Pulkkilanharju Light: A Scenic Lakeland Route

Pulkkilanharju Light is more than just a tourist attraction; it's a journey through Finland's geological past and stunning lakeland scenery. This nearly 9-kilometer-long esker is comprised of ridge islands and submerged ridges, a testament to the Ice Age's powerful shaping forces. The narrow ridge traverses Lake Päijänne, offering visitors panoramic views of the surrounding waters and landscapes. The area is part of the nationally valuable scenic area and the Salpausselkä UNESCO Global Geopark, highlighting its geological significance. Pulkkilanharju is formed of materials deposited by meltwaters at the end of the last Ice Age, approximately 11,500 years ago. The esker is an important birdwatching site during spring and autumn migrations. Connected by three bridges—the embanked section of Pulkkilansalmi, the suspension bridge of Karisalmi, and the arch bridge of Käkisalmi—Pulkkilanharju offers a blend of natural beauty and human engineering. Part of Pulkkilanharju belongs to the Päijänne National Park, adding to its appeal for nature lovers. Visitors can explore the esker on foot via the Pulkkilanharju Nature Trail, a mostly easy 2-kilometer route from Karisalmi bridge, with a longer 4.5-kilometer option available. Pulkkilanharju also marks the starting point of the Päijänne Tunnel, the world's longest continuous rock tunnel, which supplies drinking water to over a million Finns in the Greater Helsinki area.
