Crossing the Polish-Lithuanian border. At this point, the gravel road ends and the asphalt begins. Driving through here, you can circle Lake Gaładuś, which lies along the border. Right next to it (on the Polish side) runs the R65 Suwałki Region Cycle Ring trail. Just before the border, on the right, there's a path to the lake.

Lake Gaładuś, partially located in Lithuania, is one of the most beautiful bodies of water in the Suwałki Region and a true gem of the Sejny region. Its elongated shape, with bays, headlands, and islands, creates an exceptionally picturesque landscape. The lake's shores are high and hilly, covered with meadows and small forests, providing stunning views during stops or short breaks. The waters are of high purity, and the bottom is sandy and rocky, ideal for swimming on warm days.

Lake Hołny in the Sejny commune is a picturesque reservoir covering over 150 hectares, located right on the border with Lithuania. Thanks to its quiet zone, it offers a peaceful atmosphere, and the industry-free environment encourages relaxation close to nature. The shores are largely covered with dense reeds and rushes, which limits access but gives the lake a wild character. It's an interesting stop on the trail, especially for those seeking peace, solitude, and contact with nature.

Before the start of Operation Tempest in 1944, the Home Army districts of Augustów and Suwałki had a total of almost 5,000 soldiers. On May 12, 1944, the inspector of the Home Army in Suwałki, Major Franciszek Szabunia “Zemsta”, and the commander of the Soviet unit operating in this area, Major Włodzimierz Cwietyński “Orłow”, signed a cooperation agreement. In addition to fighting the Germans, the Orłowo unit conducted reconnaissance on the structures and number of Home Army units. As a result of the partial exposure of the Home Army during Operation Tempest, the Soviets arrested about a thousand people in late 1944 and early 1945. In February, the transformation of the AK structures into the AKO began, and in the spring of 1945, underground activities against the institutions of the emerging communist system resumed.
