Bornholm has both varied natural features, such as Almindingen,
Hammeren,
Jons Kapel,
Paradisbakkerne, and
Dueodde, as well as
Denmark's tallest lighthouse. Places of interest in Almindingen include the ruins of
Lilleborg Castle, the Kristianshøj Inn, well built forest ranger residences, the
arboretum, Bolsterbjerg,
Gamleborg, and to the east, the hills of
Paradisbakkerne. Towers for bird-watching are erected to view birds of prey, ducks, geese and sometimes large cranes. The Nexø-Dueodde tourist information office provides information to tourists. There are four designated walks: • Walk 1 is long. • Walk 2 is long. Along the Ekkodalen echo valley, the echo can be best heard by walking along the marked path to the left and facing H.C. Ørsted's spring. At Rytterknægten, the monument erected in 1856 is seen. The viewing tower here made in 1899 from where panoramic views of the forests can be enjoyed is tall. • Walk 3 is long. There is a diversity of trees, shrubs, grasslands and some small lakes. The Arboretet, landscaped in 1932 by the forest ranger A.F. Valdemar Seier (from 1916 to 1946), covers an area of 4-5 ha. • Walk 4 is long. There are several lakes such as the Græssøen, Dyresøen, Borgesøen, and Gamleborg Lake. Other notable landmarks are a Viking era castle ruin and Lilleborg Castle. ==See also==
