Goose Island State Park is bounded by Aransas and St. Charles bays just across St. Charles Bay from the Aransas National Wildlife Refuge and twelve miles northeast of Rockport in Aransas County. The 307-acre park consists of Goose Island and a section of the mainland. The area was purchased by the state between 1931 and 1935 for a wintering grounds for the endangered whooping crane. It is also home to numerous migratory and local birds. Boating, fishing, swimming, and camping are permitted. Among the park's features is the "Big Tree," estimated to be 2,000 years old and certified as the largest live oak in Texas.
