Lake Gardno

Lake Gardno is a large, shallow coastal lagoon in Słowiński National Park on Poland's Baltic coast, separated from the sea by a narrow sandbar where the village of Rowy sits. Reedbeds, wet meadows and the forested hill of Rowokół frame the water, and the lake is an important breeding and resting area for waterbirds on migration routes. For visitors it means quiet walks, birdwatching and some of the best views on this part of the coast.

Where is Lake Gardno?

Gardno (say "GARD-noh") lies between Rowy and the village of Smołdzino, home of the national park headquarters, roughly 110 km west of Gdańsk as the crow flies. The nearest rail hub is Słupsk; from there buses and roads lead north to Rowy and Smołdzino. Gdańsk Airport (GDN) is the closest international airport.

Key facts

• Area: about 2,468 ha (around 9.5 square miles), the park's second-largest lake after Łebsko.
• Maximum depth: just 2.6 m.
• The Łupawa River flows through the lake to the Baltic at Rowy; in winter storms, seawater can flow back into the lake.
• Słowiński National Park is a UNESCO biosphere reserve (since 1977) and a Ramsar wetland of international importance (since 1995).

Nature and protection

The lake is surrounded by strictly protected zones — Gardnieńskie Lęgi, the Mierzeja sandbar, Lake Dołgie Małe and Stone Island (Wyspa Kamienna) in the lake itself. On a polder near Gardna Wielka, park staff periodically flood the meadows to restore breeding habitat for wetland birds, which is why some paths close seasonally. Stay on marked trails: walking off-trail is not allowed anywhere in the park.

Things to do

• "Gardnieńskie Lęgi" nature trail (about 5 km) from the village of Gardna Wielka to a bird-viewing platform over flooded meadows; part of the loop closes during the March–June breeding season.
• "Rowy" nature trail (7 km) from the park's museum branch in Rowy, passing a viewing pier on the lake before heading to the beach.
• Rowokół hill (about 115 m) with a viewing tower overlooking the whole lake and the sea.
• Birdwatching — bring binoculars.

Rules and safety

Paddling across the lake to Rowy is prohibited: the eastern part is strictly protected, and the shallow water whips up dangerous waves in wind. In 1948, overloaded boats capsized here and 25 people, mostly teenage girl scouts, drowned. Fishing requires a park permit.

Practical information (as of October 2026)

• Tickets: national park entry fees (10 PLN, reduced 5 PLN) apply on selected trails from May 1 to September 30; outside that period entry is free.
• Rowokół tower: from October 1 to April 30 open only to pre-booked groups of 10 or more on weekdays. The stairs up Rowokół are currently closed; use the approach from Smołdzino.
• Bird flu: the park has reported a case in the Rowy area — avoid contact with wild birds.
• Dogs: banned in strictly and actively protected zones.

Is it worth visiting?

Yes, for nature lovers and photographers, especially at dawn or in spring and fall. Combine it with Rowy beach and the national park's famous moving dunes near Łeba.
