Named after Prof. Witold Sławiński, a famous biologist and Podlaskie country lover, this route should be most attractive for those interested in ethnography. It is marked green and runs through picturesque villages of the Czarna Białostocka and Wasilków municipalities in the western part of the Knyszyńska Primaeval Forest. The route starts at the bus stop in Czarna Białostocka. For a certain distance it covers the “Queen Bona” Route. The routes part as we reach a must-see Roman-Catholic church with an original antler decorated wooden interior. Both routes meet again by the Czapielówka Reservoir and run together to Czarna Wieś Kościelna – a folkcraft centre. The route enters the village at the blacksmith’s shop – one of the most active in Podlaskie. There are also some potters’ shops in the vicinity crafting grey pottery, the so called siwaki. You should also take note of the neo-gothic church constructed in 1912-1920. Further on, the route runs through Klimki to Wólka Ratowiecka. In Ratowiec the route passes by a watermill on the Czarna Rzeczka River and continues to another railway station in Czarny Blok. Leading through Wólka Przedmieście it reaches Katrynka where it crosses the No 8 national road – Białystok – Augustów. Next, through the “Góry Lence” Reserve, it reaches Jurowce and the nearby Open-air Museum of Podlaskie Countryside in Osowicze.
