Guemes Island has a rural character with limited facilities. Some of the island’s beaches are public but most beaches access is private. There are also two parks: one in the middle of the island known as Schoolhouse Park, and another, Young's Park, located on North Beach near The Guemes Island Resort. The community located on Guemes Island is generally referred to as "Guemes".
History
Guemes Island is within the historical territory of the Samish Nation. Around 1873, the Samish, displaced from their original village by U.S. government policy that made land available to newcomers, established a new village on Guemes near Potlatch Beach. Because they occupied the only natural spring on the island, the Samish were forced off the island by their neighbors in 1912. Guemes Island was named by the Spanish explorer José María Narváez as Isla de Güemes during the 1791 expedition of Francisco de Eliza, in honor of the Viceroy of Mexico, Juan Vicente de Güemes Padilla Horcasitas y Aguayo, 2nd Count of Revillagigedo. In 1841 Charles Wilkes of the United States Exploring Expedition gave the name "Lawrence Island" to Guemes Island, to honor the American naval officer James Lawrence. He also gave the name "Hornet Harbor" to Guemes Channel, for the USS Hornet, which Lawrence commanded during the War of 1812. To the waterway north of the island, part of Bellingham Bay, Wilkes gave the name "Penguin Harbor", for the British vessel Penguin, captured by Lawrence. These names disappeared after 1847, when the British Captain Henry Kellett reorganized the British Admiralty charts, in the process removing the "pro-American" names given by Wilkes and affirming pro-British names and Spanish names. Guemes Island was also commonly known locally as Dog Island in the early 20th century, from the large number of Salish Wool Dogs living wild on the island.
