Getting into state park is getting more expensive but if you plan ahead, you can get in for free.

• California State Parks Library Pass Free – A new pilot collaboration between State Parks and California State Libraries will provide free passes to every public library throughout the state. Library patrons can check these out and use them for free vehicle day-use access to parks across the state. 
  If you don’t have a library card, visit your local library to get one. The library card and park pass are free! In partnership with the First Partner’s Office and the California State Library, State Parks is providing free vehicle day-use entry to over 200 participating state park units operated by State Parks for check out to library-card holders. The California State Library Parks Pass is valid for entry of one passenger vehicle with capacity of nine people or less or one highway licensed motorcycle.
• California State Parks Adventure Pass Free – This new pass provides free entry for fourth graders and their families at 19 select state parks throughout the state.
• California State Parks Limited Use Golden Bear Pass $20 – not quite free but cheap & valid for one year, this pass is for individuals 62 years or older and provides the pass holder and their spouse/domestic partner with free entry to many state parks during non-peak season (excludes Memorial Day till Labor Day – so get a library pass).
