Horreby Lyng

At approximately 150 hectares, Horreby Lyng is the largest raised bog in Guldborgsund Municipality and one of the largest remaining raised bogs in eastern Denmark. The bog is designated as a Natura 2000 site and has been protected since 1981, built up from peat mosses with rare raised bog flora: royal fern, bell heather, bog rosemary, cranberry and the insect-eating round-leaved sundew grow here, and 11 bat species have been recorded in the area. During the First and Second World Wars the bog was heavily exploited for peat cutting — Nykøbing F's sugar factory extracted up to 6,000 tonnes of peat per year. An EU LIFE-funded nature restoration project from 2013–21 has closed drainage ditches and restored the bog's water level. Today there are wooden walkways over the wettest sections, a nature room with an exhibition about the project's results and the bog's cultural history, and a viewing platform — on the drier edges you may encounter common adders.
