Argolida area has few but very remarkable caves. Some of those are:
- Didyma: Two CAVES (of doline karst) are found just before the entrance of the village (1 km to the W). The largest cave has a diameter of 150 m and reaches a depth of 80 m. Both caves are truly impressive in terms of size and shape.
- Kilada: FRANCHTI CAVE with important paleontological findings.
