The actress, 26, first took a snap of her legs and perfectly polished toes as she reclined in a comfy sun lounger in front of a beautifully blue swimming pool.
In the distance, Lea - who plays Rachel Berry in Glee - also got a glimpse of the sea and the straw roof of a tiki hut.
Alongside the picture, Lea commented: "And I don't plan on moving all day..."
But it seems the hot weather and the temptation of the pool got the better of her, as Lea then uploaded a photo of herself lazing in the shallow end of the water.
Sitting in a royal blue bikini top, white bottoms and a large sunhat, Lea joked: "I moved...lol."
Sadly, while we're sure Lea wished she could've stayed at the luxurious beach resort longer, all good things come to an end.
Wearing a white and navy striped bikini and with her long brunette hair still damp from the water, she shared a final snap of herself standing in a star shape while looking out to sea before jetting home to Los Angeles.
"Last look at paradise!" she wrote next to her picture. We're not jealous...much!
