The Hill Country encompasses the region west and southwest of Austin and north of San Antonio. The distance between these two gateway cities is 60 mi. Interstate 35 marks the eastern border, while San Antonio's State Loop 1604 notes the southern limit. The northern border is ambiguous, but generally includes everything south of Lake Buchanan and along Highway 29. The western border is also open to interpretation, but is best followed along U.S. 83 from Junction to Uvalde. More »
