Recreate Responsibly

When recreating, please follow local area health orders, practice Leave No Trace principles, and avoid crowding and high-risk outdoor activities.

The CDC has offered guidance to help people recreating in parks and open spaces to prevent the spread of infectious diseases. We will continue to monitor all park functions to ensure that visitors adhere to CDC guidance for mitigating risks associated with the transmission of COVID-19 and take any additional steps necessary to protect public health.
