This time of year weekends are 9 to 5. Parking opens 30 minutes early and if you are smart, arrive 30 minutes before that. Parking waits can be as long as 30 minutes or more.
9am-5pm regular hours. You'd be better off checking the website for the hours since they do change throughout the season. The hours are on their main page.
