The Keravanjoki (Swedish: Kervo å; the Kerava River) is a river in Finland. The 65-kilometer-long river starts from Lake Ridasjärvi in Hyvinkää.[1] The Keravanjoki is a tributary of the Vantaa River that flows into the Gulf of Finland at Helsinki.[2] As the name implies, the river runs through the town of Kerava.
