Jennifer Garner joined Ben Affleck in Hawaii so the entire family could spend Easter together, a source tells ET.

The Love, Simon star visited her ex-husband on the island, along with their three children, Samuel, 6, Seraphina, 9, and Violet, 12, while he filmed Triple Frontier, according to the source.

"They had a great weekend with the kids," says the source, adding that Affleck has been "back and forth to L.A. a number of times during training" while shooting the movie. 

"There is a lot of love and respect there and he was overjoyed to have them all there for the long weekend," the source says of Garner and the kids jetting off to Hawaii. "He enjoyed showing them around."

On Saturday, Garner posted an Instagram pic during what looked like a picturesque rain forest hike with celebrity fitness trainer, Simone De La Rue.

"A perfect morning hike with my buddy @bodybysimone," the 45-year-old actress captioned the selfie. "#Aloha and #mahalo!"

As for Affleck, he has been seen shirtless on several occasions while shooting Triple Frontier -- which led to many questions about the 45-year-old actor's unique new back tattoo.

Despite filing for divorce last April following their separation in 2015 after 10 years of marriage, Affleckand Garner have focused considerable efforts on co-parenting. Last summer, the family of five all spent Fourth of July together in Brentwood, California, attending a holiday parade. They also had Thanksgiving together in Brentwood with Affleck's mother.
