Ashley Greene and Vanessa Hudgens showed off their bikini bodies — and athleticism — at Oakley's Learn to Ride event in Bali, Indonesia, today. The ladies both hopped on surfboards to catch a few waves at the event, which serves to promote the sport of surfing. Ashley and Vanessa were sharing the perfect conditions with pro surfers since the event coincided with Oakley's Pro Bali surf competition as well. Although Ashley was able to successfully ride the waves, she did not escape the day without injury. She shared a picture of her leg, which was covered in scrapes, on her Twitter account, writing, "War wound from surfing today with Oakley. The reef ate me up." While Ashley and Vanessa were enthusiastic to try their hand at the water sport, the girls did find time to relax and soak in the Indonesian rays on a boat during the day as well.
