The village has been labelled a "Village of Character" by the Departmental Committee of Tourism. It is a member of Les Plus Beaux Villages de France (The Most Beautiful Villages of France) Association.

The inhabitants of the commune are known as Balazucains (masculine) or Balazucaines (feminine).

For millennia Balazuc has been the site of a ford on the Ardèche river which was a Gallic stronghold. The name Balazuc comes from the name Baladunum of bal meaning "rock" and "dunum" or "fortified height" in Gallic.

Balazuc has the remains of Neanderthal men who hunted ibex there at the beginning of the last ice age. Farmers arrived in the Neolithic period around 3000 BC. to raise goats and sheep, cultivate the bottom of the depressions, and place their dead in mass graves in stone coffins.

In the Late Bronze Age, around 750 BC., the ford below the village was used. The Gauls, for whom there is no trace, gave it its name: Baladunum. The Gallo-Romans cultivated the Plain des Salles where the great Roman road passed between the Rhône and Nîmes. An early Christian sarcophagus has been found whose high reliefs include biblical scenes (a facsimile is displayed in the town hall). In the Middle Ages the village had a church and a castle from the 11th to 13th centuries in an enclosure which dates them. The castle was originally built in the 12th century and greatly enlarged in the 13th century with a square keep. The ramparts, keep, noble houses, and fortified houses are well preserved.

The village underwent an evolution of houses across the centuries but retained its originality and the medieval character of the village with its narrow streets and its "callades".

Pons de Balazuc, the son of Gérard de Balazuc, was one of the first known lords. He went on the first crusade and was killed just before the capture of Jerusalem in 1099 at the Siege of Arqa.
