Greece operates 15,862 kilometers of paved roads managed by the Hellenic Ministry of Infrastructure and Transport. The national highway network includes the A1 motorway connecting Athens to Thessaloniki over 550 kilometers, completed in sections between 1962 and 2017. The A2 motorway runs 670 kilometers from Igoumenitsa on the Ionian coast through Ioannina and across the Pindus Mountains to Thessaloniki. Tolls on Greek motorways range from 2.80 euros for short segments to 26 euros for the full Athens-Thessaloniki journey. Electronic toll collection through designated e-pass lanes operates on all major motorways. The Rio-Antirrio Bridge spanning 2,883 meters across the Gulf of Corinth opened in 2004 and charges 13.80 euros per passenger vehicle. Road signage displays Greek alphabet text with Latin transliterations on national highways, though secondary roads frequently show Greek only.
Driving requires a valid EU license or an International Driving Permit alongside a national license from non-EU countries. Greece drives on the right side. Rental agencies including Avis, Hertz, and Budget maintain offices in Athens International Airport and Thessaloniki Airport Macedonia, with daily rates starting around 25 euros for economy vehicles during off-peak periods. Insurance options include Collision Damage Waiver typically costing 15-20 euros daily and Third Party Liability mandated by Greek law. Many agencies impose restrictions on driving rental vehicles to certain islands, particularly Crete, requiring ferry transport or separate island rentals. Fuel costs averaged 1.85 euros per liter for unleaded 95 octane as of 2024. Parking in Athens costs 2-4 euros per hour in metered zones, with municipal lots charging 1.50-2.50 euros hourly. Blue zone parking in city centers requires prepaid cards from kiosks.
Greek Railways OSE operates passenger services primarily in northern Greece. The Athens-Thessaloniki route via Larissa runs six times daily with journey times of 4 hours 10 minutes on Intercity Express trains operated by Hellenic Train, the rebranded OSE subsidiary privatized in 2017.

Ferry services connect mainland ports to 227 inhabited islands. Piraeus port processes 20 million passengers annually across its 12 ferry terminals. Blue Star Ferries operates conventional ferries to the Cyclades with Athens-Santorini routes taking 5-8 hours depending on intermediate stops. Seajets and Golden Star Ferries run high-speed catamarans reducing Athens-Mykonos to 2 hours 30 minutes compared to 5 hours on conventional vessels.

Ferry schedules expand June through September with daily or multiple daily departures to major islands, while winter frequencies drop to 2-3 weekly sailings for many routes. Booking opens 2-3 months ahead for most operators. Passengers with vehicles should book at least three weeks ahead for July-August travel. Check-in closes 30-60 minutes before departure for foot passengers, 60-90 minutes when transporting vehicles. Delays from weather conditions affecting sailings occur most commonly December through February when meltemi winds in the Aegean reach 7-8 Beaufort scale. Crete receives service from three mainland ports: Piraeus to Heraklion takes 9 hours overnight on Minoan Lines or ANEK Lines for 35-65 euros deck class. Piraeus to Chania runs 8-9 hours. Patras to Corfu operates seasonally. The Ionian islands connect from Igoumenitsa and Patras, with Igoumenitsa to Corfu taking 90 minutes for 10-13 euros foot passenger fare.
Aegean Airlines and Olympic Air operate domestic flights from Athens International Airport Eleftherios Venizelos and Thessaloniki Airport Macedonia to 26 island and mainland destinations. Athens to Santorini flights take 45 minutes with fares ranging 50-150 euros depending on season and advance booking. Athens to Crete flights land at Heraklion or Chania in 50 minutes. Sky Express operates routes including Athens to Rhodes in 55 minutes, Athens to Mykonos in 40 minutes, and inter-island connections like Crete to Rhodes. Domestic flight prices increase substantially July-August, with advance booking 2-3 months ahead securing lower fares. Island airports including Mykonos, Santorini, Corfu, Zakynthos, and Kos operate seasonal international charters April-October while maintaining year-round domestic service. Thessaloniki to Corfu takes 55 minutes. Most island airports sit within 5-10 kilometers of main towns connected by bus or taxi.
Taxis in Greece display regulated meter rates starting at 1.29 euros with 0.74 euros per kilometer in urban areas and 1.29 euros per kilometer outside city limits. Night rates from midnight to 5 AM and rates during holiday periods increase by approximately 50 percent. Athens taxis charge a flat 38 euros from the airport to city center, while metered trips typically cost 35-50 euros depending on traffic and destination. Thessaloniki airport taxis to city center run 20-25 euros. Tipping rounds up to nearest euro or adds 5-10 percent for longer journeys. Ride-hailing services faced regulatory restrictions with traditional taxi lobbies, though Beat and FreeNow apps now operate legally in Athens and Thessaloniki connecting passengers to licensed taxis. Uber operates in limited capacity with professional drivers only.
Cycling infrastructure remains limited in Greek cities. Athens added 50 kilometers of bike lanes between 2020 and 2023, primarily in central districts, though lanes frequently disappear at intersections or share space with parked cars. Thessaloniki's waterfront Nea Paralia features a dedicated 3.5-kilometer cycling path. Bike rentals in Athens through operators like Funky Ride cost 15-20 euros daily. Several islands including Kos, Rhodes, and Corfu offer flat terrain suitable for cycling, with rental shops clustered near ports charging 8-15 euros daily for standard bikes, 20-30 euros for electric bikes. Mountain terrain on most Cyclades islands and in mainland regions makes cycling challenging without electric assistance. The EuroVelo 8 Mediterranean Route passes through western Greece covering approximately 850 kilometers from Igoumenitsa south through the Peloponnese.
Scooter and motorcycle rentals operate extensively on Greek islands. Daily rates range 20-35 euros for 50cc scooters not requiring motorcycle licenses, while 125cc motorcycles cost 30-45 euros daily requiring valid motorcycle endorsement. Helmet use became mandatory in 2012 with fines of 350 euros for violations, though enforcement varies by location. Insurance coverage typically excludes off-road riding and may require police reports for any incidents. Roads on islands including Santorini, Mykonos, and Paros feature steep grades, tight turns, and limited shoulders. Accident rates involving tourists on rented scooters prompted warnings from multiple foreign embassies.
Walking remains practical in compact city centers and island villages. Athens archaeological sites concentrate within a 2-kilometer radius of Syntagma Square connected by pedestrianized Dionysiou Areopagitou Street running 1.5 kilometers along the Acropolis southern slope. Plaka district northeast of the Acropolis restricts vehicle access on many streets. Thessaloniki's waterfront stretches 3.5 kilometers along Nikis Avenue suitable for walking. Island towns including Mykonos Town, Oia, and Rhodes Old Town feature narrow lanes built before automobile traffic. Marble or stone paving becomes slippery when wet. August midday temperatures in Athens average 33 degrees Celsius making morning or evening walking preferable.
Inter-island ferry hopping requires advance planning outside peak season. The Cyclades form a loose cluster allowing multi-island trips, though not all islands connect directly. Mykonos and Santorini maintain daily connections with several daily options in summer. Smaller islands like Folegandros or Sifnos may require routing through Piraeus or waiting for weekly sailings. The Dodecanese islands including Rhodes, Kos, and Patmos connect in a chain allowing northward or southward progression. The Ionian islands remain separate, with limited inter-island connections requiring returns to mainland ports. The Sporades operate separately from Cyclades and Dodecanese networks. Checking schedules across multiple operators through OpenSeas or Ferryhopper consolidator websites shows available routing options.
Vehicle ferries allow driving through the Peloponnese connecting to islands via shorter crossings. Kyllini port in northwestern Peloponnese reaches Zakynthos in 60 minutes and Kefalonia in 90 minutes. Gythio in southeastern Peloponnese connects to Kythira in 2 hours 45 minutes. Neapoli reaches Kythira in 60 minutes. These shorter crossings cost less than Piraeus routes, with vehicle transport running 25-40 euros. The Peloponnese itself contains Nafplio, Mystras, Ancient Olympia, and Monemvasia within driving distances under 3 hours between sites.
Road conditions vary significantly by region and road classification. National highways including the A1 and A2 maintain two or three lanes each direction with shoulders and regular service areas. Secondary roads connecting villages often narrow to single lane with pullouts, lacking center lines or shoulders. Mountain roads through the Pindus range and across Crete feature hairpin turns and steep grades without guardrails. Snowfall closes mountain passes including the Athens-Delphi road and routes through Epirus December through March. Road maintenance standards decline on secondary routes with potholes developing after winter. Livestock including goats and sheep wander onto roads in rural areas particularly dawn and dusk.
Athens traffic congestion peaks 8-10 AM and 5-8 PM weekdays with stop-and-go conditions on major arteries including Kifisias Avenue, Syngrou Avenue, and Vouliagmenis Avenue. The Attiki Odos ring road provides bypass options for 7.80 euros full circuit toll. Thessaloniki experiences similar rush hour patterns concentrated on Tsimiski Street and Egnatia Street through city center. Parking enforcement in both cities operates 8 AM-9 PM with wheel clamps applied to violators, requiring 80 euros release fee plus outstanding fines. Island traffic concentrates July-August when rental vehicle numbers surge, creating bottlenecks in towns like Fira in Santorini and Mykonos Town where streets accommodate only single-file traffic.
Gas stations in rural areas and on smaller islands may close Sundays or operate limited hours. Credit cards face acceptance issues at unmanned automated pumps requiring euro bills. Carrying 20-30 euros cash for fuel purchases proves useful. Diesel fuel marked as "πετρέλαιο" costs less than unleaded gasoline marked "αμόλυβδη". LPG stations appear less frequently than in other European countries.
Archaeological sites impose entry fees ranging 6 euros for smaller sites to 20 euros for the Acropolis. The multi-site ticket in Athens covers the Acropolis, Ancient Agora, Roman Agora, Hadrian's Library, Kerameikos, Temple of Olympian Zeus, and Aristotle's Lyceum for 30 euros valid five days. EU students under 25 enter free with student ID. All visitors enter free on specific days including March 6, April 18, May 18, last weekend of September, October 28, and every first Sunday November through March. Delphi charges 12 euros, Olympia 12 euros, Epidaurus 12 euros. Combined tickets at multi-component sites save 2-4 euros versus separate entries.
Tram service in Athens operates three routes totaling 27 kilometers connecting Syntagma Square to coastal areas including Glyfada and Voula. Route T3 runs from Syntagma to Faliro Peace and Friendship Stadium. Routes T4 and T5 split at SEF continuing to Glyfada and Voula respectively. Trams operate 5 AM to midnight weekdays, extended to 2 AM weekends. The 1.20-euro integrated ticket valid 90 minutes covers tram, metro, and bus transfers.
Funicular railways operate at two locations in Greece. The Lycabettus Funicular in Athens climbs 210 meters to the summit of Lycabettus Hill in 3 minutes, departing every 30 minutes for 7.50 euros return. The Katara Pass road crosses the Pindus Mountains at 1,690 meters elevation connecting Ioannina to Metsovo, remaining Greece's highest paved mountain pass open year-round weather permitting.
Water taxis operate in harbors including Spetses, Hydra, and between Aegina and Agistri. Hydra island prohibits private vehicles maintaining transportation by donkey, water taxi, or foot. Water taxis from Hydra port to Kamini beach 2 kilometers distant cost approximately 12 euros per boat seating up to six passengers. Spetses water taxis run similar rates for harbor pickups and beach transfers.
Island hopping by private yacht charter operates through companies including Sunsail, Dream Yacht Charter, and local operators departing from Athens, Corfu, and Rhodes. Bareboat charters for 40-foot sailing yachts cost 2,500-5,000 euros weekly depending on season, requiring sailing certifications. Crewed charters with skipper and optional cook run 8,000-15,000 euros weekly for similar-sized vessels. Marina berths in peak season require advance booking with costs of 50-100 euros nightly depending on yacht length and marina location.
Bus schedules in smaller towns reduce significantly during afternoon hours 2-5 PM and cease entirely by 8-10 PM. Sunday and holiday service operates at reduced frequency, sometimes dropping to 2-3 departures daily on intercity routes. Confirming return schedules upon arrival prevents stranding, particularly in winter months when some routes operate only weekdays.
Highway tolls accept cash in euros at staffed booths and automated machines that may reject worn or foreign bank notes. The e-pass system requires pre-registration online with credit card and license plate details, offering no discount but providing convenience. Missed toll payments result in fines mailed to vehicle registered addresses, complicated for rental vehicles potentially triggering agency administrative fees.
Regional airports on islands including Kalymnos, Astypalea, and Ikaria operate limited schedules, sometimes only 2-3 weekly flights to Athens on small aircraft. Sky Express serves these routes with 50-seat turboprops. Booking well ahead becomes essential as flights fill quickly, and alternatives require lengthy ferry connections.
