At the Amphitheater just north the Huntington Beach Pier.
Free parking is only available a few blocks away where there are no meters.
You can usually find good spots up 6th Street. There's going to be racers, advanced fitness skaters and beginners so don't be intimidated. The purpose for the skate is to meet new friends and have a nice relaxing skate. We stop there and regroup again. On the way back we skate straight through back to the HB pier with no stops.
