An aerial search was is also underway for Calibet. The tourist is “well-known on the island” due to numerous visits over the course of the past few years, Calliope Despotidi, the deputy mayor of Amorgos, told the Greek Reporter.

Authorities have been attempting to track Calibet’s phone, and are also using drones to help facilitate the search. Calibet was last in communication with his sister on Tuesday when he sent her a photo of a trail sign, per the Greek Reporter. He was reportedly supposed to meet with a friend between noon and 1 p.m. local time, but never showed up.

Officials believe that Calibet deviated from his original hiking route, which was expected to take a travel time of just over four hours.
