Look for sea ducks, gulls, and terns as you walk across the causeway to Clark Island. This 124-acre island preserve in St. George has diverse habitats that include spruce and hardwood forests, orchards, hay fields, and granite quarries with a multitude of wildlife. This is an easy 1.8-mile round trip hike on the island’s centered gravel roadway and quarry loop trail. Meet at the Craignair Inn parking lot.
