From the PM:
“If tested negative, then the stay-in-zone Order applies, whereby tourists are required to [remain] on the property for the duration of their stay. The tourist will be allowed to visit attractions within the resilient corridor,” the Prime Minister explained.

So, it seems that you must remain on the property, unless you are visiting attractions within the Corridor.
And of course following all the safety protocols.
