Lake Rusałka

Lake Rusałka (roughly "roo-SOW-kah") is a wooded reservoir on the western edge of central Poznań, about 4 km from the Old Market Square. Locals come here to swim in summer and to walk, run and cycle the lakeshore loop the rest of the year. It is one of the easiest nature escapes in the city — but it also carries a dark World War II history that makes a visit more than just a stroll in the woods.

Where it is and why it matters

Poznań sits in western Poland, roughly halfway between Berlin and Warsaw (about 2.5–3 hours by train from either). The city's green "wedges" run from the outskirts toward the center along small river valleys, and Rusałka lies in the western one, along the Bogdanka stream, between the districts of Sołacz, Golęcin and Wola. Poznań-Ławica airport is about 7 km from the city center.

A lake built by forced labor

Rusałka is not a natural lake. During the German occupation, work began in May 1941 to dam the Bogdanka, and it took about 16 months. The labor was done by Poles and Jews held in forced-labor camps in Poznań; gravestones from the demolished Jewish cemetery on Głogowska Street were used to line the bottom. The Germans called the reservoir Elsensee after a nearby mill. After the war it was renamed Rusałka, after the water nymphs of Slavic folklore.

The surrounding forest is also a memorial landscape. In January 1940 the SS executed prisoners from Fort VII — one of the first Nazi camps in occupied Poland — in these woods. Three monuments on the north, south and east shores mark the sites; the eastern one commemorates about 2,000 victims.

Things to do at Lake Rusałka

• Walk the loop — a trail of about 3.5 km circles the 36.7-hectare lake. Allow about an hour.
• Swim in summer — the north shore has had a beach since 1960. Today the lifeguarded bathing area is run by the city sports agency POSiR (27 Golęcińska Street) and includes beach volleyball courts and an outdoor gym. It operates only in high summer (in 2025: June 7 to September 6).
• Fishing — popular with local anglers; zander (pike-perch) is the main catch. Night fishing is not allowed.
• Movie trivia — the lake stood in for the Dnieper River in the Polish epic With Fire and Sword (1999).

Is it worth visiting?

If you have a spare half-day in Poznań and want greenery rather than museums, yes. In autumn and winter the beach is closed but the trail stays open and free, 24/7. Don't walk on the ice: the lake is shallow (average 1.9 m) but fed by streams, so the ice can be unreliable. Signage is in Polish; the route is easy to follow without it.

How to get to Lake Rusałka

By public transport, take a tram to the Ogrody stop, then walk about 20 minutes along Botaniczna Street to the trail on the south shore — check current routes with ZTM Poznań or the Jakdojade app. Tickets are paid in PLN (złoty). Cyclists can follow the Bogdanka valley from Sołacki Park. Drivers can reach the beach via Golęcińska Street, but parking fills up on hot summer weekends.

Nearby

• Adam Mickiewicz University Botanical Garden — a short walk from the south shore.
• Sołacki Park — a historic park along the Bogdanka.
• Lake Strzeszyńskie — the source of the Bogdanka, a few kilometers northwest.
