It only arrives. When you enter, park and then walk to the gift shop. There you pay to enter the garden. They charge $5 for adults and $3 for children under 12 years old. They give you some stickers to show that you have already paid and a piece of paper that has information about the garden. Then you walk towards the entrance and enter the garden.
