View of Tromtöfjärden from Tromtö Nature Reserve

Tromtö Nature Reserve is located on a cape at Tromtöfjärden between the road to Hasslö and Nättraby in Ronneby municipality. The nature reserve consists largely of old oak and beech forest and is 1,242 ha, of which 374 ha is land area and begins at Hjortahammar's grave field on the road to Hasslö. The peninsula has been part of the manor landscape that belonged to the Johannishus estate. The nature reserve is rich in insects, including oak beetles and wood fungi, some of which are rare, such as saffron crocus, torticollis and sea crocus. At the outermost cape, Tromtö nabb, there is a beautifully situated natural harbor with floating docks and space for over 40 recreational boats. The harbor is run by Karlskrona Navigationssällskap.
