Greece operates 116,631 kilometers of paved roads as of 2021 according to the Hellenic Statistical Authority. The national highway system includes the A1 (Ethniki Odos) running 550 kilometers from Athens to Evzoni on the North Macedonia border, the A2 (Egnatia Odos) spanning 670 kilometers from Igoumenitsa on the Ionian coast to Kipoi at the Turkish border, and the A7 connecting Athens to Corinth and continuing south through the Peloponnese Peninsula for 205 kilometers to Kalamata. The A8 links Patras to Athens via the Rio-Antirrio Bridge, which opened in August 2004 with a main span of 560 meters and total length of 2,880 meters. Electronic tolling (e-PASS system) operates on most motorways with cash payment still accepted at staffed booths. Tolls on the A1 from Athens to Thessaloniki total approximately 22 euros for passenger vehicles as of 2024.
Greece requires an International Driving Permit for non-EU visitors alongside a valid home country license. The minimum driving age is 18 for passenger vehicles and 21 for motorcycles over 125cc. Traffic moves on the right side of the road. Speed limits are 50 kilometers per hour in urban areas, 90 kilometers per hour on rural roads, 110 kilometers per hour on major highways, and 130 kilometers per hour on motorways unless otherwise posted. The blood alcohol limit is 0.05 percent for drivers with more than two years experience and 0.02 percent for those with less. Police conduct random breath tests and vehicle document checks particularly during summer months and holiday periods.
Rental car companies operate in Athens International Airport Eleftherios Venizelos (designated ATH by IATA), Thessaloniki Airport Macedonia (SKG), Heraklion Airport Nikos Kazantzakis (HER), and in city centers throughout mainland Greece and islands served by car ferries. Companies require drivers to be minimum 21 years old with some agencies setting age 23 or 25 for specific vehicle categories. A credit card in the primary driver's name is mandatory for deposit holds ranging from 300 to 1,500 euros depending on vehicle class. Collision Damage Waiver and Theft Protection are typically offered as optional additions to base rental rates. Daily rates for economy vehicles average 25 to 45 euros in low season (November through March excluding Christmas) and 50 to 80 euros in high season (July and August) based on 2024 pricing from major international chains.
The road from Athens to Cape Sounion covers 69 kilometers along the Attic Peninsula coast via Poseidonos Avenue becoming the 91 coastal road. The Temple of Poseidon sits 60 meters above sea level on a rocky promontory at the cape's southern tip. Construction occurred between 444 and 440 BCE using marble from nearby Agrileza quarries. Fifteen of the original 34 Doric columns remain standing. The route passes through Vouliagmeni, where a thermal lake maintains constant temperature between 22 and 29 degrees Celsius year-round due to underground hot springs mixing with seawater through subterranean channels. Driving time from central Athens to Sounion is 75 to 90 minutes outside rush hour periods.
The Peloponnese Peninsula loop connecting Corinth, Mycenae, Nafplio, Epidaurus, Sparta, Mystras, and Olympia covers approximately 650 kilometers. The Corinth Canal cuts 6,346 meters through the Isthmus of Corinth with width of 24.6 meters at sea level and walls rising 52 meters. Construction began in 1881 and completed in 1893 after initial attempts by Roman Emperor Nero in 67 CE were abandoned. The archaeological site of Mycenae sits 278 meters above sea level in the northeastern Peloponnese. The Lion Gate entrance, built around 1250 BCE, features a relieving triangle with two lionesses carved in limestone flanking a central column. The Treasury of Atreus tholos tomb has an interior chamber diameter of 14.5 meters and corbelled dome height of 13.2 meters, constructed using precisely cut conglomerate blocks without mortar around 1250 BCE.
Nafplio served as the first capital of modern Greece from 1829 to 1834 before the capital moved to Athens. The old town occupies a peninsula beneath Palamidi fortress, which contains 999 steps from sea level to the main gate according to local count, though actual number varies slightly depending on route taken. Epidaurus lies 30 kilometers east of Nafplio. The Ancient Theatre of Epidaurus, designed by architect Polykleitos the Younger in the 4th century BCE, seats 14,000 spectators across 55 tiers. The orchestra circle measures 20 meters in diameter. Acoustics allow a coin dropped in the center to be heard in the top row 60 meters away, though this claim requires minimal ambient noise and favorable atmospheric conditions.
The drive from Nafplio to Sparta covers 109 kilometers via Tripoli. Modern Sparta occupies a different location from ancient Sparta, which left minimal architectural remains due to Spartan cultural emphasis on military over monumental building. The Byzantine ruins of Mystras sit on Mount Taygetos slopes 6 kilometers west of modern Sparta. The fortified city was founded in 1249 by Frankish crusaders and became capital of the Byzantine Despotate of Morea from 1349 to 1460. The Palace of the Despots occupied the upper town section, while monasteries including Peribleptos and Pantanassa were built in lower and middle sections. Mystras was abandoned in 1832 after Greek independence, preserving structures from the 13th through 15th centuries.
Olympia lies 175 kilometers west of Sparta via mountain roads through Megalopoli. The archaeological site contains the Temple of Zeus, built between 470 and 456 BCE in Doric style with dimensions of 64.2 by 27.7 meters. The temple housed a 12-meter-tall chryselephantine statue of Zeus created by sculptor Phidias around 435 BCE, counted among the Seven Wonders of the Ancient World until destroyed in the 5th century CE. The ancient Olympic stadium, located 200 meters east of the sanctuary, measured 212.54 meters in length with earthen embankments accommodating approximately 45,000 spectators. The first recorded Olympic Games occurred in 776 BCE and continued every four years until Roman Emperor Theodosius I banned them in 393 CE as part of campaigns against pagan festivals. The Archaeological Museum of Olympia displays the Hermes of Praxiteles marble sculpture discovered in the Temple of Hera in 1877, attributed to sculptor Praxiteles from approximately 330 BCE, though some scholars argue it is a Roman copy.
The route from Athens to Delphi covers 180 kilometers northwest via the A1 motorway to Thebes, then national road through Livadeia and Arachova. Delphi sits on the southwestern slopes of Mount Parnassus at elevation between 380 and 700 meters above sea level. The Sanctuary of Apollo contains the Temple of Apollo, reconstructed in 330 BCE after earthquakes destroyed earlier versions built in 650 BCE and 510 BCE. The temple measured 60.3 by 23.8 meters with 6 by 15 Doric columns. The Oracle of Delphi functioned from the 8th century BCE until closure by Roman Emperor Theodosius I in 393 CE. Pythia, the priestess who delivered prophecies, sat on a tripod above a chasm in the temple's adyton inner chamber. Geological surveys conducted in 2001 identified two fault lines intersecting beneath the temple that likely released ethylene gas, which produces euphoric effects at low concentrations. The ancient theatre at Delphi was built in the 4th century BCE with capacity for 5,000 spectators on 35 rows. The stadium, located at the site's highest point, measured 177.35 meters in length with seating for 6,500 on stone tiers added during the 2nd century CE by Herodes Atticus.
The mountain village of Arachova sits 12 kilometers east of Delphi at 960 meters elevation. The settlement dates to at least the 14th century CE. Parnassus Ski Center operates on Mount Parnassus slopes at elevations between 1,600 and 2,260 meters with 23 runs totaling 36 kilometers. The ski season typically runs from December to April depending on snowfall. The resort opened in 1976 and underwent significant expansion in 1993. Driving from Delphi to Arachova takes approximately 15 minutes via the national road.
The route from Delphi to Meteora covers 230 kilometers north through Lamia and Trikala. Meteora's sandstone rock formations rise up to 400 meters above the Thessalian plain. Geological processes formed the rocks from a river delta cone deposited approximately 60 million years ago when the area was submerged beneath the Tethys Sea. Erosion from wind, water, and seismic activity shaped the current pillars. Christian hermits occupied caves in the rocks from the 11th century CE. The first monastery, Megalo Meteoron (Great Meteoron), was founded in the 1340s by monk Athanasios Koinovitis. At peak, 24 monasteries operated on the rock formations. Six remain active as of 2024: Great Meteoron, Varlaam, Rousanou, Holy Trinity, St. Nicholas Anapausas, and St. Stephen. Access to monasteries required rope ladders and nets until the 1920s when staircases were carved into the rock faces. Great Meteoron sits at 613 meters elevation and houses a museum displaying monastic artifacts and manuscripts.
The drive from Meteora to Ioannina covers 145 kilometers west through the Pindus Mountains. The route crosses Katara Pass at 1,705 meters elevation, one of the highest paved passes in Greece. Ioannina sits on the western shore of Lake Pamvotis at 470 meters elevation. The lake covers 22.8 square kilometers with maximum depth of 11 meters. The city served as capital of the Despotate of Epirus from 1358 to 1479 and was controlled by Ottoman ruler Ali Pasha from 1788 to 1822. Ali Pasha's fortress occupies a peninsula extending into the lake. An island in the lake contains five monasteries dating from the 16th and 17th centuries. The museum in Monastery of St. Panteleimon displays the room where Ali Pasha was assassinated on January 24, 1822 by Ottoman forces. Bullet holes remain preserved in the wooden floor.
Vikos Gorge lies 35 kilometers north of Ioannina within Vikos-Aoös National Park. The gorge runs 20 kilometers from Vikos village to Konitsa with depth reaching 900 meters between the cliffs of Mount Tymfi. The Guinness Book of Records listed Vikos as the deepest canyon in the world proportional to its width in 1989, with depth-to-width ratio of 1:2.5 at its narrowest point. The Voidomatis River flows through the gorge with water temperature remaining between 4 and 10 degrees Celsius year-round. Hiking the gorge length requires 6 to 8 hours starting from either Monodendri or Vikos village. The trail follows the riverbed with several sections requiring rock scrambling. Mountain villages of Zagori occupy the slopes above the gorge. These 46 villages known collectively as Zagorochoria feature traditional architecture using local slate and stone construction. Arched stone bridges span mountain streams, with Kokoris Bridge (1750 CE), Plakidas Bridge (1814 CE), and Kalogeriko Bridge (1814 CE) among the best preserved examples.
The Egnatia Odos (A2 motorway) connects Ioannina to Thessaloniki covering 265 kilometers. The modern highway follows the approximate route of the ancient Via Egnatia, constructed by Roman proconsul Gnaeus Egnatius in 146 BCE to connect Dyrrhachium (modern Durrës, Albania) with Byzantium (modern Istanbul, Turkey). The ancient road crossed through Apollonia, Thessaloniki, Amphipolis, and Philippi. Archaeological remains of the Roman road surface are visible in sections near Kavala and Thessaloniki. The modern A2 opened in segments between 1994 and 2009 with total cost exceeding 5.5 billion euros. The highway crosses several major bridges including the Aoos River Bridge with main span of 280 meters and the Sfaltos Bridge with arch span of 150 meters.
Thessaloniki occupies the Thermaic Gulf coast in northern Greece. The city was founded in 315 BCE by Cassander of Macedon and named after his wife Thessalonike, half-sister of Alexander the Great. The White Tower on the waterfront was built by the Ottomans in the 15th century CE on the site of earlier Byzantine fortifications. The tower stands 34 meters tall with diameter of 23 meters and wall thickness of 4.8 meters. The Rotunda was built by Roman Emperor Galerius around 306 CE as either a mausoleum or temple. The circular structure measures 24.5 meters in diameter with walls 6.3 meters thick and dome rising to 30 meters. The interior contains 4th-century CE Christian mosaics added when the building was converted to a church. The Arch of Galerius was erected in 298 CE to commemorate victory over the Sassanid Empire. The arch originally consisted of four main pillars supporting a dome over the intersection of two perpendicular arcades. Only three pillars and one arcade survive, covered with marble relief panels depicting battle scenes.
The Archaeological Museum of Thessaloniki displays artifacts from excavations throughout Macedonia region. The museum's Vergina Gold collection includes the larnax containing remains identified as Philip II of Macedon, father of Alexander the Great. The gold chest weighs 11 kilograms and measures 41 by 33 by 18 centimeters, decorated with the Vergina Sun symbol. Philip II was assassinated in 336 BCE at Aegae, the ancient Macedonian capital located at modern Vergina 75 kilometers southwest of Thessaloniki. The royal tomb was excavated in 1977 by archaeologist Manolis Andronikos. The tomb's main chamber measures 4.46 by 5 meters with 5.6-meter-high barrel vault. Frescoes on the facade depict a hunting scene with figures identified as Philip II and Alexander the Great based on iconographic analysis.
The drive from Thessaloniki to Mount Olympus National Park covers 90 kilometers south via the A1 motorway. Mount Olympus rises to 2,918 meters at Mytikas peak, the highest point in Greece. The mountain has 52 peaks above 2,000 meters. Olympus National Park was established in 1938 covering 238 square kilometers. The park was designated a UNESCO Biosphere Reserve in 1981. Eight hiking trails ascend from different starting points to summit areas. The most common route begins at Prionia (1,100 meters elevation) and climbs 7.5 kilometers to Spilios Agapitos Refuge (2,100 meters), then continues 3 kilometers to Mytikas summit. The ascent from Prionia to summit requires 6 to 8 hours. Summit attempts are typically made from May to October when routes are snow-free, though weather conditions can change rapidly even in summer months with temperature dropping below freezing and visibility reducing to near zero. The first recorded ascent of Mytikas occurred on August 2, 1913 by Swiss photographer Frederic Boissonnas and Greek guide Daniel Baud-Bovy.
The coastal route from Thessaloniki to Kavala covers 165 kilometers east following the Aegean Sea coastline. Kavala occupies an amphitheater-shaped bay dominated by a Byzantine fortress on a peninsula. The fortress dates to the early 15th century CE when Byzantine Emperor Manuel II Palaiologos fortified the site. The Kamares aqueduct crossing the old town was built during the reign of Ottoman Sultan Suleiman the Magnificent in 1530 CE, likely on foundations of a Roman aqueduct. The structure measures 280 meters in length with maximum height of 25 meters and consists of two levels of arches, with 60 arches total. The Imaret, a large complex built in 1817 CE by Muhammad Ali of Egypt who was born in Kavala, functioned as an Islamic school and charitable institution. The building now operates as a hotel but retains original architecture including domed prayer halls and courtyard fountains.
