The northern boundary of the Frickenhofer Höhe and its spurs is the lowest reaches of the Fichtenberger Rot, a river that approaches from the west and empties into the River Kocher near Gaildorf-Unterrot. The other boundaries, running anti-clockwise, are the Gschwender Rot and its two headstreams, the Lein and Kocher. The Gschwender Rot flows out of Gschwend southwards through the small villages of Birkenlohe, Hönig and the Rehnenmühle Retention Basin to its mouth on the Lein in Täferrot and demarcates the range to the west where it adjoins the Welzheim Forest. The Lein initially rns to Heuchlingen in an easterly direction. It forms the southern boundary as it heads northeast to its mouth on the Kocher in Abtsgmünd, separating the range from the Welland. The left side of the Kocher valley from Abtsgmünd via Sulzbach-Laufen to Unterrot is its most prominent dividing line with the Limpurg Hills.
