There are lots of good map sites out there for Dark Age of Camelot.  All you need to do is Google "daoc maps" and you should find some very good links.  However, Gothwaite maps are a little harder to find.

Back when we were playing DAOC, we couldn't find any Gothwaite maps (nor can we to this day, actually), so we created these:

Gothwaite Harbor map  (PDF)
Caer Gothwaite map     (PDF)

- These maps are a little rough around the edges, but they still serve their purpose. They were "hand drawn" (literally in the case of Caer Gothwaite)

Hope you find them helpful!
