A good map is not easy to find but this one is a very accurate one. Well it was in 2002 - the only map I found on the entire internet of Calis:

As you can see, Fethiye is about 2 minutes walk from the Mutlu, and Koca Calis is a few steps past the Seketur. Things were far easier to get to back then. It also uses the compass favoured by English people living in the South of England.
