There are two places where you can find golden berries in the game. The first is in the Meadow zone. To get it, go to Spearow's obsticle hop and go to the near-top. If you look below, you will see a crate that you can break open. Drop down and break the crate to get the berry.
The second is in the Haunted zone, in the mansion. In the room where you entered, look to the right, you will see some vases that you can break open. Break them open and enjoy your golden berry.
