Hi teetee,
as you turn off the prom from the new viewing area to go to the water taxis in Calis there is a shop on the right with steps up to it. The map is on one side a road map from Koycegiz (west of Dalaman) right down to Antalya, so yes it includes Kalkan and Kas. On the other side it is a road/street map of the whole of Calis and Fethiye. The map has a green and orange cover and they are usually displayed at the front of the shop. It was TL4.50 when we bought ours a year or so ago. The make is 'Bilge Maps'.
How's that for detail ?
Cheers,
John
