Tillenberge, Nature reserve in Nordhorn, Germany

Tillenberge is a nature reserve near Nordhorn featuring hardwood forests, oxbow lakes, and inland dunes along the Vechte River. The area contains multiple habitat types and transitions between wet zones near the river and dry sandy areas.

A roughly 16-hectare Tillenberge area was designated a nature reserve on 14 November 1936. It was absorbed into the larger "Brandlechter Vechtetal und Tillenberge" reserve, protected from 21 July 2001. In 2018 the regulation was redrawn and the site was renamed "Tillenberge" on 19 April 2018, nearly matching the 2004 FFH area.

Since early 1996, around 20 hectares of the Tillenberge dunes have been tended by Nordhorn Animal Park. To stop the heath from being overgrown by scrub, Bentheimer Landschafe sheep graze the area. Visitors may walk only on marked paths, following a visitor-guidance scheme.

The site is accessible through marked trails and offers good conditions for walking and observing wildlife. NABU Grafschaft Bentheim provides additional information and organizes guided visits for visitors.
