Rönnskärs udde

Rönnskärs udde is located about 25 km northeast of Norrtälje and about 5 kilometers east of Älmsta. Here you stand on the dividing line between land and sea. The rocky area at the far end of Rönnskärs udde is one of the most easterly landmarks along the entire Väddök coast and therefore an important area for weary small birds that have managed to cross the Åland Sea. The cliffs have been carved by ancient glaciers and on the headland you can see ice shards from different ages. A short distance off Rönnskär's headland, the sea depths soon reach 30 meters. The woodland is relatively untouched: spruce with elements of aspen, pine and birch. Here you can find the orchid knotweed, a species associated with older coniferous forests.

Most of all, Rönnskärs udde is a classic place to watch migrating birds! There is something to see here all year round: In late September and October, the southbound migration is at its most intense. This is when you can see loons, wigeons and eiders. If you visit in November or December, several species of seabirds may linger. If the winter is ice-free, you can see, for example, little auks, cormorants and long-tailed ducks on the coast. The spring migration past Rönnskär's headland begins as early as March with eiders, goldeneyes, lapwings and curlews. At the turn of April, lapwings, wood pigeons and ringed pigeons, skylarks and many other species pass by.
