we have the two harms verlag 1/100000, which are not bad but not really good enough for walking so when Leen mentioned the F+B 1/50000 i got quite excited
the map has just arrived in our local shop, and as pointed out, it only covers certain areas, none being the plakias area. looks OK I will be getting a copy but not as a priority
HOWEVER!! there is another well detailed 1/50,000 map that covers all Crete,
the trick is being able to get your hands on a copy, the Greek military produces a very well detailed map and there are a few in private hands. (but not mine I may add)
