The 31-year-old has been out of action lately having contracted malaria while on international duty with Gabon last month.
He appeared to be in good spirits as he took a trip to Paradise Wildlife Park in Broxbourne, Hertfordshire with his family.
Pictures and video released by the park show Aubameyang feeding Amur tigers and Bactrian camels with his wife and children.
On Sunday he posted a picture on his Instagram Story of himself in the gym, with the caption: “Working hard tho”
