JACKSONVILLE, Fla. - If you're looking for something to do this weekend, try visiting a National Park. Turns out, it's nearing the end of National Park Week and the National Park Service wants to help you celebrate by offering free admission to its parks this weekend.

Locally, that means you can go visit Castillo de San Marcos National Monument in St. Augustine at no cost Saturday, April 22 to Sunday, April 23. Normally, it costs visitors $10 to enter.

There is another national park in Jacksonville: Fort Caroline National Memorial. According to its website, it is free to enter throughout the year.
