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.

A strict protection reserve established in 1959. Subject of protection: a dystrophic lake with floating islands of peat moss Access to the lake is very difficult. I suggest leaving the bike upstairs. The path leads across a steep ravine with fallen trees (last two photos). The lake itself can be walked around, although the area can be wet at times.
