Useful Information

Public Transportation

Budapest’s public transportation systems are operated by the Centre for Budapest Transport (BKK). The service includes buses, trolleybuses, trams, underground trains (Metro), and above-ground suburban trains (HÉV). Buses, trams, and trolleybuses run daily from 4:30 a.m. until 11:00 p.m.

Three of the four recent metro lines interconnect at the Deák tér station, two interconnects at the Keleti pályaudvar (Eastern Railway) station. Service frequencies range from 15 minutes late in the evening to every two minutes at peak times. Tickets or passes must be bought before boarding. They are available at BKK Customer Service Points, ticket offices at metro stations, and from the driver on board, but the best option is to use vending machines throughout the city.

Please note that the front-door-boarding-only policy is in place on some of the bus lines (including 100E from the airport to the city). Additionally, you can try the MOL Bubi public bike-sharing scheme as a new mode of public transport in Budapest, which consists of 76 docking stations and 1,100 bicycles.

Budapest’s excellent night bus system has just been upgraded to 40 lines.

Please note that to make sure that everyone has a ticket, the transport company has hired uniformed ticket inspectors who check for tickets on board.

You can expect very pleasant temperatures during the day in May. The average maximum daytime temperature in Budapest in May lies at 23.0°C (73.4°F). The average minimum temperature is 12.7°C (54.86°F) (usually the minimum temperature is noted at night). The amount of rain during this month is moderate with an average of 61mm (2.4in). It rains an average of 9 days of a month. If you enjoy blue skies and sunshine, then this is a great time to go to Budapest with 234 hours of sun. May is known as one of the best months to visit Budapest.

Pack clothes that are light and suitable for late spring/early summer. Take hats and sunglasses to shield your eyes from the scorching sun. It’s important to make sure that you drink plenty of water to keep yourself hydrated, as well as to use UV protection. A light trench coat or rain poncho is a must-pack, as is an umbrella.


The registration fees do not include provisions for the insurance of participants against personal accidents, illness, cancellation, theft, property loss, or damage. Participants are advised to take adequate personal travel insurance.


The Hungarian currency is the forint (Ft or HUF). If you want to exchange your currency to forint, always do so at an official exchange office. Never exchange money in the streets with random strangers, since this is prohibited by law, and also represents a huge risk anyway. The exchange rates applied in Budapest banks, official exchange offices, and hotels may vary. Average exchange rate: 1 Euro = 395 HUF in February 2023. Money withdrawal from ATMs is mostly in forint, but in the city center, there are multiple non-bank ATMs, where euro withdrawal is available, too.

Cash payments that do not end in 5 or 0 will be rounded to the closest 5 or 0, e.g. for HUF 152 you pay HUF 150, and for HUF 158 you pay HUF 160. All prices in shops are gross prices including VAT.

Credit Cards

In general, VISA, EC/MC, and American Express credit cards are accepted in most restaurants, cafes, shops, and petrol stations, please check the emblem at the entrance.

Stores and Shopping

The opening hours of Budapest stores are generally 10:00-18:00 on weekdays and 10:00-13:00 on Saturdays. The big shopping centers are open from 10:00-20:00 from Monday to Saturday and from 10.00-18.00 on Sunday.


Budapest’s pharmacies (“gyógyszertár” in Hungarian) are well stocked and can provide medicaments for most common ailments. Each of the 23 districts has an all-night pharmacy open every day, a sign on the door of any pharmacy will help you locate the closest one.


The voltage in Hungary is AC 230 V / 50 Hz. Electrical plugs are „Type F” (for European standard 2-pin sockets).


If you drive a personal or rented car, always try to park at a guarded parking lot and do not leave any valuables in the car. Please note that Budapest is divided into paying parking areas, with one parking meter in each street. The maximum parking time duration and tariffs may vary between different parking zones.
