Vatican City operates as an enclave entirely surrounded by Rome. No airport exists within its 0.49 square kilometers. Visitors arrive through Rome's Leonardo da Vinci–Fiumicino Airport, located 32 kilometers southwest of the Vatican, or Ciampino Airport, 15 kilometers southeast. From Fiumicino, the Leonardo Express train reaches Roma Termini station in 32 minutes, with departures every 15 minutes. From Termini, Metro Line A stops at Ottaviano-San Pietro, 500 meters from St. Peter's Square. Buses 64 and 40 also connect Termini to the Vatican area. From Ciampino, buses run to Termini or Anagnina Metro station. Taxis from Fiumicino to the Vatican cost 48 euros fixed rate during daytime, 55 euros from 22:00 to 06:00. Visitors entering Vatican City cross directly from Rome on foot—no passport control exists at the border. The main public entrance is through St. Peter's Square, accessible 24 hours daily, though the basilica and museums maintain separate hours.
Vatican City adopted the euro as its official currency in 1999, despite not being a European Union member. The arrangement exists through a monetary agreement with Italy, permitting the Vatican to mint limited euro coins with papal imagery. Vatican euro coins are legal tender throughout the eurozone but are minted in small quantities—typically 70,000 to 100,000 sets annually—making them collector items that rarely circulate. Visitors should carry euros in cash. Vatican Museums accept major credit cards (Visa, Mastercard, American Express) for ticket purchases and museum shops. ATMs do not exist within Vatican City proper, though multiple machines line Via della Conciliazione and surrounding Roman streets within 200 meters of St. Peter's Square. Currency exchange offices operate along Via di Porta Angelica and Via della Conciliazione. Exchange rates match standard Roman rates, typically 3 to 5 percent below interbank rates. Banks in Rome offer better rates than exchange offices, but require more time. Vatican City issues its own postage stamps, sold only at the Vatican Post office near St. Peter's Square and within the Vatican Museums. These stamps must be used on mail posted from Vatican postboxes, as Italian stamps are invalid within Vatican territory and vice versa.
Vatican Museums require advance ticket purchase, strongly recommended due to daily visitor limits. General admission costs 17 euros for adults. The ticket price drops to 8 euros for students aged 6 to 18 and for university students up to age 25 with valid identification. Children under 6 enter free. Online reservations add a 4-euro booking fee per ticket but guarantee entry at a specific time. Tickets purchased online must be collected at the museum entrance or displayed on mobile devices. The museums close most Sundays except the last Sunday of each month, when admission is free but requires advance online reservation due to overcrowding—visitor numbers on free Sundays regularly exceed 30,000. St. Peter's Basilica charges no admission fee. Entry to the basilica dome costs 10 euros for the 551-step climb via stairs only, or 8 euros to ascend 231 steps after an elevator carries visitors to the first level. The Vatican Necropolis and St. Peter's Tomb require separate advance booking through the Excavations Office, costing 13 euros per person. These tours are limited to 12 people per group and must be booked weeks or months ahead during peak season. Vatican Gardens tours cost 36 euros and must also be reserved in advance.
Dress codes are strictly enforced at all Vatican sites. Knees and shoulders must be covered for entry to St. Peter's Basilica, the Sistine Chapel, and all Vatican Museums. Guards stationed at entrances turn away visitors in shorts, miniskirts, sleeveless tops, or low-cut clothing. Hats must be removed indoors. No exceptions are made for religious or cultural grounds beyond the stated modesty requirements. Long scarves or wraps can satisfy the requirement if carried in a bag and worn before entry. Security screening mirrors airport procedures. Visitors pass through metal detectors and submit bags for X-ray examination. Backpacks and large bags exceeding 40 x 35 x 15 centimeters are prohibited and must be checked at the free cloakroom. Tripods, selfie sticks, aerosols, glass containers, weapons of any kind, and pointed objects including knitting needles are forbidden. Food and drinks except small water bottles are not permitted inside museums or the basilica. Photography is allowed in most areas except the Sistine Chapel, where guards actively enforce a no-photography rule introduced to protect the frescoes and maintain contemplative atmosphere. Speaking loudly or talking on mobile phones inside the Sistine Chapel results in verbal warnings or removal.
