Copenhagen Free Walking Tours offers a range of fun, informative tours so you can explore Copenhagen by foot. From exploring the historic landmarks on the Grand Tour to delving into the alternative side of the city on the Christianshavn Tour, there's something for everyone. I have personally been on several of these tours and love to do them whenever we have visitors! I have marked this as "budget" instead of "free" because you are expected to tip your tour guide at the end.
