The Latvian State Institute of Wood Chemistry can be reached from the city centre by taxi (8 km) or public transport. We suggest using the bus 21 from city centre.
If you are taking the bus 22 from the Riga Airport, get off the bus at the stop "Autoosta" and switch to bus 21 to reach the Latvian State Institute of Wood Chemistry (stop "Zemitāna laukums" and a 5 min walk).
