Boondocks

Rural place; more intense word than 'backwoods', or 'woods' or 'hinterland'.
The word comes from Philippino language, in which it means mountain. When American occupied the land towards the end of 19th century, they used this word to denote the mountainous hinterlands in Philippines.

Example
One of the few drawbacks to living out in the boondocks is that public services, such as litter collection, are less available than they are closer to the city.
