The summit of Mount Olympus was first reached on the 2nd of August 1913 by the Swiss Frederic Boissonnas and Daniel Baud-Bovy, aided by Christos Kakkalos, a wild-goat hunter from Litochoro. Kakkalos was the first of the three to climb Mytikas and later served as the official guide on Olympus until his death in 1976.
