MTV – The Hills (season 5 episode 5)
Wow, they filmed right at the Ocean Villas. Lauren Conrad, Audrina Patridge, and Lo Bosworth stayed at the Turtle Bay Ocean Villas. The cast laid out at Keiki Beach (kids beach at Turtle Bay). They also had a private bon fire at Kawela Bay (the private beach area owned by Turtle Bay). Brody Jenner was filmed surfing at Sunset Beach, he was actually pretty good (if it was actually him).
