“Happy Days!” Thicke captioned the Instagram snap.
Thicke also shared a video of Julian excitedly taking in the views on a vacation helicopter ride, as well as a shot of the shoreline from the sky.
“It’s A Beautiful World!” the performer captioned the beautiful image featuring a rainbow effect.
Geary, 22, has also been actively sharing photos from the tropical trip, including a selfie showing Thicke giving her a kiss on the cheek captioned, “Mom & dad.”

“Robin and I are very excited to share with you all that we’re having a baby! The due date is March 1st, [Robin’s late father] Alan’s birthday!” Geary happily announced on Instagram Thursday, along with a photo of her sonogram, which was dated Aug. 14. TMZ reported that the baby is a girl.
On Friday, Thicke and Patton ended their custody battle over their son.
PEOPLE confirmed the pair has worked out a custody arrangement for Julian, seven months after an L.A. judge granted the actress’ request for a temporary restraining order against her ex-husband.
Thicke and Geary made their first public appearance together at the Cannes Film Festival in May 2015 after dating for over a year.
