St. Andrews State Park in Panama City Beach sits on the Emerald Coast at the pass between the Gulf of Mexico and St. Andrews Bay. White sand beaches, a lagoon and rock jetties give it a wide range of habitats and activities. Swimming, snorkeling near the jetties and fishing are popular, and a shuttle service runs to Shell Island, a pristine barrier island reachable only by boat. Nature trails, campsites and picnic areas add to the appeal. Entry is $8 per vehicle. It is a top choice for families visiting Panama City Beach who want a more natural setting than the busy resort areas.
