Arlington residents have two exciting community events to look forward to this fall, with the City of Arlington officially announcing both the return of the West Main Arts Festival and the free W.A.T.E.R. Festival at River Legacy — giving locals plenty of reasons to get outside and celebrate.

First up is River Legacy’s W.A.T.E.R. Festival, set for Friday, September 12, 2026. Best of all, admission is completely free. The festival is hosted at River Legacy, one of Arlington’s most treasured natural spaces, and promises a fun, family-friendly day centered on the environment and the community that loves it. Whether you’re a longtime River Legacy fan or a first-time visitor, this is a wonderful opportunity to enjoy the outdoors without spending a dime.

Then, just one week later, downtown Arlington comes alive with the return of the West Main Arts Festival on Saturday, September 19, 2026. The festival brings art, culture, and community spirit straight to the heart of the city, making it a highlight of Arlington’s fall calendar. Downtown Arlington’s West Main corridor serves as a vibrant backdrop for this celebration of local creativity and community connection.

Adding even more excitement to the season, Arlington’s First Thursdays events in September will carry a special theme — spotlighting the city’s 150th anniversary. It’s a milestone worth celebrating, and the monthly First Thursdays gatherings will give residents a chance to reflect on Arlington’s rich history while enjoying the community atmosphere that makes the city so special.

Together, these upcoming events paint a picture of a city that knows how to bring its people together. From free outdoor festivals along the river to arts celebrations in the heart of downtown and a sesquicentennial salute, Arlington’s fall lineup is shaping up to be one for the books. Mark your calendars — September is going to be a great month to be an Arlington resident.
