After Parikiá, the northerly fishing port of Náoussa is the island’s second town but primary resort area. The oldest quarter actually forms a kástro a Venetian town-planning device seen also at the heart of Antíparos where the backs of the houses form a defensive perimeter, and access could be denied to pirates by means by closing a limited number of entrances. The old fishing port is achingly picturesque and knows it, given the prices charged at most nearby restaurants.
The closest escape is the Environmental and Cultural Park of Aï Giánnis Détis, a car-free area beginning at the eponymous monastery on the peninsula closing off Náoussa bay on the northwest. Seven well-mapped and marked hiking trails crisscross the peninsula with its stunning rock formations; the most popular pair of paths, numbered ‚1‘ and ‚2‘, take you to the handsome 1887-vintage, British-built lighthouse at Cape Kórakas. Using the most direct path from the events amphitheatre above the car-park and snack-bar, allow a minimum 40 minutes round-trip to the lighthouse; in September the landscape is covered in the waving, snow-white fronds of sea squill (Drimia maritima).
