The district of Northeim contains more than 20 designated nature reserves, which are protected areas safeguarding unique landscapes and ecosystems. This collection focuses on three specific reserves known for their biodiversity, particularly as habitats for numerous bird species, and offers a network of routes for outdoor recreation.
This page aggregates routes and information for three key nature reserves. These include Polder I Im Hochwasserrückhaltebecken Salzderhelden, a vital bird sanctuary in a flood retention basin, and the adjacent Natural Park Leineniederung Salzderhelden with its extensive riverside grasslands. Also featured is Ahlewiesen, located within the Solling-Vogler Nature Park.
The primary activities are hiking, touring cycling, and mountain biking, with over 400 routes available across the featured reserves. The flat, open landscapes of the Leine lowlands are well-suited for cycling, while the forested areas offer varied hiking trails. The wetlands are also noted for birdwatching, with observation towers available in some areas.
The Ahlewiesen reserve is located in the Solling-Vogler Nature Park and features varied terrain. The landscape includes stream valleys, meadows, and dense forests. This mix provides a range of conditions for hiking and mountain biking routes.
This 523-hectare reserve is a dynamic waterscape shaped by the Leine River and managed floods. Its landscape consists of extensive wetlands, wet meadows, and artificially created lakes. This environment makes Polder I Im Hochwasserrückhaltebecken Salzderhelden a nationally important breeding and resting area for migratory birds.
Yes, there are more than 150 designated hiking trails across the three featured reserves. Polder I Im Hochwasserrückhaltebecken Salzderhelden offers around 60 hiking routes through its wetlands. The Ahlewiesen reserve provides over 50 trails through its forested and meadow landscapes.
