Avnø Nature Centre opened in 2004 in buldings that used to house the military school of aviation.
The former control tower offers a gret view of seals basking on stones and reefs in Avnø Fjord together with a large number of ducks, waders and mitrating birds.
Today, the area is dedicated to a Nature School that offers nature guiding as well as accommodation; two open wooden huts in the forest ’Nokkeskoven’ are at the free disposal of guests. Paths lead to the best spots for watching seals and birds, and if you take a look into a waterhole you are likely to find rare apmhibians.
