Borrehaugene is Norway's first National Park and has the largest Viking graveyard of Scandinavia with significant discoveries from ancient times.
The Midgard Center has all available information on the seven big barrows as well as 30 smaller barrows and graves. Legend tells that in the early mornings, while morning dew still rests over the meadow, you can hear the elves play on "The fiddler's mound" (Spelemannshaugen) on the vicarage field.
Borrehaugene can offer many magic tales from historic times. Just below Borrehaugene is the Borre beach and the coast path, leading all the way to Åsgårdstrand.
The Borre lake is a popular resort area for walks and outdoor activities - Try your fishing luck and catch a pike (so ugly that a tourist thought it looked like a crocodile), or meet a deer, moose or beaver, if you are lucky.
The Adal tower and the Adal castle are reckoned to be among the most significant castle remains of the Vestfold County. Løvøya, situated on the way out of Horten northbound, is a scenic, very popular leasure time resort for the local population as well as tourists, offering a huge camping site and several small beaches. The Løvøya chapel and the St. Olav's well are worth exploring.
