Help Keep Yosemite Beautiful!
Become a volunteer!

Join the Habitat Protectors of Yosemite (HaPY) at our weekly drop-in program! Volunteers help protect and restore Yosemite's valuable plant and wildlife habitat in Yosemite Valley and other high value habitat areas in Yosemite National Park. Visit some of the most scenic areas in the park and help Resources Management & Science staff manage the park's precious resources. Plan to get dirty working on a variety of resource management projects such as manually removing invasive plant species or maintaining native plantings. Get involved and meet new people. Take an active role in managing your national park. Volunteer hours count towards earning the America the Beautiful volunteer pass.
