April 16 to 24 is National Park Week.
Practically, this means free admissions to all national parks.
If you go today, Saturday, April 16, your child can earn a junior ranger badge.
April 22 is Earth Day. You can celebrate by helping out at a national park.
April 24 is Park Rx Day, a new annual day to promote how parks can improve health and well-being. Apparently lots of family-friendly activities are being planned.
