Stoney Glen Market in North Potomac: Your Saturday Guide

For years, the intersection of Travilah and Glen Roads was a place you passed through on the way somewhere else. A corner store with a loyal following, a shopping center that residents recognized more by its enormous white oak than by its tenants, and a wooded lot most people did not realize was public land. Three pieces, used separately.

That changed a few weeks ago. A new open-air market opened in the Potomac Oak Shopping Center parking lot, and for the first time the corner has a reason to hold a resident's whole morning, not just a five-minute errand. This post is about what is actually there now, why the three pieces fit together better than they used to, and how to build a Saturday around them without leaving a half-mile radius.

The Market That Just Landed

Stoney Glen Market held its grand opening weekend on July 11 and 12, 2026, at 12944 Travilah Rd. in Potomac, from 8am to 2pm, and it now operates every Saturday and Sunday from April through mid-December. It ran a quiet soft opening through the early summer before that, so most neighbors are still finding it for the first time.

The sourcing story is worth understanding before you go. Most of the fresh produce and eggs come directly from Massum Eyrie Farm in St. Mary's County, which is owned by the Montgomery County family behind Stoney Glen Market, and organizers say the focus is on providing customers with fresh, organic, chemical-free products while supporting local agriculture and producers. That single-farm anchor is different from the rotating-vendor model at markets like Potomac Village on Glen Road, and it shapes what you find on the tables.

What is actually for sale right now, per the organizers:

• Fresh produce and eggs from the family farm
• Local honey and handcrafted bread
• Chocolate milk and strawberry milk
• Flowers, seasonal offerings, small-batch beverages
• A growing roster of artisan bakers and makers as the season progresses

Organizers say they plan to continue expanding the vendor lineup as the market grows throughout the season, so the table count in August will look different from what opening weekend crowds saw.

The Tree You've Driven Past A Thousand Times

The market sits at the base of one of the most impressive trees in the state, and if you have lived here longer than a year you have almost certainly walked past it without stopping to read the plaque.

The Travilah Oak is one of the largest trees in the state of Maryland. It is an expansive white oak with a circumference of over 18 feet, a height of 78 feet, and a crown that stretches 108 feet. Believed to be over 285 years old, the towering tree is flanked by a plaque that trumpets its historical significance as having stood since before the signing of the Constitution.

There is more history in that crown than most residents realize. The celebrated tree, which escaped destruction at the hands of a construction project in 1997, is named for the first postmaster of the area where it resides, Travilah Cleggett, and each year a festival surrounding the heritage of the local community is held on the tree's birthday.

The practical upshot: the market is not sitting in a generic strip-mall parking lot. It is sitting at the foot of a specimen tree that predates the country, in a shopping center whose LLC is literally named for it. That matters because the shade under a 108-foot crown is a functional part of how the market feels between 10am and noon on a warm Saturday.

The Park Most Neighbors Still Don't Use

Cross Glen Road and you are at Greenbriar Local Park. It is one of the newer additions to the county's inventory in this pocket, and it is quietly the missing piece that makes the whole corner work.

The North Potomac Citizens Association lists Greenbriar Local Park at 12525 Glen Rd., Travilah, MD 20854 as one of the local county parks serving the area, alongside Aberdeen, Big Pines, Dufief, and Quince Orchard Knolls. The 25.1-acre park is an open and partially wooded area near the intersection of Travilah Road and Glen Road, providing natural open space for the enjoyment of residents and passersby. It is walkable from the market lot, which is not something you can say about the parks tucked deeper into the subdivisions off Quince Orchard Road.

Most neighbors I talk to know Aberdeen or Dufief far better than Greenbriar. Now that there is a reason to be at the corner every weekend morning, that will probably shift.

A Saturday Loop That Didn't Exist Last Summer

Here is a rhythm that only became possible in July. It assumes you drive in from a Quince Orchard or Dufief address, park once, and stay put.

1. Arrive at Potomac Oak Center by 8:30am. The market opens at 8, and the produce table is fullest in the first hour.
2. Shop Stoney Glen first, then walk your bags to the car so you are not carrying eggs around the tree.
3. Read the plaque at the Travilah Oak. Yes, actually read it. The 1997 story alone is worth the two minutes.
4. Walk the perimeter of Greenbriar Local Park across Glen Road. Twenty five acres is enough for a real loop, not a token stroll.
5. Come back to Potomac Oak Mart at 12960 Travilah Rd for a sandwich or a coffee before you head home.

That last stop is not a formality. The family-owned corner shop is a mix of neighborhood regulars grabbing beer and contractors stopping by for lunch, and the Philly cheesesteak with pepper jack cheese is one to ask for by name. It is the kind of anchor tenant that shopping centers on the edge of a suburb rarely still have, and it pairs oddly well with a farmers market bag in your other hand.

The Corner At A Glance

Why This Corner, Why Now

North Potomac's shopping infrastructure is mostly built around the edges of the community. The North Potomac Citizens Association identifies four shopping centers around the edges of North Potomac: Potomac Oak Center, The Shops at Potomac Valley, Travilah Square, and Traville Village Center. Of those four, Potomac Oak has always been the smallest and the most character-driven, largely because of the oak and the mom-and-pop mart. It has never been the place you drove to for a weekend outing.

A market changes that equation. Not because a farmers market is exotic in Montgomery County. It is not. The Potomac Village Farmers Market at Potomac United Methodist Church runs Thursdays 3 to 6:30 p.m. from May 7 to Nov. 26, 2026, and half a dozen others sit within a fifteen-minute drive. What Stoney Glen adds is a weekend market on the North Potomac side of the divide, at a corner with a tree, a park, and a lunch spot already in place. The pieces existed. Now they connect.

The other detail worth naming: this is a family running a farm in St. Mary's County and a market in Montgomery County. That is a two-hour supply chain, and it shows up in what is on the tables. If you are used to markets where every stand is a different vendor, Stoney Glen will feel more curated and a little sparser. Give it a season. The vendor lineup is expected to keep expanding through the fall.

Bring The Bag You Actually Use

The best thing about a new anchor in a neighborhood you already live in is that you get to shape what it becomes. Show up in August, show up in October when the crowns of the oak start to turn, show up in December on the last weekend before the market closes for the season. The corner rewards regulars.

If you are thinking about the bigger picture — whether that means finding the right house near a corner like this one, or getting your current home ready for a market that has changed in ways worth talking through — Valerie Harnois knows this stretch of North Potomac by the intersection, not by the zip code. Let's connect.
