Crystal Cove State Park is a great beach. It offers beautiful ocean view hikes and tidepools. Day use is $15 per vehicle. $5 per hour parking is available year-round at the Los Trancos parking lot through the Yodel Parking app. It was our first date after the world shut down, and we spent a lot of time exploring the outside world.
It will be Fall time in Los Angeles, even if the weather does not always agree. A good family October activity is Irvine Park Railroad’s Pumpkin Patch in Orange County. It's a fun park with the extra enjoyment of a pumpkin patch. The Pumpkin Patch is located just behind the train station. Admission is free, but there is a gate entrance fee, and some activities are charged.
