From their website: Opal beach was created in 1995 when Hurricane Opal flattened sand dunes to create a smooth, sandy stretch of beach. Today, you can relax and enjoy a day of picnicking along the white sands. The covered picnic area faces the azure waters of the Gulf of Mexico, with limitless opportunities for beach activities. The area is part of the Gulf Islands National Seashore on Santa Rosa Island. Santa Rosa is a 40-mile barrier island once explored by Spanish Conquistadors in the early 16th century.
