The landscape here harks back to olden times farming with the reclaimed fields, meadows, fields, hazelnut bushes and old crowned sparbank seeds. In the spring you can see the orchid Adam and Eve flower. The beaches on the island are rocky in several places and drop dramatically into the sea.
The three nature reserves Kråmö, Bokö-Oxnö and Bokö-Askö form a connected archipelago area south east of Trosa. This nature reserve is different to the others with both old farmland, forest areas and an area with holiday cottages.
