There is no specific name for a travel documentary. Rather, the travel documentary is simply an offshoot of the genre of documentary filmmaking, specifically dealing with issues relating to travel. The interest of many travel documentaries is in chronicling road trips and excursions abroad for the entertainment and research of those who cannot otherwise go to the place in question themselves for whatever reason. There are, however, plenty of other documentaries in this vein that instead seek to touch on something a little deeper. Nowadays, a travel documentary seems lost without at least mentioning in passing the detrimental effects of climate change and global warming on the climate of exchange between people and their natural environment.
