Erlenbach lies at the foot of the 317 metre tall Kayberg in the lower Sulmtal (valley of the river Sulm) in the eastern part of district of Heilbronn.

During the population growth and resulting construction activity after World War II, Erlenbach and Binswangen have grown together to form a single village.

The Catholic parish St. Martinus in Erlenbach was rebuilt between 1753 and 1760 in late Baroque style on the site of an older Martinskirche.

The Catholic parish St. Michael in Binswangen was built by Ludwig Bronner in 1788 on the site of a 1578 predecessor and was dedicated in 1818.

There are two annual wine festivals: During Mardi-Gras, the Binswangen Carnival Club puts on a parade and variety show.
