In 550s B.C. the Cnidus people wanted to dig a tunnel in the narrowest land piece of the peninsula between the Hisarönü Gulf and the Gökova Gulf as a defense border against the Persians. In that way, they would make the peninsula one island and the defense would be easier. They started with diligence and put in a lot of effort; however, in the end they could not manage and the city was conquered by the Persians. For dinner and overnight stay, we will anchor at Bencik Bay.
