Around the year 1,000, the site of the karst spring in the Deister Gate is mentioned in a description of the boundaries of the Bishopric of Hildesheim under the name Helereisprig.

The Haller forms the boundary between the Bishoprics (now Dioceses) of Hildesheim to the south and Minden to the north.

The B 217 from Hanover to Hamelin, a Landstraße, two farm and forest tracks, the Hanover–Altenbeken railway, carrying S-Bahn line 5 from Paderborn via Hamelin and Hannover Central to Hanover Airport, and the upper reaches of the River Haller run through the pass.

Nearby is a forest track through the woods which cuts through the Bückethaler Landwehr, which is described here on an information board.

The forest inn, Deisterpforte, was built in 1876 by the Ratskeller publican, Christian Bauer, on the edge of Springe as a daytrippers' destination; it is still in operation.
