Earth Day Fairfax will be an unforgettable day of fun, education and community. The 2026 event will take place on Saturday, April 25 from 10 a.m. to 4 p.m. at Lake Fairfax Park in Reston. Earth Day Fairfax is the county’s largest Earth Day celebration, and we are asking for your help. Join us as an Earth Day Fairfax volunteer.

This special event will feature games, entertainment, exhibits, workshops, vendors and activities to help increase our understanding of and appreciation for the world around us. We expect around 7,000 people from across Fairfax County to attend. Volunteers are needed to fill shifts throughout the day in a variety of capacities, including:

• Set-up attendants
• Check-in greeters 
• Nature and recreation activity attendants 
• Guest assistance 

 This is an ideal service opportunity for students seeking service hours or community members looking to give back. Through a variety of service activities, volunteers will impact the community and the environment while having fun throughout the day.

All volunteers must be 15 years old or older. Multiple shifts are available to accommodate scheduling needs. For additional details about individual volunteer opportunities and to sign up, visit the Volunteer Fairfax website.
