 20854. Parking is free and on site, which is a nice change from parking anywhere near the National Mall. There is no Metro station within walking distance, so driving or a rideshare is realistically the only way in.
Age policy
Visitors must be 12 years or older. It is worth repeating because it surprises families who plan a day trip and turn up with younger kids.
Food and how long to stay
There is a cafe open from 10:30 a.m. to 4 p.m. and a patio open until 4:30 p.m. The bookstore is open 10 a.m. to 5 p.m. and does not require a ticket.
Give yourself at least three hours. Between the Pavilions, the outdoor sculptures, and the walking trails, it is easy to spend most of a day, and rushing it defeats the point of the place.
Photography Rules at Glenstone
This is the part worth reading twice if you are bringing a camera.
- No photography inside the buildings. The galleries are strictly no-camera, phones included.
- Outdoors you can shoot for personal use. The grounds, the architecture from outside, and the outdoor sculptures are all fair game.
- No tripods, no drones, no selfie sticks, and no auxiliary lighting. So handheld only, which is worth knowing if you were planning long exposures.
For most people that means a phone or a single camera body and one lens. Since you are handholding everything, a lens you can shoot wide open is more useful here than a tripod-dependent setup.
What to See at Glenstone
Glenstone was founded by Mitchell and Emily Wei Rales and opened in 2006 with a gallery designed by Charles Gwathmey. The site changed completely in October 2018 when the Pavilions, designed by architect Thomas Phifer, opened and multiplied the gallery space several times over. The collection runs to roughly 1,300 post-World War II works.
The Pavilions and the Water Court
The Pavilions are a ring of concrete and stone-block rooms built around a central Water Court, an open pool planted with water grasses that you see through floor-to-ceiling glass as you move between galleries. It is the signature space of the museum and the thing most people remember.
Outdoor sculptures
The grounds are the other half of the visit, and several of the outdoor works have their own viewing windows, which is easy to miss when you plan your day:
- Jeff Koons, Split-Rocker (2000) is the 37-foot flowering sculpture planted with tens of thousands of flowers, half pony and half dinosaur. It is only in bloom from May to October, so a winter visit will not include it.
- Richard Serra, Four Rounds: Equal Weight, Unequal Measure (2017) has its own building, open daily 10:30 a.m. to 4:30 p.m., weather permitting.
- Andy Goldsworthy, Clay Houses (Boulder-Room-Holes) (2007) is only open 12:30 to 1:30 p.m. and 2 to 3 p.m. Plan around those windows or you will walk right past it.
- Felix Gonzalez-Torres, “Untitled” (1992 to 1995) is covered from fall until spring and uncovered once the freezing weather passes.
There is also a woodland trail with uneven terrain, so wear shoes you can actually walk in, and an Environmental Center that opened in 2019.
My Experience at Glenstone
Upon arriving at Glenstone, I was immediately struck by the serene and peaceful atmosphere that envelops the entire museum. Nestled amidst lush green landscapes and rolling hills, the art museum feels like a hidden oasis. My visit was during a foggy day which really added to the atmosphere.
I was impressed with the museum’s stunning architecture. The museum’s buildings are designed to seamlessly blend with the natural surroundings, creating a harmonious connection between art and nature. The use of glass walls allows natural light to flood the galleries, creating a truly immersive experience.
Glenstone boasts an impressive collection of contemporary art, featuring works by renowned artists from around the world. From monumental sculptures to thought-provoking installations, each artwork tells a unique story, leaving a lasting impact on visitors.
One of the highlights of visiting Glenstone is the opportunity to explore its expansive outdoor grounds. With winding woodland trails that lead through serene woodlands and picturesque meadows, nature enthusiasts are in for a treat. The sculptures scattered throughout the landscape further enhance the experience, blurring the boundaries between art and nature.
In the center of the Glenstone museum is the water court. This tranquil space, has a beautiful water feature and is quite peaceful. It’s the perfect spot to sit back, relax, and take in the beauty of the museum.
