There is a ton of free parking
Preferred parking is $14. This is the option we went with, thinking that we'd save ourselves when we were tired in the afternoon sun with a little shorter walk back. We were wrong. The only way this option would be worth the money is if you get to the park late in the day. We were there around 9:30 a.m. and the free parking spots that were closest to us were only a hundred yards (if that) from our $14 spot.
