Earth Day at Natural History Museum LA

Los Angeles’ Natural History Museum is spending Sunday, April 19, on an Earth Day festival built around hands-on activities, outdoor programs and family museum visits. (nhm.org) The event runs from 9:30 a.m. to 5 p.m. at the Natural History Museum of Los Angeles County in Exposition Park, and admission is free for members or included with paid museum entry. (nhm.org) (expositionpark.ca.gov) Museum listings say the program includes time in the Nature Gardens, outdoor performances, art and science activities, and access to exhibitions including Dinosaur Hall, Gem & Mineral Hall and the Mammal Halls. (nhm.org) (kcrw.com) The museum is also tying the day to Los Angeles ecology, with activities framed around local nature and environmental change rather than a single stage show or lecture. NHM’s event page says visitors can “discover L.A. underwater,” a reference to the region’s prehistoric past beneath the Pacific. (nhm.org) (discoverlosangeles.com) That format fits the museum’s larger public-facing nature program. NHM’s homepage bills the annual Earth Day festival as a day with live music, hands-on activities, scientists and films, folding environmental education into a standard museum outing. (nhm.org) This year’s festival also includes “Green Screen: Our Planet on Film” screenings in the Commons Theater, according to NHM and outside event listings. Beverly Press reported the 2026 edition also features LEGO Build the Change and opportunities to meet scientists, educators and environmental groups. (nhm.org) (beverlypress.com) We Like L.A. highlighted the festival in its April 17-19 weekend guide and described the draw in simpler terms: birding, nature photography and other drop-in activities for a Sunday museum crowd. (welikela.com) For families deciding what to do today, the pitch is straightforward: one ticket gets a full museum day plus Earth Day programming spread across galleries, gardens and theater spaces until 5 p.m. (nhm.org)
