Boerne mixes its historic past and small-town ambiance with new city folk who are seeking an area where natural beauty abounds and where the quality of life and open-space environments are valued. With the expansion of Interstate 10, Boerne became even more accessible to tourists and metroplex residents and growth began to find the area. Once called the key to the hills, Boerne is situated on the east side of Interstate 10 about 22 miles northwest of San Antonio.
