wheat and grass seed. The northern side of the sound is flanked by 25 km of border hills down to the lakebed contributing to the characteristics of the landscape. The sound is drained by two pumping stations lifting the water up into a Northern Canal which flows into a river that runs through the centre of the town, Grenå, before entering the sea, between Grenå’s marina and seaport. Kolind Sound lies 2 metres below sea level, while the pumping elevation at the pumping stations is 5 metres. The sound is flanked by canals that are popular among anglers. Sea trout is a particularly common catch, as are pike, perch and bream. Southern Djursland South of Kolind Sound lies a sandy ice-age floodplain housing Djursland's airport, Aarhus Airport, which serves Denmark's second largest city, Aarhus (pop. 319,094), 41 km southwest of the airport. Mols: Going further south one enters an area with the most abrupt hills in Djursland, the Mols Bjerge, ending at the bights and inlets of southern Djursland. Mols contains Mols Bjerge National Park, which includes coastlines, parts of seabed, the town of Ebeltoft, and a hilly non-farmed landscape with views over the bights and inlets of southern Djursland. The non-farming part of the park is maintained as an open post-ice-age landscape. This is done by grazing and cutting down excessive tree growth that would otherwise cause natural, and dense, forestation, obstructing views and accessibility. The national park was established in 2009, mostly on privately owned land. Establishing the park did not involve buying or expropriating land, but an intention to strengthen information about nature-related issues in the area, and to widen use and access to the park. The main bays, bights and coves on southern Djursland are the Bay of Aarhus, the Bight of Begtrup, the Bight of Knebel, the Bight of Egens and the Bight of Ebeltoft. Northern Djursland The area north of Kolind Sound (Kolindsund), 15 km north up to the coast, consists mainly of low hills with predominantly sandy soil that is quite good farmland. Northern Djursland is the most forested and least inhabited part of Djursland. Randers Fjord: The northeastern corner of northern Djursland is bounded by Randers Fjord, a long and narrow outlet through which Denmark's largest river, the Gudenå, enters the Kattegat. The land bordering Randers Fjord is in some places marshy plains covered in reeds, which to some extent are cut
