Apart from the large caves, Kefallinia has also many smaller but still remarkable caves. The most famous are:
- Fiskardo: THE CAVES situated on Spiliovouno hill are sites of archaeological interest. Remains of Cyclopean walls are found in close proximity.
- Lixouri: DRAKOSPILIA (dragon cave) south of the city.
- Argostoli: AGIOS GERASIMOS CAVE, situated 3 km from the town. This is where Agios Gerasimos, the island's patron saint, led an ascetic life before settling in the Valley of Omalon.
- Sami: THE ZERVATI CAVE, located in the area of Karavomylos, is 18 m deep and 75 m long. It features two small lakes whose banks support aquatic plants that are rarely encountered in Greece. The cave is not open to the public.
- Poulata: THE AGGALAKI CAVE. It is surrounded by 14 other caves. It has a 50-m-deep cauldron-like opening, and creates a lake with a surface area of 3,000 m2 approximately, and a subterranean karst branch that extends over 8,000 m2. The cave is not open to the public.
