Many of Alabama's state parks will offer free admission on Friday. The park system is using the 200th day of the year to celebrate the state's 200th birthday.
Twenty-one different parks span the state and feature the diversity of Alabama's landscape.
"We offer a huge range of geographical features," said Kevin Jones, the marketing specialists for Alabama State Parks. "You go from the beaches at Gulf State Park, and then you travel north through north Alabama and you're getting to the foothills of the Appalachians."
Most of the participating parks will also allow free parking and discounted overnight accommodations.
Each year around 3 million guests visit Alabama state parks. Jones said these visitors make more than a $300 million impact on Alabama's economy.
