Nature reserve Mewia Łacha

Mewia Łacha is a nature reserve at the mouth of the Vistula River where it enters Gdansk Bay, featuring wetlands, meadows, and sand dunes that create multiple habitats. The area spans across Sobieszewska Island at a point where fresh and salt water environments meet.

The area was protected in 1991 to safeguard a crucial migration route for birds traveling along the Baltic Sea coast. Since its establishment, it has served as a vital stopover for species moving between northern and southern regions.

The reserve is a gathering place for bird watchers who come during migration periods to observe species rarely seen elsewhere in the region. It has become an important destination for people interested in ornithology and nature documentation.

The best time to visit is during the spring and autumn migration periods when most bird species are present in the area. Visitors should stay on designated paths and observation points to avoid disturbing nesting sites, especially between April and July.

The lagoon is home to an unusual assembly of seals, including grey, harbor, and ringed seals that coexist where fresh and salt water meet. This gathering of three seal species in one location is seldom seen and adds to what makes the place remarkable.
