Wietzepark, Recreational park in Langenhagen and Isernhagen, Germany

Wietzepark is a large recreational park spanning across Langenhagen and Isernhagen, featuring walking and cycling paths alongside a lake for swimming. The green space combines quieter woodland trails with more active leisure areas.

Work on the Wietzepark began in autumn 2000 on about 30 hectares of farmland west of the Wietze in Langenhagen. Isernhagen joined the project in 2001 with a similar area east of the river, where construction started in 2004 and the park opened in 2005. The Langenhagen section was largely finished by 2006, and two 11.5-metre bridges built in 2004 and 2005 link the two halves.

The park owes its name to the Wietze river that flows through it, creating a natural thread connecting the two towns. Local residents use the green space as a gathering point for weekend outings and outdoor recreation.

The park is reached from Langenhagen and the Isernhagen hamlet of Niedernhägener Bauerschaft. Car parks and two bus stops lie in the southern section. Two 11.5-metre foot and cycle bridges, built in 2004 and 2005, link the Langenhagen and Isernhagen halves across the Wietze. The park lies on Route 9 of the Hannover cycling region.

The Hufeisensee is up to 20 metres deep and was formed by gravel extraction, not mining; gravel was still being extracted in its northern section outside the bathing season until 2014. The rope course on its western shore opened in spring 2012.
