On the South Shore of Oahu, Sandy Beach is a lovely sunrise spot with a powerful shore break that made for good body surfing. Getting clobbered by waves is always an effective way to wake up.
Post-swim, I'd drink a cold brew provided by the rustic road-side coffee cart and watch photographers with massive lenses (in the water!) trying to get the perfect shot of a barrel.
Sandy Beach is a great way to start the day.
