Things to Do in Arlington VA This Weekend: Clarendon Day & More

Arlington already had one big weekend this month. On September 12, Gateway Park filled up for the 34th Rosslyn Jazz Fest, Arlington's largest free outdoor music festival, with Grammy-nominated Plena Libre headlining a lineup that also included Sally Baby's Silver Dollars and Dogo du Togo & The Alagaa Beat Band. If you assumed the county's calendar would ease up after that, look again. September has already brought a three-day Oktoberfest in Courthouse and the start of a five-date brewery rotation in Shirlington; still ahead are the county's biggest street festival and a grocery store reopening that people have been tracking since before it had a name attached to it.

Two of those land back to back. Sprouts Farmers Market holds its grand opening at 3115 Langston Blvd on Friday, September 25. Clarendon Day takes over eight blocks around the Clarendon Metro the very next morning, Saturday, September 26. Nobody coordinated that. One is a retail lease finally closing after roughly two and a half years of an empty storefront. The other is an annual tradition that predates the vacancy by decades. The fact that they land one day apart is a coincidence of timing, but it changes how the next two weekends should actually be planned if you live here.

The Grocery Store Everyone Has Been Watching

The Giant at Lyon Village Shopping Center closed in March 2024 after serving as the plaza's anchor for 60 years. That is not a small gap. For a shopping center built around walk-up convenience, losing the grocery store for two and a half years meant the daily-errand loop that had defined the corner of Langston Boulevard and Spout Run Parkway simply stopped working the way it always had. The Italian Store and CVS stayed open the whole time and kept the plaza from going dark, but neither one replaces a full grocery store.

Sprouts filed its permit to convert the space in April 2025 and confirmed the Arlington location a month later. A "coming soon" banner went up in March 2026, and by July the company had locked in a September opening date. The grand opening now runs Friday, September 25 through Sunday, September 27, with free tote bags, food samples, and discounts for anyone who stops in. ARLnow quoted Sprouts describing its shopping experience this way:

an experience rooted in freshness, quality and wellness

That description lines up with what the chain has built at its other Northern Virginia locations in Herndon, Manassas, and Leesburg. An application to sell beer and wine at the address is still pending, which is worth watching if you care whether the plaza fully returns to its old function or lands just short of it.

The Morning After, the Whole Neighborhood Shows Up

Clarendon Day runs from 11 a.m. to 6 p.m. on Saturday, September 26, centered on the Clarendon Metro station at 3100 Wilson Blvd. It is Arlington's largest street festival, with more than 150 local vendors, live music on multiple stages, a beer and wine garden, and a dedicated kids zone. Attendance regularly tops 20,000. Admission is free, and the event happens rain or shine.

Here is where the timing actually matters for anyone who lives nearby. Clarendon Day brings street closures and a wall of foot traffic to a corridor that sits about two Metro stops from the new Sprouts. If you were planning to swing by Sprouts on Saturday morning to see what the fuss is about, you will be doing it in the same window that Clarendon starts filling up with festival traffic. The practical move is to treat Friday, not Saturday, as your grocery day this particular week, since the grand opening runs all three days anyway.

Oktoberfest Doesn't Pick One Saturday; It Spans More Than Two Weeks

Unlike Clarendon Day, which has one date and one location, Arlington's Oktoberfest events this year span multiple neighborhoods from September 18 through October 3. ARLnow's roundup lays out the schedule:

• Friday, September 18 — Astro Beer Hall in Shirlington kicked off its five-date Oktoberfest rotation on its newly reopened 100-seat patio, pouring Paulaner first. Courthaus Social in Courthouse also opened its three-day festival the same night.
• Saturday, September 19 — Astro Beer Hall poured Samuel Adams. Over in Rosslyn, UPSIDE on Moore hosted a free, all-ages Oktoberfest from 11 a.m. to 9 p.m., with an Oktoberfest Märzen from Silver Branch Brewing on draft and a live band from 5 to 8 p.m.
• Sunday, September 20 — Courthaus Social wrapped its three-day run.
• Thursday, September 24 — Astro Beer Hall's rotation continues with DC Brau.
• Saturday, September 26 — Astro Beer Hall pours 3 Floyds the same day Bronson Bierhall in Ballston runs a ceremonial cask tapping, a stein-holding contest, and a "das boot" chugging competition using a boot-shaped glass.
• Saturday, October 3 — Astro Beer Hall closes its rotation with Port City.

Every one of the Astro Beer Hall dates runs 5 to 7 p.m. and includes an $11 beer-and-pretzel combo, with a 10 percent discount for anyone who shows up in a dirndl or lederhosen. Admission across nearly all of these events is free.

The spread-out format means there is no single "Oktoberfest Saturday" to circle on the calendar the way there is for Clarendon Day. It also means the beer crawl and the street festival share one date, while the other Oktoberfest events fall before and after Clarendon Day.

Planning the Remaining Events Without Doubling Back

Given how the dates fall, here's a sequence for the remaining events that covers the ground without retracing steps:

1. Thursday, September 24 — A quieter midweek stop at Astro for DC Brau, easy to fold into a weeknight.
2. Friday, September 25 — Swing by Sprouts for the grand opening before the Clarendon Day crowds build. Grab the tote bag and the food samples while the aisles are still walkable.
3. Saturday, September 26 — Start in Ballston for Bronson Bierhall's cask tapping, then take the Orange Line two stops to Clarendon Day. Astro's 3 Floyds pour that evening in Shirlington is a reasonable close if you're not ready to call it a day.

None of this requires a car. The Orange and Silver Line corridor connects Ballston, Clarendon, Courthouse, and Rosslyn directly, which is exactly why a stretch this packed is manageable on foot and Metro rather than a scheduling headache.

Why These Dates Matter

The Sprouts opening and Clarendon Day fall on consecutive days, while the Astro Beer Hall Oktoberfest rotation runs from September 18 through October 3. When a neighborhood's commercial recovery, its biggest annual gathering, and its beer culture overlap, it says something about how compressed Arlington's fall calendar has become. This year, the events are clustered across late September and early October.

If you're the kind of person who tracks these overlaps because you already live here and plan your Saturdays around them, that's the whole point of this piece. If you're the kind of person who's been watching what happens to a corner like Langston and Spout Run once its anchor tenant finally returns, because you're curious what that means for the block you're already on, The Seward Group spends a lot of time paying attention to exactly this kind of neighborhood detail. Schedule a Concierge Consultation whenever you're ready to talk through what any of it means for you.
