"Perfect day," the 38-year-old sweetly captioned a lovely photograph with her 1-year-old son Tennessee.
The blond mother-son duo is sitting on a gorgeous beach and peering out at the clear blue ocean. The smiling Oscar winner, clad in a one-piece black swimsuit, is gazing at her little boy, who is adorably reaching up to his mama.
Even though they have their backs to the camera, it is clear that they are having a wonderful sun-filled day in the sand.
Witherspoon has been documenting the gorgeous views and posted a serene selfie during a beach stroll at sunset.
Witherspoon also showed off an adorable tropical outfit by Pret-a-Surf as she peered out at the ships sailing by.
As for her office during her "spring break" getaway? That would be a peaceful hammock with a pretty stunning view.
Before jetting to the Bahamas, Witherspoon recently celebrated her birthday with a good ol' fashioned trip to the bowling alley with her loved ones in Nashville.
"Having a ball at my birthday! #nashvegas #goodfriends #bowlersnotballers," she wittingly captioned a WhoSay snapshot on March 22.
