Walking in Saint Petersburg from Narvskaya to Obvodny channel and back around

Walking in Saint Petersburg from Narvskaya metro station to Ivan Chernykh and Rozenshtein streets to the Obvodny Canal emb. past the Red Triangle factory (in the old days many thousands of worked here). Let’s enjoy the silence and turn to Staro-Petergofsky prospect and then Narvsky prospect. Return back to the Narvskaya metro station.
