No good oppotunities close. There is an indoor ski center in the suburb Roedovre http://www.isgk.dk/ or you might try this possibility 110 km from Copenhagen (in Sweden) http://www.vallasen.se/. I have not tried any of these possibillities myself though. almost 9 years ago
One little fact about Denmark. The are NO mountains,,, not 1! In fact the tallest peak in Denmark is called "heaven/sky mountain" and is technically classified as a hill!
Danes go to Sweden, Norway and The Alps to go skiing, and the skiing is good there. In fact, Denmark only gets a light sprinkle of snow (by most ski area standards)... The last two years this has not been the case, however, there are still no out-door ski resorts inside Denmark. The nearest is an area on the Swedish/Norwegian border, the name slips me by. I'm sure I read someone before me had mentioned it. I've heard it is a party area and can get "crazy-with-snowboarders"... If you are with family and children I recommend places in Norway, such as Lillehammer (host to the 1994 Olympic winter games)... Where prices are not as inflated as The Alps (Switzerland, France Italy, Austria)
