Arriving in Riga:


Riga International Airport (RIX) is located 13 kilometers southwest of the city center. There are direct flights from many directions to RIX. You can see the list of airlines here.

There is a tourism information bureau Welcome to Riga in Sector E (Schengen area). We recommend you to visit it and take a free map of Riga. You can also purchase Riga public transport tickets, phone cards, etc. using your credit card.

From Airport (Lidosta) to the city center (Old Riga - Vecrīga)

Bus No. 22 / Minibus No.222: It costs €2 (if you buy a ticket from the driver; €1,15 if you buy a ticket ahead of time). There is a "ticket vending machine" in the bus stop. You can check the time table here / here and the route here / here.
"11.novembra krastmala" and "Autoosta" are the closest stops to the old town.

Taxi: A queue of taxis will be waiting for you outside the arrivals area. A typical ride to Old town Riga or the city center should cost no more than €15.


The website is here. The bus station is very close to the old town. After leaving the bus station, you can see the old town on your left.
Two international bus companies are Ecolines and LUXExpress.


The train station is also very close to the old town. There are many different exits and so it is better to ask the direction to the old town.
There are train connections from Moscow, St. Petersburg, and Minsk. You can check the website here and time table here.


There are plenty of accommodation options available in walking distance from the conference venue as it is located in the heart of the city. Many options can be found here.

Getting around:

Riga is more than 800 years old. Each century has left its marks in the architecture in the Old Town and City Center, where the cultural heritage coexists with the quick pace of modern living.

From the University of Latvia, you can reach many tourist attractions by foot. A walk in the Old Town is one of the things you can't miss. See the map below with some easily reachable attractions from the conference venue.

Travel tips and more information can be found in, Wikitravel and Live Riga.
