The Friends of Georgia State Parks and Historic Sites has dubbed it Your State Parks Day, and urges park guests to sign up as volunteers.
Special events will be held at national and state parks across the country. In Georgia, they include volunteer projects, family outings and kids’ events at parks across the state.
Parking is normally $5 at state parks, and admission ranges from $2.50 to $10 at state historic sites. On Saturday at most parks, parking and admission are free.
South Carolina’s state parks and historic sites near Augusta are not participating, a spokeswoman said.
National Public Lands Day began in 1994 as an opportunity to get volunteers out on trails, removing trash, planting trees and other work to maintain natural and cultural resources. That first year, 700 volunteers participated at three sites across the country. Last year, more than 170,000 volunteers worked at upwards of 2,000 parks and historic sites.
