Sipoonkorpi's National Park was established in 2011. It covers an area of 23 km² and spreads to the Vantaa, Sipoo and Helsinki areas. Sipoonkorpi is one of the last undeveloped environments in the Finnish capital region along the Nuuksio's lake plateau.
There are various forests, bogs and cultural landscapes in the area of Sipoonkorpi's National Park. The terrain is variable in the area and the height differences are large. Forests are hexagonal in many places, and in addition there are plenty of fresh grove-like fabrics and rock forests. The River Byabäcken flows through the park area.
