She took the wrong path to get to Villa Jovis. That is the wrong gate. Villa Jovis' gate is a grilled gate.
Sounds like she's in Villa Lysis?
Tell her to look at the map when she walks and she can check where she is going.
I'm stretching my brain to remember but I think that when she 'jumps to' - there are 2 paths one on the left and one to the right with a tree close to the start of the path.
She should take the right path and this path then splits in to upper and lower.
The lower path goes to Villa Jovis.
