Best moderate trails in Hillesheim

Nice tour past several former volcanoes - most of them have already been dismantled or will be. From the southern outskirts of Hillesheim (am Lier) on the old Roman road across the Kyller Höhe to Goßberg. Along the edge of the forest to Walsdorf and further into the Arensberg - a mined hollow volcano. From the Arensberg to the northwest (view of Kerpen Castle) and over the Schwalbenhof to Berndorf. There up to the fortified church. Past the Mahlberg to the Swedish ski jump above Hillesheim...
