Most visitors to Aegina stay close to the port and the beaches, which means the island's interior is largely theirs alone. A network of old paths threads through the pistachio and olive groves, climbs the flanks of Mount Oros in the south, and links the scattered hamlets that are too small to appear on most tourist maps. Walking these routes in the early morning, before the sun is high, you have the landscape almost entirely to yourself — the only sounds the cicadas, the wind in the pines, and occasionally a dog announcing your passage through someone's property.

The ascent of Mount Oros, the island's highest point at just under five hundred metres, is the most ambitious walk on Aegina and still a very manageable half-day for anyone reasonably fit. The route begins near the village of Pachia Rachi and climbs steadily through scrub and rock to the Byzantine chapel of Ellanios Zeus at the summit. The views from the top take in the whole island, the Saronic Gulf, and on a clear day the distant shapes of the Peloponnese and the mountains of Attica. The walk up takes roughly ninety minutes at a comfortable pace; the descent is faster. Bring water and start early in summer.

For a gentler walk, the path from Aegina town through the pistachio groves towards the village of Mesagros follows flat or gently sloping ground through some of the island's most productive agricultural land. In September, when the pistachio harvest is underway, you may see families working along the route. The path is not always clearly marked but is straightforward enough to follow, and the round trip takes about two hours.

The walk from Perdika along the coastal path heading north is short but rewarding, offering views across to Moni island and back towards the town. It is most enjoyable in the late afternoon when the light is soft and the temperature has dropped. The path deteriorates after about forty minutes but the initial stretch is easy and suitable for all ages.
