The district was made up from combining areas from the Alappuzha, Idukki and Kollam districts. The district is part of the historical Central Travancore region of Kerala. The Central Travancore consists of the South-Central districts of Pathanamthitta and (parts of) Kottayam, Alappuzha, Idukky and Kollam.

Three important rivers, the Achankovil River, Manimala River and Pamba River flow through the district. River Pamba originates from Sabarimala and is considered a holy river.
