This tour will take you from Warsaw to Treblinka, one of the most notorioius WWII camps. Once you leave Warsaw there is a decent recently constructed expressway in the direction of Bialystok. Once you leave it, you'll be driving through forrests and then countryside. This part is really nice. Entering Treblinka and the part to the memorial, the roads are in a bad condition. One could easily imagine they date back to WWII. The memorial is just a memorial park with a very small museum on the left as the Germans destroyed all evidence still during the war. Finally, on the way back you will go via Wyszkow and Pultusk to Zegrze lake, a very popular WE spot for people from Warsaw. The final stretch will bring you back to Warsaw partially over the route already covered. Have fun!
