The journey begins in Chalki, the historic heart of Naxos, and gently unfolds westward through the olive groves of the Tragaia Valley. From the very first steps, the landscape invites the walker into a rural setting, where stone paths, ancient trees, and open horizons create a sense of calm and continuity.
The trail continues towards the imposing rock of Apano Kastro. A challenging side path reveals medieval fortifications, ruined Byzantine and post-Byzantine churches — including the roofless Panagia Kastriani — and panoramic views over central and southern Naxos.
Descending from the castle, the route heads towards Ano Potamia, passing the church of Agios Andreas, renowned for its well-preserved 14th-century frescoes. The walk concludes along a wide stone-paved medieval road connecting the Potamia valley with the Tragaia plateau.
The route unfolds through the fertile Potamia valley, where traditional villages preserve their authentic architecture amid watermills, chapels, stone towers, and cultivated land. Along the way, hikers pass through an ancient landscape shaped not only by nature but also by early human presence, including the Naxos Necropolis, a Geometric-period burial site (9th–8th century BC) hidden among the rocks, where circular tomb remains offer a rare glimpse into the island’s earliest communities.
