Which park passes should you buy if you are a family living in Orange County, CA? It’s a question that plagues parents who wants to play outside more, but don’t have the time to research every possible outing or admission price.

I will try to make it easy for you. Your choices range from:

• Spend $0 – see FREE PLAY.
• Spend $55/year – OCParks.com County Regional and Wilderness Parks Annual Pass OR County Beach Parking Pass with Pay & Display Machines. (Purchase online or at some park offices)
• Spend $80/year – OCParks.com All County Parks and Beaches Parking Pass. (Purchase online or at some park offices)
• Spend $195/year – Access to almost all CA state parks and beaches in Orange County with CA Explorer Vehicle Day Use Pass.
• Spend $180/year (or less for Oct-Dec only) – City of Newport Beach Annual Parking Permit.
• Spend $50/year (resident) or $100/year (non-resident) – City of San Clemente Metered Parking Permits
• Spend $150/year – City of Huntington Beach beach parking.

Also, look for Senior parking permits which can be as much as half the price – if you are a grandparent looking for places to go with the grandkids.

Personal Note: Out of all these options I always by an $80/year OCParks.com All County Parks and Beaches Parking Pass AND a CA state parks pass at $195/year. But visiting and reporting on parks is a big part of my life! After chatting with other local park lovers, I found that those who live inland like the county park pass – and those near the beach opt for the state parks pass. Another strategy is to alternate your investment every year so that you get your money’s worth out of the state park pass one year and the county pass the next year. I just included the Newport Beach, San Clemente, and Huntington Beach info for those of you who might live in or near those towns.
