Even with its peeling white paint, Cabin 5 feels like home to Golda Shore. For two decades, the 96-year-old has left Florida each summer for a “Trip to Yiddishland,” a weeklong immersion in Yiddish language and culture.

Ms. Shore is one of 230 people, ages six months to 100, participating in this summer’s retreat about 70 miles north of New York City. Early risers can stretch into sunrise with “yoga and kvetch,” while the more dramatic attendees can dive into workshops on Yiddish theater and song. There are also six levels of Yiddish-language classes, from beginner to advanced.

“I look forward to it every year. I wouldn’t dream of missing it. I’ve been told I’m the first to register. Each time I think, ‘This will be my last,’ so when I return, I’m delighted,” Ms. Shore says

The daughter of Eastern European Jewish immigrants, Ms. Shore grew up in a Yiddish speaking household. “When I shopped with my mother, everyone spoke Yiddish – the deli, the appetizing shop, the kosher butcher. It was like a little shtetl.” For one week each summer, Ms. Shore is once again surrounded by the rhythms of her first language.

Now in its 20th year, Yiddishland is run by the Workers Circle, or Der Arbeter Ring. Founded 125 years ago by Yiddish-speaking immigrants, the organization has long blended labor activism, mutual aid, and cultural preservation. Today, Yiddishland does more than keep the language alive after the Holocaust. It sparks a new generation of enthusiasts.
