Oprah Winfrey, Gayle King, Julianna Margulies and other celebrities enjoy Sicily

The A-listers were guests of David Geffen.

The former music mogul's boat was docked in Sicily near Google's invitation-only summer "camp" at the Verdura Resort, according to The Observer.

"Great meal," Geffen wrote in a caption.

According to photos posted last week by King, 62, a few guests even decided to hike on an Italian trail.

"The hiking version of words with friends in Italy! We all survived," she quipped in a caption.

"Yes. I am standing. Kevin Durant," Geffen joked in a caption next to the 6'9" professional basketball player. "Google Camp, Sicily."
