There were no people missing but authorities had air and sea assets in the area and were conducting a search as a precaution, in case people were trapped under the rocks, one official said.
There were at least seven people injured in the rockfall, but according to coastguard officials, none of them received life-threatening injuries.
Witnesses said a large rock fell from a cliff into the sea at Navagio, known as Shipwreck Beach, creating a large wave that capsized small boats, local media reported.
One foreign woman was injured and transported to hospital, the coast guard said, adding that the beach was evacuated and boats were banned from approaching the cove until further notice.
Video footage of the terrifying moment showed the rock from the limestone cliff face split and plummet to the shore, sending waves crashing over tourists.
Small boats are capsized after a landslide occurred at the popular beach of Navagio, or Shipwreck Beach, on the western island of Zakynthos, Greece, Thursday, Sept. 13, 2018. The woman's husband and two children were hospitalized with minor injuries.
Rescue crews with sniffer dogs were searching the beach on the Greek island of Zante last night for possible victims following the huge landslide. Authorities later said everyone who had arrived at the beach on tourist boats had been accounted for.
