🏆 San Juan Islands — Protected bay on San Juan Island — in the heart of Washington’s stunning San Juan Islands archipelago, prime orca whale watching territory
Griffin Bay is a protected anchorage on the southern end of San Juan Island — in the heart of the San Juan Islands archipelago, one of the most beautiful places in the Pacific Northwest. The San Juan Islands (172 named islands!) sit in the rain shadow of the Olympic Mountains, creating an unusually sunny and dry microclimate. Griffin Bay offers some of the best orca whale watching in the world — the Southern Resident Killer Whales (currently ~75 individuals) pass through these waters regularly. The bay was named by the Wilkes Expedition (1841) and played a role in the “Pig War” boundary dispute between the US and Britain.

Frequently Asked Questions
What was the Pig War?
In 1859, an American settler on San Juan Island shot a British-owned pig that was eating his potatoes — nearly triggering a war between the US and Britain over the disputed Oregon Territory boundary. Both nations sent troops. For 12 years, American and British soldiers occupied opposite ends of San Juan Island in a tense but peaceful standoff. Kaiser Wilhelm I of Germany arbitrated in 1872, awarding the islands to the US.

Wildlife & Nature
Griffin Bay — a marine camping area on the south coast of San Juan Island — provides mooring buoys and primitive camping for boaters exploring the San Juan Islands. The bay’s kelp beds support a rich marine food web — harbor seals, river otters, and Dungeness crab inhabit the waters. Bald eagles patrol from the shoreline trees. The bay faces south toward the Strait of Juan de Fuca — orca whales (Bigg’s transient pods) travel through these waters year-round. The anchorage is protected from prevailing northwest winds.
