There are basically two different routes to reach Bialowieza from Warsaw: one through SIEDLCE and other one through BIALYSTOK. They both meet in HAJNOWKA, a small town at the border of National Preserve Forest, about 15 km west from Bialowieza. (See the map below.)
The route through Bialystok is a
combination of train Warsaw - Bialystok
and bus Bialystok - Bialowieza, with a possible change
of bus at Hajnowka.
The route through Siedlce is a combination of train Warsaw - Siedlce - Hajnowka (change of a train at Siedlce) and a bus Hajnowka - Bialowieza
It is also possible to hire a taxi from Hajnowka to Bialowieza, with an estimated cost of 80 zl (20 US $) or less.
