Obama, wife Michelle and daughters Malia and Sasha spent several hours Saturday at Pyramid Rock, a secluded beach at Marine Corps Base Hawaii. It's the same base where the president starts his day with a morning workout.
The first family then hit the tennis courts at Kailua Racquet Club, a private club near the neighborhood where the Obamas are renting a luxurious oceanfront home.
Obama has made just a few, brief public appearances during his nearly two-week vacation. The Obamas are scheduled to leave Hawaii late Monday, arriving in Washington the following day.
