Treasure Chests

I can't seem to get access to one of the chests the Bahdok Caverns one, when I take the route provided on Guild wars wiki, there's a gate in the way and there is no other way around to get to it. I've beat NF but this gate is closed, how do I get passed the gate?

If you're going into the Explorable Area, there shouldn't be a gate down anywhere.

you don't go in through the mission you go in through the explorable.. there's a guy there that you talk to past the guy that starts the mission and past the storage agent. he'll let you into the explorable where the gate is open.

Here is a link to the map on the wiki http://gw.gamewikis.org/wiki/Image:B...p_location.JPG

You can also come in from the north entrance. I have done this three times and do not remember a gate that you can't go around.

Ahh thank you very much, I was entering through the mission
