The 26-year-old star spent time with Italian entrepreneur Gianluca Vacchi, Vacchi's girlfriend Giorgia Gabriele, actress Michelle Rodriguez and dancer Youssef Giga. Vacchi documented the group's exploits on Instagram, which included lounging on docks and dancing on tables.
In the first video, Efron sits shirtless with Vacchi, Gabriele and an upside-down Rodriguez. The businessman writes in the caption, "Welcome to my friends Michelle @mrodofficial and Zac @zacefron at l'Eremita....enjoy #GVlifestyle."
In a later video, the former High School Musical star shows off his dance moves to "Wiggle." The actor, Vacchi and Giga dance on the table to the Jason Derulo song.
Efron will next appear in an adaptation of John Grisham's The Associate in 2015. He will also star in an episode of Running Wild with Bear Grylls, that will see him go on a wilderness adventure with the British survivalist host.
