The island's isolation has created a distinct wildlife community. Notable residents include grey seals that frequent the shores, particularly during breeding season. The forest hosts populations of mountain hares and hedgehogs, while the airspace above is dominated by various seabirds including eiders, guillemots, and rare species like the Caspian tern. Notably, the island lacks large predators, allowing smaller species to thrive. Insect life is particularly rich, including several rare beetle species found nowhere else in Sweden.
Despite its sandy terrain, Gotska Sandön supports a diverse array of plant life adapted to its unique conditions. The island's interior features one of Sweden's most pristine old-growth pine forests, with trees dating back 200 years. The coastal areas showcase specialized dune vegetation including marram grass, sea holly, and rare orchid species. The island's plant communities form distinct zones from beach to forest, demonstrating remarkable adaptation to wind and salt exposure.
The island formed during the last ice age when glacial deposits created a massive sand ridge. This geological foundation continues to shape the landscape through ongoing aeolian processes, with wind constantly reshaping the extensive dune systems. The island consists primarily of fine-grained sand and features impressive dunes reaching heights of up to 42 meters. This dynamic environment creates a unique ecosystem where the landscape is in constant flux, with dunes slowly migrating across the island.
First documented in medieval sailing records as 'Sancte Andree ø', Gotska Sandön has a rich maritime history spanning centuries. The island served as both a haven and hazard for sailors, with numerous shipwrecks along its shores dating from the 1600s to the early 1900s. A lighthouse was established in 1859 to improve navigation safety, and the island has hosted a small community of lighthouse keepers and forest workers. In 1909, it was declared a national park, making it one of Sweden's oldest protected natural areas.
The island's most striking features include the Bredsandsudde lighthouse, standing sentinel since 1859, and the dramatic dune landscapes that encircle the island. The 'Kapellänget' chapel site offers historical interest, while the pristine beaches stretch for 42 kilometers around the island's perimeter. Unique geological formations include 'Höga Land' - the island's highest point - and the distinctive crescent-shaped dunes. The old lighthouse keeper's residence now serves as a museum, offering insights into the island's maritime heritage.
Gotska Sandön experiences a maritime climate moderated by the Baltic Sea, with milder winters and cooler summers than the mainland. Average summer temperatures range from 15-20°C (59-68°F), while winters typically hover around 0°C (32°F). The island receives less rainfall than the Swedish mainland, averaging 500mm annually. Strong winds are common year-round, contributing to the island's dynamic dune landscape. The most pleasant visiting conditions occur between May and September, though each season offers unique natural spectacles.
