Drop-in Volunteering and Special Events

Conifer Removal Project


Throughout the year, we have several special events such as Junior Ranger Day, Earth Day (both in April), Apple Picking Day (mid August), and Yosemite Facelift (late September), where volunteers can just show up, no application needed. We list these events on this website when we know the dates for each year.

For all special events and drop-in days, the park asks participants to wear long pants and closed-toe shoes, appropriate gear for the weather, and bring sun protection, water, and snacks. The park provides tools and protective equipment.

All participants must sign a volunteer agreement [42 kb DOCX]. If you'd like to fill out the in advance, this form will be posted with each special event or drop-in project as they are planned (you can also sign one on the day of the project on-site). Guardians must sign the form for participants under the age of 18.

Drop-In Volunteering

Help keep Yosemite beautiful! The Volunteer Drop-In Program is a family-friendly way you can take an active role in protecting and preserving our natural resources. Whether you're new to the park or returning, come have new experiences while removing invasive species, collecting seeds, picking up litter, and more.

Special Events

Martin Luther King Jr. Day of Service: January

Martin Luther King Jr. Day of Service calls on everyday people each year to make the third Monday in January "a day on, not a day off."

Earth Day: April 21, 2018

Yosemite has a park-wide celebration of Earth Day, usually on the Saturday on or before Earth Day. The park usually schedules a volunteer project on both the Earth Day celebration date as well as Earth Day itself. Projects include ecological restoration and litter cleanup, and are appropriate for all ages. In the past projects have been two to three hours in duration.

National Park Week: April 21-29, 2018

While there may not be specific National Park Week projects, Junior Ranger Day and Earth Day usually fall during National Park Week.

Junior Ranger Day: April 21, 2018

Volunteer to earn your Junior Ranger Badge! As part of the Junior Ranger Day celebration, volunteers can do a restoration or litter project. Junior Ranger Day will be celebrated on Saturday, April 23, 2016 in conjunction with Earth Day.

Apple Picking Day: August

Historic apple orchards in Yosemite Valley attract bears, leading them to eat non-native foods while increasing human-bear conflicts in parking areas and campgrounds near the orchards. To help decrease the impact of the orchards, volunteers are invited to pick apples, removing the temptations for the bears.

Yosemite Facelift (and National Public Lands Day): last week in September (September 25-30, 2018)

In partnership with the Yosemite Climbing Association, the National Park Service puts on this five-day event each September, Wednesday through Sunday including the last Saturday of the month. In 2012 over 1,200 volunteers cleaned up 20,000 pounds of debris from the park. To learn more, visit our partners at the Yosemite Climbing Association.
