With the efterårsferie (autumn school holiday) starting at end of school on Friday 13th (spooky) there is plenty to keep the kids entertained over the break. Tivoli opens for Halloween that day and the park will no doubt be festooned with spookiness and pumpkins. 
Culture Night kicks of the autumn school holiday and shouldn’t be missed.
Lego building at the Danish Architecture Centre (remember to book yourself a place if you want to come in with your child).
Louisiana has events for children in the Children’s Wing
Frilands Museum is a great autumn trip and they have stuff going on during the week
Renaissance Fair is taking place at Kronborg Castle in Helsingør if you fancy a trip further afield
Viking for a day at the Viking Ship Museum in Roskilde sounds like fun Workers’ Museum http://www.arbejdermuseet.dk/arrangement/efteraarsferie-skaeg-stauning/
Climate Planet is the huge planet installation in the Rådhuspladsen and sounds amazing.
Looking for a pumpkin patch then this post from another local blogger helps. Anya also mentions places for apple picking, which is more of an Autumn tradition in Denmark.
Enjoy the holiday!
