IIRC, there are four elevators in total to get from the streel level to the PATH platforms.

Elevator 1 - There are street level elevators at the Church Street (East) and Greenwich Street (West) levels of the WTC Transit Hub/Oculus. You take this elevator down to the mezzanine level.

Elevator 2 - Directly adjacent to the Church Street elevator exit should be a second elevator to go down to the main floor level (where the Apple Store is). I think the Greenwich Street side elevator would be by the 1 Train Subway station near the Apple Store.

Elevator 3 - This one is a little hard to find. If you come in from Church Street, the elevator is on the LEFT side of the main floor; the Apple Store will be on your right. There's a wide flight of stairs leading down from the main floor to the PATH entrance turnstyles. If you bear to the far left, there is a walkway that dead ends at the elevator to take you down to the PATH entrance level.

Elevator 4 - This one will be after you go through the turnstyles (look for the ADA ones if you have luggage; they are easier to get through). There's elevators for the platforms normally used for the Hoboken Trains and another set for the platforms used by the Newark ones. If you use the LEFT Elevator 3, they will be pretty much in front of you when you hit the turnstyles.

Notes - I hardly use the Vesey Street entrance these days and I know there's no continuous escalator service down to the main floor level from that side. I know there is continuous escalators on the Church Street side next to the elevators. There's no escalator or ADA ramps from the main floor to the PATH entrance level - I normally drag my bags down the stairs instead of taking the elevator. There are escalators down to the platform level but sometimes they run one-way during rush hours (I haven't transited PATH since COVID).

Good Luck!
