You can pick up your pass at the Season Pass Office or the Ticket Windows. You can find a map of the resort here: https://www.7springs.com/the-mountain/about-the-mountain/trail-maps.aspx
If you purchased your pass in advance online, you have the option to use Mobile Pass through the My Epic app rather than a season pass hard card. This allows you to go straight to the lift using your phone as your pass. Please visit https://www.epicpass.com/app.aspx for more information about how to activate and use your Mobile Pass.
