During our stay on Naxos, we had planned to do some island hopping.  Unbeknownst to us, because we were there so late in the season (1^st week of October), most of the inter-island day trips had finished.  Not being one to easily let a dream die, I decided to ask around at most of the many day tour places in the town.  I found that my best options were on offer from the  Naxos Tours office at Chora Naxos Protodikion square, Naxos 843 00, Greece.  The friendly staff helped me book a Greek Island tour for my day trip to Koufonisi.
