Do we need a resevation for friday the 3rd of September for the group Moon buzz

Not really

Yes, if you plan on parking in the lot. If you are walking up from anywhere else (such as a friend's house or from Grant's Trail) then there is a contact tracing form to fill out by scanning a barcode from your phone and no online reservation is needed.

Yes you need to do it online

Parking reservation, yes

Yes most definitely

Yep. That is how you get your entry pass for the parking lot

Yes you need a reservation for everything now.. I had to make one just to visit on a regular day.

I would call and make one yes.
