Bregenzerwald, forested mountain range in western Austria. The range, part of the Allgäuer Alps, is drained by the Bregenzer Ache (stream) and has been partly deforested. Its hilly Vorderwald (foothill area toward Bregenz) supports pasture and dairy farming, while winter-sports centres and climatic health resorts in its Hinterwald (mountainous interior) make the tourist trade a major economic factor.
