The approximately 75-hectare nature reserve „Aper Tief“ is located south of the river of the same name between Apen and Augustfehn in the Ammerland district. Through a spectacular dike relocation in 2005, a unique, tide-dependent floodplain landscape with the only freshwater mudflat in the northwest was created here.

Aper Tief The Aper Tief is a natural river in the municipality of Apen. Coming from the east, it flows through the farming communities of Hengstforde, Vreschen Bokel and Holtgast, from where it merges into the Jümme. Two retention areas were created along the river, which have become a fantastic nature reserve. The connection of the Aper Tief with the Jümme, Leda and Ems as far as the North Sea means that the tides are noticeable in this area with a tidal range of 60 to 120 cm. While hiking or cycling, discover the freshwater mudflats in Hengstforde and the floodplain landscape in Holtgast with its diverse birdlife. Anglers will also find excellent conditions here.
