The Finnish–Russian border is the roughly north/south international border between Finland and Russia. Some 1,340 km (833 miles) long, it runs mostly through uninhabited taiga forests and sparsely populated rural areas, not following any particular natural feature or river. It is also part of the external border of both the Schengen Area and the European Union.
Border crossings are controlled and patrolled by the Finnish Border Guard and Border Guard Service of Russia, who also enforce border zones (0.1–3 km on the Finnish side, at least 7.5 km on the Russian side). Entry to a border zone requires a permit. The electronic surveillance on the Finnish side is concentrated most heavily on the "southernmost 200 kilometers" and is constantly growing in sophistication. The Finnish Border Guard conducts "regularly irregular" K9 patrols to catch anyone venturing into the border zone. Russia maintains its 500-year-old border patrol in the arctic region as elsewhere and plans to upgrade Soviet border technologies to both save on cost and to fully maximize the efficiency of the Border Service by the year 2020. But Lieutenant-General Vladimir Streltsov, deputy head of the Russian border service, noted that electronic surveillance will never replace the human element.
The border can be crossed only at official checkpoints, and at least one visa is required for most people. Major border checkpoints are found in Vaalimaa and Nuijamaa , where customs services on both sides inspect and levy fees on imported goods.
The northern endpoint of the border between Norway, Finland, and Russia form a tripoint marked by Treriksrøysa, a stone cairn near Muotkavaara (69°03′06″N 28°55′45″E / 69.05167°N 28.92917°E). On the south, the boundary is on the shore of Gulf of Finland, in which there is a maritime boundary between the respective territorial waters, terminating in a narrow strip of international waters between Finnish and Estonian territorial waters.
