Ahl Plantation is a coastal forest planted in the later part of the 19th century on a large depositional protrusion southwest of Ebeltoft and comprise both salt marsh and woodland. The sturdy mountain pine dominate the 110 ha forest, but oak and birch is mixed in. Green woodpecker is common here, indulging in the many ant-heaps of the forest. The northward shores are very shallow and attracts flocks of foraging gulls and wading birds such as lapwing, curlew, oystercatcher and ringed plover. Some of the trenches and bunkers built here during the war of 1801–1814 against England, can still be seen today. Similar constructions exists at Ebeltoft, Havmøllen at Jernhatten, Randers and Stavns Fjord on the island of Samsø.
