We drove past that on our way to a village in the hills. The coast around Rethymno looked nice driving along route 90; we did not visit the town itself. We're not beach people and preferred the hills inland. There are photo opportunities all over the place; seriously, it's just trigger-happy shooting on the island when it comes to let's say pretty holiday snapshots, which is what I mostly made there. can't go wrong; have fun.
But....how? We spent an afternoon exploring the city center. Waste of time, really.
