The rugged cliffs of Heligoland's guillemot cliffs are home to large populations of guillemots, kittiwakes and gannets. Every year in June, visitors experience a breathtaking natural spectacle there - the guillemot jump.
The Lummenfelsen of Heligoland magically attracts nature lovers and birdwatchers. With an area of about 1 hectare, the red mottled sandstone rock is Germany's smallest nature and bird sanctuary.
Nevertheless, it has the highest density of breeding birds in the country. Thousands of guillemots, kittiwakes and gannets live and breed among the jagged cliffs and crowd the narrow ledges. However, Guillemot Rock is also home to fulmars and razorbills. All of these seabirds are found only on Heligoland throughout Germany.
