Audio Guide of Tunnel of Eupalinos

The tunnel is usually open from Wednesday to Monday, from 08:30 to 15:30, and closed on Tuesdays. I always recommend checking before you go on the official website of the Greek Ministry of Culture, as opening hours may change depending on the season.

Standard admission costs €8, and there is a reduced rate of €4 for students and EU citizens over 65. An excellent way to save money is to buy the combined ticket that includes the Pythagorion Archaeological Museum.

The guided visit inside usually lasts about 20 to 40 minutes depending on which section you choose to walk through. In total, allow at least one hour to get there, put on the safety equipment, and enjoy the experience without rushing.

It is a marvel of 6th-century BC engineering and a UNESCO World Heritage Site, famous for being the first tunnel in history excavated simultaneously from two ends and meeting with millimetric precision. You can read more about its history at UNESCO World Heritage.

The ideal time is early in the morning (08:30 - 09:00) to avoid the heat on the walk up to the entrance and to miss the large tour groups. In summer, the inside of the tunnel offers cool relief, but the wait outside can be hot.

Unfortunately not; the tunnel is narrow, damp, and requires visitors to crouch in several sections, so it is not suitable for wheelchairs or for people with claustrophobia. If you have mobility difficulties, we suggest enjoying the exterior views and the nearby museum instead.

Take advantage of being in the area to visit the picturesque village of Pythagoreio and the Monastery of Panagia Spiliani, which offers incredible views. The impressive Heraion of Samos is also very close by.

Wear closed, non-slip shoes, as the floor may be wet, and be ready to use the mandatory helmet provided there. If you are tall, you will have to walk bent over for part of the route, so take it slowly.
