The district of Aegidienberg encompasses the parts of Bad Honnef located east of the Honnef urban forest, in other words east of the Siebengebirge. In geographic terms, the area forms part of the Asbach plateau in the foothills of the Niederwesterwald. The various parts of the district are distributed across hills which all lie within the broader boundary of the Siebengebirge Nature Park. The Siebengebirge itself, with its peaks up to in height, separates Aegidienberg from Bad Honnef, which is about away in the Rhine Valley. Aegidienberg is located at an average altitude approximately above Bad Honnef. The two are linked by Landesstraße 144 through the long Schmelz Valley.
