Thanks to National Get Outdoors Day, no permit is required Saturday at Minnesota state parks.

Usually, state park visitors must pay $5 for a day pass or $25 for a year-round vehicle pass.

In addition to free admission, events are planned at parks throughout the state. Most are free, but some require registration, which is available on the state Department of Natural Resources website.
