The former Hills star, 27, was pictured walking along the empty sand yesterday (24 July) while holding her sunhat above her head.
Lauren had kicked off her shoes and was wearing a simple cotton dress as she gazed out at the vast blue ocean and into the distance.
Sharing the photograph on Instagram, Lauren joked: "If anyone needs me, I'll be making sandcastles..."
Lauren is thought to be visiting Nantucket, a small island located 30 miles south of Cape Cod in the US.
While there, she has also shared a candid close-up photograph showing just her right eye, perfectly applied black eyeliner and her straw hat. Stunning!
