If you have your own car or have rented, then you can easily come from Athens in about 2 hours and 15 minutes.
Following the Attiki Odos and then the Athens - Corinth National Road, immediately after the Isthmus, go right at exit 10 (Corinth - Epidavros) and immediately after, turn left, under the bridge, on the road that leads to the Baths of Beautiful Helen and continues to Epidaurus.
Drive for about 40 minutes and reach the junction for Epidaurus. Just before you will see signs to Poros or Spetses. At the intersection, turn right and immediately turn left, under the bridge.
Continue on this road, meeting on your right the supermarket "Vassilopoulos" . A little further down you meet another intersection, in which there is a sign that points "towards Poros". At this point you will turn left and continue on your way to Poros.
After about 25 minutes you will reach the settlement of Agioi Apostoloi, where you will find a crossroads with signs, right for Poros and left for Methana. At this intersection you will follow the route to the right for Poros and you will reach Galatas in about 10 minutes.
The road is an extension of the National Road, quite good and for the overall route, at an average speed, you need about 2 hours and 15 minutes.
From Galata you pass by your car opposite Poros with the small ferry boats. Small ferry departures are every 30 minutes, full and half hours.
