Hehe.
There is the "north", called Tol Barad Peninsula, and the "south", the actual PvP zone like Wintergrasp.
The "north" is always accessible by both factions. Here you can complete 6 random dailies.
The "south" is accessible when you control Tol Barad. An additional 6 dailies can be completed here as well when your faction controls it. These, too, are mostly random and change after every Tol Barad battle.
So, in total, you can complete 12 Tol Barad dailies a day.
As to answer the OP: If your faction controls it, you should see your factions symbol on the "south" area (Tol Barad) of the map.
