Anyone know how to get to these 2 arenas?

I've seen maps on the internet from various places indicating there's two more arenas that many players I've run into can't seem to find. Could they be part of a quest or perhaps taken out at launch and just existed in beta? I know the areas where the arenas should be exist, it's cleared out on my overhead map and in both cases I get to a gate with no arena guard or way to get in.

1. First one is in the northeast part of Henge of Denravi. Head up on a ledge to the north and as you climb it you come across a vine gate....but no arena guard. This one has a name to it....Fort Kog.

2. Second one is in northern Ammonn. Head straight behind a few of the merchant/trader tents and up over a sandhill, then you come across a wooden gate....but same thing....no arena guard.

Any help and/or suggestions is greatly appreciated!

Several of the arenas were combined into the Competition Arena in Lion's Arch. The only arenas are:

Ascalon City
Yak's Bend
Lion's Arch
Draknor's Forge
Tomb of the Primevil Kings

ty Theclam....I kinda figured it was that and the pics I've seen on the net were probably taken in beta.....
