About Naxos

The Portara, a leftover gateway to an unfinished temple of Apollo, stands on its own islet beside the Hora. Inland, mountain villages sell graviera and kitron liqueur, and the coast runs from Agios Prokopios to the long sweep at Plaka. June through September covers the beach season, with the meltemi wind building through July and August and keeping the heat more bearable.

Portara (Temple of Apollo gateway) draws sunset crowds - arrive 45 minutes early for space on the causeway. Mornings are better for empty photos.

Kastro museums and the Venetian tower charge small fees. Beaches are free; umbrella sets cost extra on organised stretches.
04Meltemi & Scooter Caution
Summer meltemi winds can be strong - secure hats and avoid novice scooter rides in gusts. Water shoes help on pebble beaches south of town.
