Lake Hańcza, where the pier is located, is the deepest lake in Poland, reaching a depth of 108.5 meters.
The lake is classified as a mesotrophic body of water, noted for its exceptionally high water transparency compared to other Polish lakes.
The pier is a popular training site for scuba divers due to the steep underwater drop-offs characteristic of the glacial basin.
The region surrounding the beach is part of the Suwalski Landscape Park, which was the first landscape park established in Poland in 1976.
Geologically, the lake basin was formed by the erosion of a glacier during the Vistulian glaciation.
The Beach and Pier in Błaskowizna is situated on the eastern shore of Lake Hańcza, the deepest lake in Poland and the entire North European Plain. The site features a wooden pier extending into the glacial lake, providing access to clear, cold water known for its high transparency. The surrounding area is part of the Suwalski Landscape Park, a region defined by post-glacial moraine hills. The beach area consists of a mix of sand and grass, serving as a primary point for swimming and scuba diving. Lake Hańcza reaches a maximum depth of approximately 108 meters, making it a destination for deep-water diving enthusiasts. The site is a key entry point for exploring the Czarna Hańcza river valley and the rugged terrain of the Suwałki region.

Wear water shoes, as the shoreline and lake bottom in this region are often rocky due to glacial deposits.
If planning to swim, be aware that the water remains cold even in summer due to the lake's extreme depth and minimal surface warming.
Bring polarized sunglasses to better observe the lake's depth and clarity from the pier.
Attempting to swim long distances from the pier without a boat escort, as the water temperature drops rapidly with depth.
Most accessible during the summer season; parking areas may be restricted or snow-covered during winter months.
Maintain silence as the area is part of a protected landscape park; respect the no-littering policy to preserve the clarity of the lake.
