  • An Adventure Pass is required for parking in the main lot during the day, and can be purchased at the Cosmic Cafe.
  • Mount Wilson's elevation is 5,700 ft.  Those with heart or respiratory problems may have trouble with the altitude.  It is also much cooler on the mountain in the evenings - come prepared with warm clothing.
