Budapest Metro Guide
Stepping into Budapest's metro system is like traveling through layers of history beneath one of Europe's most beautiful capitals. As the second-oldest underground railway system in the world, the Budapest Metro combines 19th-century charm with modern efficiency, making it an essential part of any visitor's experience. Whether you're heading to the thermal baths, exploring the Castle District, or discovering the vibrant Jewish Quarter, the metro will get you there quickly and affordably.
The network consists of four color-coded lines that intersect at key points throughout the city, operated by BKK (Budapest Transport Centre). Running daily from 4:30 AM to 11:00 PM, trains arrive every 2-15 minutes depending on the time of day. During peak hours, you'll rarely wait more than five minutes for your train.
Understanding the Four Metro Lines
Budapest's metro network comprises four distinct lines, each serving different parts of the city and connecting major attractions. The color-coding system makes navigation intuitive, with consistent signage throughout the stations.
M1 Yellow Line - The Historic Marvel
The M1 Yellow Line holds special significance as the oldest underground railway in continental Europe and a UNESCO World Heritage Site. Running beneath the elegant Andrássy Avenue, this line connects Vörösmarty tér in the city center with Mexikói út in the northeast.
The Yellow Line serves several must-visit attractions including the Hungarian State Opera House at Opera station, Heroes' Square and City Park at Hősök tere station, and the famous Széchenyi Thermal Baths at Széchenyi fürdő station. The stations themselves are architectural gems, featuring original 19th-century design elements that transport you back to the Austro-Hungarian era.
M2 Red Line - The Cross-City Connector
The M2 Red Line operates east-west, linking Déli pályaudvar (Southern Railway Station) in Buda with Örs vezér tere in Pest. This line was the first to connect both sides of the Danube, making it crucial for crossing between Buda and Pest.
Key stations include Kossuth Lajos tér for the Hungarian Parliament Building, Batthyány tér for access to the Fisherman's Bastion area, Astoria near the Great Synagogue, and Keleti pályaudvar (Eastern Railway Station). The Red Line intersects with other lines at Deák Ferenc tér and Keleti pályaudvar.
M3 Blue Line - The North-South Artery
The M3 Blue Line runs north-south on the Pest side, connecting Kőbánya-Kispest in the south with Újpest-központ in the north. This line serves many residential areas and provides important transport connections, including the crucial link to Budapest Ferenc Liszt International Airport via the 200E bus at Kőbánya-Kispest station.
Notable stops include Nyugati pályaudvar (Western Railway Station) and several interchange points at Deák Ferenc tér and Kálvin tér. The Blue Line has undergone extensive renovation to improve accessibility and modernize facilities.
M4 Green Line - The Modern Addition
The M4 Green Line, opened in 2014, represents the newest addition to Budapest's metro network. Running between Kelenföld vasútállomás in Buda and Keleti pályaudvar in Pest, this line passes under the Danube River and showcases award-winning modern architecture.
Important stations include Szent Gellért tér near the Gellért Thermal Baths, Fővám tér providing access to the Great Market Hall, and interchange stations at Kálvin tér and Keleti pályaudvar. The Green Line is fully wheelchair accessible, setting new standards for the entire network.

Tickets and Fares
Budapest's metro uses a unified ticketing system that works across all public transportation modes in the city. The variety of options ensures there's a suitable choice for every type of visitor, from quick single journeys to extended stays.
Single Journey Options
A single ticket (Vonaljegy) costs HUF 450 and allows one uninterrupted journey on any metro line, including transfers between metro lines within 80 minutes of validation. This flexibility makes it perfect for tourists who need to change lines to reach their destination. Block tickets offer slight savings for multiple journeys, with a pack of 10 tickets costing HUF 4,000.
Time-Based Passes
For visitors planning multiple trips, time-based tickets provide unlimited transfers between all transport modes. The 30-minute ticket (HUF 530) works well for short journeys, while the 90-minute option (HUF 750) accommodates longer trips with multiple changes.
Tourist-Friendly Passes
The 24-hour travelcard (HUF 2,500) and 72-hour travelcard (HUF 5,500) offer unlimited travel on almost all BKK services within Budapest, excluding only the 100E Airport Express. These passes eliminate the need to validate individual tickets and provide excellent value for active sightseers.
Monthly passes (HUF 8,950) suit longer stays, while students with valid EU student IDs can access discounted rates. The Budapest Card combines unlimited public transport with discounts on attractions, museums, and tours, making it an attractive option for culture enthusiasts.
Where to Purchase Tickets
Tickets are available from multiple convenient locations throughout the city. Purple ticket vending machines at metro stations accept both cash and card payments, with English language options available. The BudapestGO mobile app provides the most convenient purchasing method, allowing you to buy and validate tickets digitally.
BKK Customer Service Centres at major stations offer personal assistance, while newsstands and post offices provide additional purchasing points. Single tickets can be bought on some buses, though at a higher cost than pre-purchased options.
Using the Metro System
Successfully navigating Budapest's metro requires understanding the validation process and basic etiquette. The system operates on an honor basis with random inspections, making proper ticket validation essential.
Validation Process
Paper tickets must be validated before entering the metro area using the orange or yellow machines located at station entrances. Insert your ticket completely, wait for the validation sound, and retrieve it immediately. Mobile tickets purchased through the BudapestGO app require QR code scanning before boarding.
Travelcards and passes don't require validation but should be kept readily available for inspection. Traveling without a valid ticket results in fines of HUF 12,000 on the spot or HUF 25,000 if paid within 30 days.
Navigation Tips
Metro stations feature clear signage in both Hungarian and English, with color-coded directional indicators for each line. Electronic displays on platforms and inside trains show upcoming stations, while announcements are typically in Hungarian with key information understandable to international visitors.
Deák Ferenc tér serves as the central interchange hub where M1, M2, and M3 lines converge. Transfers here may involve walking through underground passages, but clear signage guides the way. The BudapestGO app provides real-time arrival information and can assist with route planning.
Operating Hours and Frequency
The metro operates daily from approximately 4:30 AM until 11:00 PM, with slight variations between lines. Train frequency varies throughout the day, with peak hours (8:00-9:00 AM and 5:30-7:00 PM) seeing trains every 2-5 minutes. Early morning and late evening services run every 10-15 minutes.
After metro service ends, an extensive night bus network maintains public transport coverage throughout the night. Tram lines 4 and 6 operate 24 hours along the Grand Boulevard, providing continuous service for nighttime travel.
Accessibility Features
BKK actively works to improve accessibility across the metro network, though the level of access varies between lines due to their different construction periods and historical significance.
The M1 Yellow Line, despite its UNESCO heritage status, unfortunately lacks wheelchair accessibility due to its historical construction. The M2 Red Line offers step-free access at select stations including Örs vezér tere, Pillangó utca, and Puskás Ferenc Stadion.
The M3 Blue Line has undergone complete reconstruction to become fully accessible, featuring new lifts and inclined elevators at all stations. The M4 Green Line sets the gold standard with complete step-free access via elevators at every station, though some locations require using two separate lifts.
All metro trains include designated wheelchair spaces marked with clear pictograms on accessible doors. The BudapestGO app displays real-time information about low-floor vehicle availability on various lines, helping passengers with mobility needs plan their journeys effectively.
Airport Connections
While the metro doesn't directly serve Budapest Ferenc Liszt International Airport, convenient public transport connections make reaching the city center straightforward and affordable.
The 100E Airport Express Bus provides direct service from the airport to key city center locations including Deák Ferenc tér, Astoria, and Kálvin tér. This premium service requires a special ticket costing more than regular public transport, and standard BKK passes aren't valid. The journey takes 30-60 minutes depending on traffic conditions.
Budget-conscious travelers can take Bus 200E from the airport to Kőbánya-Kispest, the terminus of Metro Line M3. Regular BKK tickets and passes are valid for this route, and the total journey time to downtown is approximately 45-60 minutes including the metro connection.
Practical Tips for Visitors
Maximizing your metro experience requires understanding local customs and practical considerations. Peak hours can be extremely crowded, particularly on weekdays between 8:00-9:00 AM and 5:30-7:00 PM. Traveling outside these times provides a more comfortable experience, especially when carrying luggage.
Personal safety and security require standard urban precautions. Keep belongings secure and remain aware of your surroundings, particularly in crowded areas. Some users report feeling less secure on the M3 line, so extra vigilance may be prudent.
Metro etiquette contributes to everyone's comfort. Stand right on escalators to allow others to pass on the left. Offer seats to elderly passengers, pregnant women, and people with disabilities. Allow passengers to exit before boarding, and remove backpacks in crowded trains to save space.
Ticket inspectors wear purple armbands and carry official identification. They conduct random checks throughout the system, so always keep your validated ticket or pass readily available. If you have doubts about an inspector's legitimacy, you can request to see their identification.
Digital Resources and Apps
The BudapestGO mobile app serves as an essential companion for metro travel, offering journey planning, real-time arrival information, and mobile ticket purchasing. The app supports NFC technology for one-step ticket validation and provides service alerts for planned disruptions.
The official BKK website (bkk.hu/en/) contains comprehensive information about routes, schedules, ticket prices, and service modifications. The English-language version makes it accessible for international visitors, while the FAQ section addresses common queries quickly.

Recent Updates and Future Plans
Budapest's metro system continues evolving to meet growing demand and improve service quality. Recent changes include potential plans for extended weekend operating hours and increased 24-hour bus routes to complement metro service.
The introduction of "metro bus" routes aims to improve connections between outer districts and existing metro lines, offering faster and more direct services. Ongoing renovations, particularly on the M3 line, may cause temporary service changes, so checking for current disruptions before traveling is recommended.
Changes to ticketing options and the MOL Bubi bike-sharing service integration demonstrate the dynamic nature of Budapest's public transport system. Always consult the official BKK website for the latest information about service changes and new features.
