The only reason I rate this four is because our driver Demetrius worked very hard to become the tour guide. He did an excellent job but said to us when we got Rethymno, he wood pick us up at the same place, we ask if he was our tour guide and found out he was just the driver. After much debate he became the tour guide. We did see everything on the tour and you need good shoes because some of the walking is hard. The lake was not worth the trip but if we had a regular tour guide it might have been better.
