Orange County, CA is a wonderful place to explore. There is great shopping at Fashion Island in Newport Beach as well as South Coast Plaza in Costa Mesa. If you are a more active person, there is always fun surfing down in Huntington Beach. Also a very fun activity to do on the weekends is to play beach volleyball. There are nets set up right next to the Huntington Beach Pier. It's a great way to get that awesome California tan while getting a work out in.
Weekdays are fun in Huntington Beach too, there is a farmers market on Main Street in Huntington Beach, CA every Tuesday night. They always have great booths out there with good entertainment and you will see our RE/MAX Fine Homes agents there. The local restaurants also have Taco Tuesday for a fun & festive dinner.
Hope this gives you some ideas on what goes on in the beach cities!
