Billudden, Nature reserve in Uppsala County, Sweden
Billudden is a nature reserve spanning about 1,930 hectares that extends into the Baltic Sea, featuring sandy beaches, limestone pine forests, and extensive seabuckthorn thickets. Two marked trails wind through different habitats across the property.
The area developed as a fishing village called Billhamn around a natural harbor formed by meltwater from the last ice age. It was later protected to preserve both its natural features and traces of early settlement.
Two educational trails guide visitors through the diverse habitats and show typical plant formations of northern Europe. As you walk through different sections, you discover the rare fungi species that thrive in these forests.
Parking areas are available near Rullsands camping, and a bus stop sits about 600 meters from the main entrance. The approach road is asphalt, making it easy to access.
The land continues to rise from the sea as the earth's crust slowly rebounds after the last ice age. This process constantly creates new shorelines and expands the reserve's territory year after year.
