Otto is not just a classic camper van that can be rented for a vacation – he is also a magic bus. In this summer holiday adventure, his vacation family – twins Klara and Luzie with mom Yurika and dad Christian – takes him to the mountains: hiking over alpine meadows and to the most beautiful peaks, stopping for snacks with traditional platters, Kaiserschmarrn, and more, exploring fairy-tale castles, enchanted forests, and experiencing the Alpine descent with alpine horns, flower crowns, and chocolate. At the end of the audiobook, it’s Ciao, servus, pfiat di, baba, and ade – until the next Otto adventure.
