Why is the park closed today? I spent over a month planning this trip with my family just to find out the park is closed today. What reason is there to close the park in the middle of the week?

They're closed on Tuesday and Wednesday. You should have checked the park hours before planning the trip sorry

The last month before the park closes for "winter" and the first month of opening, the park closes tuesday and wednesday. And may close on regular open days for weather related problems.

Park is closed Tuesday & Wednesday. Says it right on Google. Sorry for your luck. Next time definitely check if park is opened or closed the day you want and that it's not a blackout date if you have a pass.
