"Do not touch" in Bahdok Caverns?

I've tried getting to the "do not touch" in the Bahdok Caverns, but I can't seem to get to it. I've found two locked gates at the top and bottom of the area.

Is there a way to unlock the doors so I can explore the right-hand side of the caverns?

Thanks!

I haven't been there yet but that generally indicates that you need to follow the story to get there, completing either primary quests or a mission.

Thanks DeanBB.

I've done the mission in the caverns, so I guess there is a quest somewhere I have yet to complete.

talk to the guy in front of the gate. He should then allow access

Make sure you are in the explorable area of Bahdok Caverns, not in the mission (Moddok Crevice).
