Sunny Fields Park at Solvang, Solvang, California.

This is quite an exciting park. I'd say it is almost more fun than Solvang itself. My 3.5 year old had a blast. Just be careful around the slides on the back side of the park. Others mentioned they are very high off the ground. They are about 2.5 feet or better off the ground. We saw a few kids get hurt while we were there. Not a huge deal, just make sure they don't go headfirst or have no clue before they play. Good times, highly recommend this park.
