Fourth-graders and their families can visit the national parks and federal recreation areas of their choice across the country for free for an entire year.

The National Park Service is offering that opportunity through an online program called “Every Kid in a Park.”

To receive the free pass for national parks, youngsters can visit the website at www.everykidinapark.gov.

They will be directed to complete an online activity before printing their pass.

It is valid through August 2016, according to the website.

The initiative launched by President Obama is designed to “connect fourth-graders with the great outdoors and inspire them to become future environmental stewards,” according to a news release from Petersburg National Battlefield.

The program is a part of the National Park Service’s centen- nial celebration, it further states.

National parks in the area include Richmond National Battlefield Park, the Maggie L. Walker National Historic Site, Petersburg National Battlefield, Colonial National Historical Park and Yorktown Battlefield.
