On your second day, take advantage of Fountain Valley's proximity to the beautiful Southern California beaches. Start your day by driving to Huntington Beach, also known as Surf City USA. Spend the morning soaking up the sun, swimming in the ocean, or trying your hand at surfing. Afterward, head to Newport Beach, where you can rent a bike and ride along the scenic boardwalk, explore the charming Balboa Island, or take a boat tour of the harbor. In the evening, enjoy a beachfront dinner at one of the many restaurants overlooking the Pacific Ocean.
