Alonatzia is a small picnic spot just north of the village of Kato Mylos in the Pitsilia hills, at about 870 m. It sits on the shore of the village's little irrigation reservoir — a pocket of water that stays full year-round and feeds the fruit orchards around it — with pine trees shading the ground along the bank. It is a local-scale place rather than a big forest station, and that is exactly its charm.
The site doubles as a trailhead. The easy Alonatsia nature trail starts right at the picnic area and runs about a kilometre towards Agros, mostly under pine shade, passing the chapels of Agia Paraskevi and Archangelos Michael, which also serve as viewpoints over the valley. The longer Agros – Kato Mylos route passes directly by the site too, Diosmides - Geratzia begins under a kilometre away, and Agios Ioannis Pitsilias is about 1.5 km off — so the same spot can anchor anything from a half-hour stroll to a proper Pitsilia walking day.
