A 36–45 km island loop links the Temple of Aphaia, Agios Nektarios Monastery, the Perdika fishing village and Marathonas Beach in roughly 60–75 minutes of driving. Aegina's public bus network is limited, so this loop matters for efficiency as well as comfort: island timetable changes can leave gaps of several hours, while a rental car keeps the schedule under your control. The Temple of Aphaia is the easiest place on the island to verify your insurance and parking plan at the same time, with a small on-site parking area, roadside overflow parking, and a clear access road that suits compact cars. Economy car rentals start from around €25/day, making a self-drive loop the most practical way to combine the archaeological sites, southwest-coast tavernas and the island's beaches in a single visit.
