Brooke Shields makes a splash in black swimsuit during action-packed Croatia trip

Brooke Shields found her "highlight of the summer" on an adventure-filled getaway to Croatia.

The 61-year-old actress and model shared highlights from a trip with friends, including Chelsea Handler, that took her from the streets of Croatia to waterfalls and the open water.

Shields kicked off the Instagram carousel with a striking photo of herself sitting beside a rushing waterfall in a black strapless one-piece swimsuit.

Her dark hair was slicked back as she finished the strapless black swimsuit look with a gold chain necklace and bracelets.

"Highlight of the summer: the most amazing trip to Croatia with the best people 🇭🇷😍🏝️," Shields captioned the Instagram post.

Shields stretched out on a wooden swim platform attached to a boat while wearing the same black one-piece.

Handler, 51, sat nearby in a turquoise swimsuit, while another woman smiled from the water in a red bikini top and patterned bottoms.

Shields and Handler have been friends for years, with the two previously appearing on each other's podcasts and speaking candidly about their lives and relationships.

Away from the water, Shields traded her swimsuit for a bright yellow dress while exploring Croatia with Handler.

The "Pretty Baby" star paired the loose-fitting dress with a wide-brimmed straw hat, layered necklaces and a brown belt.

Handler stood beside her in a white button-down shirt, patterned skirt, navy baseball cap and dark sunglasses as the two smiled for the camera on a busy street.
