Wikimedia Hackathon 2025/Travel

Istanbul, Turkey – May 2–4, 2025

Visa

Istanbul is a global transport hub, mainly an air hub. Istanbul has two international airports (Istanbul Airport and Istanbul Sabiha Gokcen Airport), which connect Türkiye with more than 180 locations on the world. Located at the intersection of Asia, Europe and the Middle East, Istanbul Airport is a strategic connection point for all destinations and the second busiest airport in the world.

Istanbul is also connected to European capitals with a railway. There are also bus links with neighboring and European capitals.

Türkiye has a very flexible visa policy and provides citizens of foreign countries with various options for obtaining a visa. At the moment, citizens of 95 countries can travel to Türkiye without a visa, and in addition to this, citizens of 22 countries can obtain an electronic visa to travel to Türkiye.

Visitors of most nationalities must hold a passport valid for no less than 150 days from the date of arrival. An identity card is accepted instead of a passport for citizens of Azerbaijan, Belgium, Bulgaria, France, Georgia, Germany, Greece, Hungary, Italy, Liechtenstein, Luxembourg, Malta, Moldova, Netherlands, Northern Cyprus, Poland, Portugal, Romania, Spain, Switzerland, and Ukraine.

Check if your passport is up to date and if you will need a visa (or an e-visa) to travel to Turkey; citizens of most countries can apply for an e-visa online.

As of 2024, Türkiye has embassies and consulates in 252 locations around the world. Turkish diplomatic missions are represented on all continents. Türkiye is the third country with the highest number of diplomatic representations in the world. You can see the full list of Turkish diplomatic missions on this link.

Money

Turkish lira (TRY, TL, or ₺) is used in Istanbul and throughout Türkiye. You can use your credit, debit, or prepaid card in the city (restaurants, cafes, bars, shops, pharmacies, etc.). However, please note that you should only use Turkish lira (₺) as cash and that you will have to change money at a currency exchange office or use an ATM. There are currency exchange offices and ATMs (Visa, MasterCard, American Express) at Istanbul Airport (IST) and Sabiha Gökçen International Airport (SAW). This will allow you not to waste time withdrawing money or converting currencies. You can pay in Turkish lira in cash in all taxis and with your card in most of them.

We recommend paying everywhere in Istanbul with a bank card (Visa, MasterCard). If you prefer digital payment methods such as Apple Pay and Google Wallet, you can also use these methods in most places.

The exchange rate for Turkish lira changes frequently, so be sure to check online for the daily rate. For instance, while doing an internet search on February 6th, the exchange rate for 1 euro to Turkish lira is 37.25 TRY.

Also, if your mobile supports e-sim, you can activate apps like Airalo or Mobimatter.

Public transport

There are several types of public transport available in Istanbul, which are:

Metro

Istanbul is among the cities with the most metro lines in the world. Weekday function starts at 06:00 and ends at 00:00. However, on weekends (between 06:00 on Friday morning and 00:00 on Sunday), there are 36-hour uninterrupted metro services. The places where you see the and symbols are metro stations. The Istanbul Metro is the fastest and most efficient way to get around the city.

Bus

One of the most effective ways to get from one place to another in Istanbul is by bus. You can access the timetables of the buses, which can be easily distinguished by their yellow color, from this link: https://iett.istanbul/en

Metrobus

Metrobuses, operated by IETT, the public institution that operates the buses, are highly preferred because they are fast, traffic-free, and have their own private highway.

The places where you see the symbol are Metrobus stations.

Taxis

Applications such as BiTaksi and Uber can be used to find taxis in Istanbul.

Please be aware that, like many other touristy cities, Istanbul taxis are driven by profit and may try to scam tourists. Regrettably, Istanbul taxi drivers are not reputed for their honesty, so we suggest minimizing the use of taxis. If needed, consider using taxi apps or relying on public transportation.

Commitment from Wikimedia Foundation on LGBT+ related issues at the Wikimedia Hackathon

The Wikimedia Foundation in its role supporting the community organizers of the annual Wikimedia Hackathon global conference affirms its December 2020 commitment of support for LGBT+ volunteers. Specifically, the staff supporting each year's Hackathon Organizing Team will make available to them educational and planning resources to encourage efforts to support both in-person and virtual LGBT+ attendees. Additionally, when advisable according to the guidance of the Foundation’s human rights team, the Foundation will facilitate discussions between the Hackathon Organizing Team and local government officials to address the safety of participants, and between the Hackathon Organizing Team and the Wikimedia LGBT+ affiliate to address any other needs identified for LGBT+ participants.

We recognize that no host city can perfectly address all concerns, and will work with the Hackathon Organizing Team and Wikimedia LGBT+ to identify and communicate potential risks which cannot be offset. Finally, the Foundation will also continue "being vigilant that incidents where individuals are targeted for identity factors are properly recognized and addressed in our Trust & Safety systems."

The Wikimedia Foundation invites community organizers and entities to join our commitment and document their commitments and ideas for supporting LGBT+ participants of the Wikimedia Hackathon and other community organized events.
