My initial research has confirmed that Crete is one very big island with so much to offer. A little about us - we are a Mom, Mom's friend and Mom's daughter. All very fit so staying active and having lots to do is high on our list. We will be in Crete for 4 full days in mid Oct. (arriving by boat from Santorini) so that doesn't give us a lot of time to explore. Since the gorge is a "must do" should we stay the whole time in Chania? If so, is it better staying near or in the old town? We don't want to be too far from shops and restaurants but certainly don't mind walking a few kilometers if we find a really great place. Or would we be better off splitting the trip with two days in Rethymno and two in Chania. Any and all suggestions welcome.
