Paddling along: Julia and her pal had a good laugh as they went paddle-boarding together.
Most people go on holiday to kick back, relax and generally forget their everyday woes.
But Julia Roberts clearly prefers the active way of life, and chose to spend a day paddle-boarding with a pal, rather than chilling out on a sun-drenched beach.
The Eat Pray Love actress seemed thrilled with her choice of activity, and was smiling and laughing as she moved through the water in Kauai, Hawaii.
Casual: Julia wore appropriate attire for her activity, opting for board shorts and a long-sleeved T-shirt to shelter her from the sun's rays
Dressed casually in board shorts and a long-sleeved T-shirt, the 44-year-old star didn't look out of breath at all she carefully navigated her way down the river.
Being such a fan of the active lifestyle, it's no wonder Julia has got a body most women half her age would envy.
Over the weekend, the Pretty Woman star was spotted soaking up the sun on the beach.
