Tour Destination Page template

Hi, I want to have my tour destinations page template like http://travelwp.physcode.com/tour-destination/canada/ . With large header image and texts. Presently my destination page https://makemytraveltrip.com.au/malaysia/ is inheriting the layout structure for all general pages. Please let me know how to implement this type of layout for destination pages. I searched for “tour-destination” parent page, not present in the theme.
