It’s a red, white and blue vacation for Kylie Jenner‘s 19th birthday in Turks and Caicos: red bikinis, white sand beaches and clear blue waters.

The youngest Jenner, who is celebrating her August 10 birthday soaking up the sunshine with her 20-year-old sister Kendall Jenner, shared snaps from her island life getaway on Wednesday.

“19 & 20,” she captioned the first photo of the pair taking in the surf and sand while laying on the beach.

Kylie followed her first snap with a second photo of the duo – who both sported red bikinis – sitting side-by-side on their boat.

Earlier Wednesday, the birthday girl posted photos with her friends both sitting on the beach and leaning on the bow of the boat with the captions, “blessed” and “time of my life.”

Following their day on the water, the group watched fireworks – a gift from Kendall – and lit sparklers after the sun went down. “Happy birthday to me, I have the best friends,” Kylie captioned a Snapchat video of the fireworks.

“Thanks for all the birthday wishes,” she later captioned a picture of herself from behind. “Best Birthday Yet.”

Happy birthday, Kylie!
