Guild Wars 2

I have 100% world completion, but I am trying to get all the exploration achievements, however I can’t figure out what areas I am missing or find a way to tell. I am missing 2 areas from the Krytan achievement, 3 from the Maguuna, and 1 from the Shiverpeak.

Is there any way to tell which zone I am missing these from? or do I have to literally walk over the entire area of every zone until I find it?

Go on the wiki and find a map of one of the Kryta zones. Check one by one the named areas then open your ingame map to see if you are missing any of them.
The locations in the explorable achievements are always named locations, so just looking at a map and comparing with yours is enough.

For the Maguuma Explorer look for Aurora’s Remains, south west of Brisban’s Wildlands, it’s an area commonly missed.

Might come in handy.

Not really. That map has only vistas/skillpoints/hearts/pois what the OP needs are area names: http://wiki.guildwars2.com/images/2/2b/Queensdale_map.jpg

This map of Queensdale for example has all the names in it, like Village of Shaemoor, Western Divinity Dam etc, THOSE count for the explorable achievements.

Oww, my bad, got my links messed up.

I used this one to help me find those last regions: http://wiki.guildwars2.com/wiki/User:Bluestone/Explorer

Do take note that the zones added with Events (such as Halloween) are not listed. For example Vexa’s Lab and Forsaken Halls.

One thing you can start with is check if you’ve been to all the mini dungeon areas.
