Unspoilt means not damaged by building or crowds. An unspoilt beach, unspoilt countryside, remains unspoilt.
It is praise with a problem inside it: saying a place is unspoilt in print is often the beginning of it being spoilt. This is the British spelling; American writing has unspoiled. It usually means undeveloped rather than untouched.
