Trailside Earth Day Celebration — April 25

Trailside Museums & Zoo in Bear Mountain will hold its Earth Day Celebration on Saturday, April 25, from 11 a.m. to 3 p.m. at 10 Bear Mountain State Park. (parks.ny.gov) The New York State Parks listing says the event will include crafts, games, and live animal presentations, with activities such as making seed balls, nature necklaces, and a nature-themed matching game. The museum’s own events page lists the same April 25 program and hours. (parks.ny.gov) (trailsidemuseumsandzoo.org) Admission to Trailside Museums & Zoo is free, and the state parks listing says no pre-registration is required for the celebration. Visitors driving into Bear Mountain State Park should expect a $10 per-vehicle parking fee. (parks.ny.gov) The event lands three days after Earth Day 2026, which fell on Wednesday, April 22. Earthday.org says this year’s global theme is “Our Power, Our Planet.” (earthday.org) Trailside sits inside Bear Mountain State Park, a heavily visited Hudson Valley park that combines trails, a small zoo, and museum exhibits focused on local wildlife and natural history. The April 25 program packages that setting into a single afternoon aimed at families and casual visitors rather than a ticketed festival crowd. (trailsidemuseumsandzoo.org) (parks.ny.gov) The Hudson Valley News calendar included the celebration in its April 20-26 roundup and linked readers to a volunteer sign-up alongside the event listing. That places the program in the region’s broader week of Earth Day cleanups, fairs, and outdoor programs.
