Tips from the Community
Section of the "Velo Mazovia" trail I don't know how one can recommend this. From the Zabraniec side, a "pump track", brutal transit traffic (noise), a large amount of sand and gravel deposited on the cycle path. Nothing pleasant, neither on a road bike nor on an MTB.

It is better not to venture into this area because it is a training ground and they issue tickets.

Be careful on the access paths to the roundabout - there are a lot of pedestrians and sharp turns.

A crossroads towards Warszawa Gocławek station and then on to MPK. ⚠️ Drive very slowly. The 90° turns are not suitable for bicycles. There are many pedestrians. I recommend caution.
