I have seen that many out there want to know how and where to find the entrance’s to the new Cataclysm dungeons, so i thought i’d make a small guide to find all the new instance portals.
You find the entrance to Throne of Tides in Vashj’ir, Abyssal Depths and finally Abyssal Breach. Doing most of the quests in Vashj’ir will eventually lead you to a event/cut-scene quest at the Abyssal Breach. Tho you can just swim there to discover the entrance if you have no plans on questing there.
The Grim Batol entrance can be found in the western part of Twilight Highlands, by the entrance to the zone it self.
Halls of Origination lies beneath a huge pyramid in Uldum and are pretty close to the main questing hub.
So are The Lost City of the Tol’Vir, just a stone throw from Halls of Origination.
The Vortex Pinnacle lies up in the sky in Uldum and can be spotted from far away, just fly towards the towers in the sky and aim for the biggest tower. However, be sure to fly to the right towerclouds, the eastern ones. The western leads to the raid instance of Throne of the Four Winds.
The Stonecore is located in Deepholm, in the Temple of Earth, the main quest hub. Just go outside and fly up and west to find it, check the picture to see more specifically.
Blackrock Caverns are located in Blackrock mountain. It can be a bit tricky to find the right entrance, but if you follow the pictures you should find it.
Here is the entrance to Throne of Tides, Grim Batol, Halls of Origination, The Lost City of the Tol’Vir, The Vortex Pinnacle, The Stonecore and Blackrock Caverns.
Also, here’s a video showing the entrance of Blackrock Caverns, the screenshots could be somewhat hard to figure out!
