You can't really get any further here, so back we go and along the road.

You can walk around behind the Fürstenau upper lock, but you should wear sturdy shoes. It can be a bit slippery on the slope. Caution: Pigeons live in the lock; don't be alarmed, they only flutter around when disturbed.

No entry, as on any railway bridge ;-)

To get from the left side of the canal to the right, you have to carry bicycles or other devices up a steep embankment.

An old disused railway bridge, located much higher than the single track along the Masurian Canal.

Quite impressive, after such a long time. The 5 zloty entrance fee is fine.
