(Undated) -- National parks around Colorado and the rest of the nation won't have entry fees today. It's in celebration of the 98th birthday of the National Park Service. The park service says while entrance fees, commercial tour fees and others will be waived, there will still be fees for reservations, camping and other amenities. Participating parks include Great Sand Dunes National Park and Preserve, as well as Rocky Mountain National Park.
