The Adventure Park at Mosfellsbaær The adventure park in Ullarnes Breweries for the whole family is loaded with exciting games created by the Boy Scout Company Mosverjar. There are many climbing and pedaling equipment along with a rocking runner that can swing. There is also a climbing net in the middle of the park, near the sports field, which is popular with young people. In the fall of 2013, handicrafts were created by the handicraft workshop Ásgarður to celebrate Mosfellsbær on the occasion of the twentieth anniversary.
