An eco-festival of local solutions!

Presented in partnership with the O'Hara Nature Center and the Irvington Recreation and Parks Department, EarthIrvington is a two-day environmental festival featuring musical performances, film screenings and forums, sustainable eats, and outdoor activities for the whole family. This celebration of nature asks our community to think globally and act locally in order to protect the environment.

The fun begins on Friday, October 1 with locavore fare from nearby eateries and an open-air screening of Wasted! The Story of Food Waste (2017) from Executive Producer Anthony Bourdain (who also narrates) following a Q&A with the documentary’s director, Nari Kye, alongside a panel of leaders from Westchester County organizations whose missions reflect a commitment to sustainability.

The festivities continue on Saturday, October 2 with guided tours of the Nature Center’s 400+ acres of forested trails, “Ask the Expert” tables, hands-on workshops, and a righteously irreverent performance from Reverend Billy and the Stop Shopping Choir, a storied group of self-identified urban activists who use theater of protest, spectacle, and song to fight for climate justice. Explore the full lineup below!

This festival will be held outdoors at the O’Hara Nature Center in Irvington on October 1 and 2. Rain date is October 3. On-site parking is available, and carpooling is encouraged. Questions about accessibility at this event? Email
