Affleck, who is currently filming Justice League in London, arrived in the French capital on Thursday with Garner and their kids: Violet, 10, Seraphina, 7, and Samuel, 4. That same day, the family indulged in some sweet treats at the Amorino ice cream parlor.
“They are so excited for this opportunity for the kids,” a family friend tells PEOPLE. “He is shooting over there and they will likely come back and forth. He similarly brought the kids to the set during Miracles From Heaven. This is normal for them.”
Affleck was not spotted with the rest of his family on Friday as Garner took the children to the Roue de Paris and held Samuel in her arms while waiting in line for the renowned Ferris wheel. From there, she and the kids went on a tour of the Place de L’Opéra, where Garner took photos on her cellphone as a hired guide talked through the history of the famed opera house.
The Miracles from Heaven star and and the kids continued to Montmartre, where the doting mother took selfies with her two daughters and ended up throwing a tired Seraphina across her back as they continued up the last flight of stairs leading to Sacré-C ur Basilica.
Later, Garner and the kids visited the Jardin du Luxembourg, a sumptuous garden dating back to the 17th century, where the kids were spotted having fun while operating sailboats around a fountain.
Before arriving in Paris on Thursday, the family spent time in London, with a Twitter user posting that the family was spotted on the Harry Potter tour at Warner Bros. Studios Leavesden.
They are enjoying showing the kids London,” a source close to the family told PEOPLE.
Since announcing their split in June, both Affleck, 43, and Garner, 44, have stressed that they are focused on their children, and have not yet filed for divorce.
“We’re doing our very best and we’re putting our kids first and that’s how we’re focusing on our day-to-day lives,” Affleck said on CBS This Morning in March. “We don’t know what the future’s going to hold, but each step that we take is one where we prioritize our children and everything else comes second.”
