Driver in Naxos
 

We are hoping to travel to Greece in October and would like to hire a driver for one of the three days we are spending on Naxos. Any recommendations?

You shouldn’t have a problem finding a driver. Check the travel agencies, e.g. Naxos Tours and Naxos Sun when you get to the island, or just hire a taxi driver for the day. You needn’t pre-book for October, as the island won’t be busy by then.

I agree. It won't be a problem. You can easily wait until you're there to find a driver. Any travel office in Naxos town will be able to assist with this, and it's also likely that your hotel's owner/manager will have a cousin/uncle on tap for this.
