The ahupua'a consists of Kalihi Uka, Kalihi Waena and Kalihi Kai.

Kalihi was also known for its fishponds, ʻĀpili, Pahouiki, Pahounui, ʻAuiki, and Ananoho, near the present Sand Island Access Road (Route 64) all of which have since been filled in. The harbormaster of Kamehameha I, Captain Alexander Adams, maintained a residence near the ʻĀpili pond.
