Virolahti sector is located about 7 km after Virolahti (road #7 or old road to Hamina), on the right side of the road there is a blue sign 'museum'. Immediately after it is an exit to the dirt road, and then you need to follow the signs. The museum has a detailed plan of the fortifications. There are about 6 bunkers on the museum territory, but there are much more abandoned bunkers along the forest road that goes northeast to Miehikkala direction. A good landmark is the line of obstacles. There are also numerous bunkers south of the highway.
Miehikkälä sector has the main large museum of the Salpa Line on 4 hectares. There are bunkers, field fortifications, cannons. You need to drive from Virolahti at the crossroads to the right (to the north). In Miehikkala itself, the road turns sharply left from the church - you don't need to go there, otherwise you will get into a grader (although the graders there are good). From the church to the museum is about 2 km.
Luumäki sector is located on the Kuovala - Lappeenranta highway (No6). The fortifications are located across the highway about 10 km. from Taavetti. As landmark can be used Motel Luumäen. The first bunkers are about 1 km behind it (see the sign Salpa asema). The line is extended to the northwest-southeast from Lake Kivijärve to the bogs is about 1.5–2 km.
Finland is not Russia, as you know. And the scales are not the same, and the roads are not the same absolutely, and there are always signs on the roads - what, where and how much to go. It is written, of course, in Finnish. But what does it mean for an experienced traveler to learn a dozen words in a native language? 'Bunkkeri', 'museum', 'Salpa-asema' as well as 'päivää', 'hyvä', 'anteeksi' and 'piru vieköön' are all the vocabulary you need
