Neva Bay
The northern coast of the gulf is high and winding, with abundant small bays and skerries, but only a few large bays (Vyborg) and peninsulas (Hanko and Porkkalanniemi). The coast is mostly sloping; there are abundant sandy dunes, with occasional pine trees. The southern shores are smooth and shallow, but along the entire coast runs a limestone escarpment, the Baltic Klint, with a height up to . In the east, the gulf ends with Neva Bay; in the west it merges with the Baltic Sea.
