Easy to reach by ferry from Port Aransas, this former ranch is now a prime beach destination. Because San José Island is privately owned, the island’s only publicly accessible land is its 21-mile stretch of unspoiled sand situated below the vegetation line. But visitors will find plenty to do on the beach. The island’s more than 600 kinds of fish and roughly 300 bird species make it a terrific place to go fishing and birding. Other popular pastimes here include shelling and surfing.
