Shipwreck Park in Dana Point used to have spooky sails and a mast greeting the children at a fairly regular playground. Now the decorative mast is missing, but the play structure is designed as a pirate ship.
There are a few more to add to the list of Pirate Parks in Orange County. These are posts I still need to update with new photos since playgrounds have been updated from when I originally posted:
18. I especially like the Dotson Park (Stanton) pirate ship because its black! And I love the details of the X marking the spot and the treasure chest. (Note for Summer 2023: Splash pad closed at this park for maintenance. It was also the site of a tragic shooting on a busy Saturday afternoon in April 2023. A local father was killed right outside the park. I always trust the advice of families who live in the neighborhood. I’m hearing them warn to avoid this park for now.)
