It is situated near the left bank of the river Alfeios. 1 km south of Mavria, 3 km east of Kourounios, 3 km northeast of Isoma Karyon, 3 km west of Katsimpalis, 5 km southeast of Karytaina and 8 km northwest of Megalopoli. There are lignite mines east of the village. The ancient city Trapezus was situated near the village. In 2001 Kyparissia had a population of 95.
To the east of the modern village lay the ancient town of Basilis (Βασιλίς), which had largely vanished by the 2nd century AD, when the geographer Pausanias recorded that only the sanctuary to Artemis survived. The site is now being excavated.
