Getting there & away
Treblinka is about 100km northeast of Warsaw, a two-hour drive away. Take Rte 8 towards Białystok, and 15km north of Wyszków turn right on road No 694 (signposted Ciechanowiec). When you reach Małkinia (26km from the main road), take the first turn on the right (again signposted Ciechanowiec), then go right again immediately after the railway (road No 677 to Przewóz). You cross a rickety wooden bridge over the Bug River, then cross a railway line to reach Treblinka village (4km from Małkinia). Continue for another 4km through the hamlet of Poniatowo; the entrance to the site is the first turn on the right after you cross the railway line again.
Małkinia lies on the Warsaw–Białystok railway line; there are hourly trains from Warszawa Centralna every two hours, and more frequent ones from Warszawa Wileńska station (14zł to 22zł, 1¾ hours). There are no buses to Treblinka so your only option (other than an 8km walk) is to take a taxi from the train station; reckon on paying between 60zł and 120zł, depending on how long you want the taxi to wait.
