This isn't a complete guide, but rather an explanation of what I did to get this achievement after getting the other three location achievements and completing all the side missions.

I started by checking through each area and it appeared that all maps were fully revealed. I messaged several recent winners to ask if they had remembered going anywhere unusual or out of the way and PSYCHO POOCH suggested that I check an area in Tycho's Ribs called "Compression Chamber" that popped the achievement for him. As soon as I entered this area, the achievement popped for me:

Hope this helps.

UPDATE: Per Rob25X in th ecomments:
I suggest mentioning the only 'missable' area in the game appears to be 'Hyperion Contigency Armory' in the Eye of Helios mission (mid way through the game - chapter 9). I believe every other area in the game is covered by natural progression or exploration post game. You could also mention that if co-op players continue in the game and you yourself are idle you may not 'explore' areas.
