On 28 July 1913, the Swiss Daniel Baud-Bovy and Frédéric Boissonnas reached the place Litochoro (about 400 m). They hired the lumberjacks Christos Kakkalos and Nikos Bistikos to lead them to the summit of Mount Olympus. The next day they started the ascent. At noon they reached the monastery of Agios Dionysios (820 m), went from there to Petrostrouga (1940 m) and stayed there overnight. On 30 July, they reached the Muses Plateau (about 2600 m) and climbed the peaks of Profitis Elias and Toumba. With the peaks of Mytikas and Stefani in mind, they decided to descend again and stayed in a log cabin (probably in the Paliokaliva) near today's mountain hut Spilios Agapitos (2040 m). On 31 July, they wanted to cancel their project and started their way back to Litochoro. During the descent, they changed their mind and stayed in Prionia (1100 m). On 1 August, they climbed back up to the lumberjack hut.
