It is an ancient city located in the Caria region of Anatolia. It is located within the borders of Çandır District of Köyceğiz District of Muğla province. Kaunos rock tombs are best viewed from the Dalyan district of Muğla's Ortaca district.
The city was founded on the slope of the mountainous hill around which Kalpis (Calbys-Dalyan Stream) flows. The city, which was once a port city, has now moved away from the coast due to the formation of the Dalyan Delta (Wikipedia).
