OC Parks Introduces New Parking Passes

OC Parks is pleased to introduce new parking passes that will allow visitors to use a single card to park at all County regional and wilderness parks and/or beaches.

The new “smart cards” replace the entry cards and stickers that were previously used for annual parking. Unlike the previous OC Parks passes, which were fixed to a calendar year (January through December), these smart cards are valid for 12 months from issue date and can be renewed annually. Moreover, for wilderness and beach locations which previously required a sticker affixed to a visitor’s windshield, these passes can be used with any vehicle. The price for the new cards remains the same as 2014.
