If you look at the page for the overall zone, http://ffxiv.gamerescape.com/w... there's a map there. Moving your mouse around the map will highlight the different zones :)
(It's on our list to do this for HW locations.. it's just a little lower on the priority list than other things atm...)
In the mean time, if you have any image editing skills you can feel free to create a map to share with others :) This is a Wiki, which means its editable by anyone.. if you create a map (or more than one), and it shows the right information, put it up here! If you can't figure out how to get it up here, upload the picture and I'll show you where it can go :)
