Mirów and Bobolice by electric bike

Mirów and Bobolice are a pair of medieval strongholds on the Trail of the Eagles’ Nests, built in the mid-14th century under Casimir the Great on limestone outcrops. In the Niegowa municipality, they are joined by a rocky ridge under two kilometres long — one of the most photographed views in the whole Jura.

Bobolice Castle was thoroughly rebuilt between 2001 and 2011 and is open to visitors. The neighbouring Mirów Castle is still being rebuilt and remains a picturesque ruin; its inner courtyard can be visited at weekends.

Our Wataha loop (67.1 km) takes you to both castles: from the base in Olsztyn through Złoty Potok and Ostrężnik, Bobolice at km 38, Mirów at km 40, along the foot of the rocky ridge between them, and back through Żarki. It is our longest trail — a full-day ride, but with no technical sections; the electric assist greatly shortens the distance in feel.

You ride alone by GPS, at your own pace; a helmet and lock are included in the rental. The ridge between the castles is a walking trail — go up on foot.

If you prefer to start closer to the base, shorter loops run among the Eagles’ Nests around Olsztyn: Trop Wilka (24.7 km) and Dolina Szeptów (38.4 km).
