The geographical relationship between Ghiscar (Old Ghiscar, Astapor, Meereen) and what's left of Valyria is clearly shown on the map, "The Lands of the Summer Sea", in A Storm of Swords

(But she was travelling north, as least when passing (through) Ghiscar, as she was following the coast, whether aboard ship or on land.)
