Sumqayit is in Azerbaijan.
Sumagit is a one of the biggest industry oriented city of its time during the USSR period. There were nearly 90 heavy to medium industrial plants but nowadays only 5 or 6 of them remain. The city was planned and built in 1950s as to be 3-4 km (1.8-2.5 mi) away the industrial zone to minimize the pollution effects on people that is why the coast line of the city consists of so much green area.
One can reach Sumgait by bus or taxi from Baku. Since gas prices are as low as water prices in Azerbaijan, only an estimated cost 5 Shirvan (10AZN) should be expected for a destination of Baku to Sumgait by taxi. You can bargain though, and the taxi drives can go as low as to 3.5 Shirvan.
It is around 45 km (28 mi) (30-40 min) from Baku center Targovi to Sumgait coast (Göyercin).
