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, as well as on volunteer.gov.
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.
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.
