Joensuu locates about 450 kilometers to North-East from Helsinki and it is a capital city of North Karelia area with over 74 000 inhabitants.
From Helsinki you can reach Joensuu normally three different ways:
1. by airplane
Joensuu airport international code is JOE. Planes are landing to Joensuu several times every day , Sundays and July are the most quiet seasons. Mostly planes are Finnair
or Norra planes. Ask your travel agency, you can fly to Joensuu example by Air France tickets etc. www.finnair.com
. Helsinki airport locates in city of Vantaa, so name of airport is Helsinki-Vantaa. Believe or not: sometimes plane between Helsinki-Joensuu can be cheaper than train.... Airport of Joensuu is about 10 km from Joensuu center, busses and taxi cars are very quick going to city center and to main bus station next to Sokos hotel Kimmel. There are good discounts in summer time with Helsinki-Joensuu flights.
2. by train
Finnish trains are very comfortable and not very expensive if you buy your ticket in time. Our national railway company, VR, website is www.vr.fi
(also in English). There is a train connection to Joensuu trains from Helsinki airport (change train at Tikkurila stop). Cheaper "saver" train tickets are sold earliest 60 days before trip and I think latest about two weeks before your trip, if discount tickets are still available. Cheaper "saver" tickets are about 25 €/one way. (Basic tickets are about from 41 euros to 56 euros /one way.) Sometimes you can get flight to Joensuu, with about same rate, specially in summer :-) . You can take local train from Helsinki-Vantaa airport to Tikkurila or Helsinki railway station and jump to Joensuu train. Or you can take a Finnair bus from airport to Helsinki main railway station.
3. by bus
Also usual way (and cheap) to travel between Helsinki-Joensuu. Busses are ok to travel and tickets and timetables you can find from portal www.matkahuolto.fi
(also in English). You can travel also in the night, there is one night bus leaving from Helsinki-Vantaa airport to Joensuu about 2 AM (not in Saturday or Sunday), travel time about 8 hours. From internet you can buy these bus tickets in lower price earliest 32 days before trip. Bought from a bus, ticket is little more expencive. Credit cards are not always accepted in matkahuolto busses, so prepare with cash.
Also low fare bus company, Onnibus, operates between Helsinki-Joensuu-Helsinki. This Onnibus company website you find from http://www.onnibus.com/en/index.htm. Cheap rate in one way can be example 15 euros (or cheaper) between Helsinki-Joensuu, depends how early bird rate you get. Onnibus does not accept cash, so you have to pay it by debit/credit card even in a bus. From airport you have to take train or bus to Helsinki center bus station (Kamppi, near Helsinki railway station) to get in the Onnibus going to Joensuu. Changes possible.
