Fifth in size in the San Juan Islands, Cypress is also one of the least populated. With the majority of the island protected as a state Natural Resources Conservation Area, it is also one of the wildest. A network of hiker-only trails interlaces this forested island of mountain lakes, grassy balds, and isolated coves. Surrounded by rocky headlands and the protective buffer of the Cypress Island Aquatic Reserve the island is famous for its wildlife and rare plant communities. With access limited to boats and no ferry service available, getting to the island is an adventure in itself and another of its popular appeals. The public is welcomed for day visits year-round but there are seasonal closures for the camp sites on the island as well as the springtime closure of the Eagle Cliff Trail to protect nesting raptors. For what is truly a walk on the wild side, a visit to Cypress Island offers the adventurous one of the more unique and natural of the island experiences.
