I was told the entry was free but it cost to park. Does anyone know the cost for parking?

Minimum time is 2 hours, so the basic fee is $4. If you are willing to walk, there's an overflow lot near the Children's garden without a fee. Season passes are worthwhile if you come more than 4 times in a season.

There is a little free parking up the road from the main entrance.

We parked in the overflow lot and the walk wasn't bad at all!

2 an hour
