Kendall, 28, followed suit by flaunting her chiseled abs in a black tank top and matching leggings as she strutted down the runway towards the awaiting jet.
Their 68-year-old famous momager brought up the rear, exuding sporty chic vibes with a black baseball cap and matching track jacket featuring her name printed on the back.
The family appeared in high spirits and engaged as they conversed while seated together during the yacht excursion.
After the boat docked, they each grabbed one of their totes and made their way to the airport.
Kendall also took to her Instagram on Saturday to share adorable snaps of the vacation, complete with a video clip of her and Kylie singing along to a Billie Eilish song.
She also shared pictures of a breathtaking beach they visited, nestled among rocky cliffs and pristine, crystal-clear waters.
The fabulous getaway comes after it was reported that the supermodel and Bad Bunny are officially back on again.
Kendall rekindled her romance with the Puerto Rican rapper, 30, nearly half a year after they initially called it quits back in December 2023.
Less than a half a year later, sources confirmed to People that they got back together recently because they ‘missed each other.’
After taking a short ‘break,’ Jenner was seen cozying up to her ex, born Benito Antonio Martínez Ocasio, earlier this month at a Met Gala afterparty, which seemingly sparked their romance again.
