The Hahnheide is a nature reserve in the east of the municipality of Trittau in Schleswig-Holstein.
The Hahnheide is a vast forest area, here are over 100 year old trees and there are small lakes. For an extensive walk, the Hahnheide is just right, there are several hiking trails that lead through the yet rather hilly landscape. For those who like to observe animals, the natural forest of the Hahnheide is an exciting place, because in this specially protected part of the forest live, among others, bats, crested newts and eagle owls.
