Once you leave the coastline, the roads of Naxos are pretty much empty, even in August. But you may have to contend with some very strong winds, some sharp gradients and perhaps a herd of goats, being shepherded by a lame sheep dog. Still, some of the long descents in the south west of the island are a joy to ride, even on a €7 a day hire bike (a heavy hybrid). You'll also pass the odd historic landmark, as well as picturesque white-washed chapels.
