Kaldar Cave is one of the archaeological sites that make the Khorramabad area important beyond its castles and bridges. Excavations have produced evidence connected with early human occupation in the Zagros, adding deep prehistoric context to a region already rich in later historic remains.
The site is best approached as an archaeology-minded excursion rather than an easy show cave. Its value lies in what was found there and in the landscape around Khorramabad, where caves, valleys, and passes have shaped movement and settlement for a very long time.
