Haro Strait, Marine strait between Vancouver Island and San Juan Islands, United States and Canada.
Haro Strait is a marine passage between Vancouver Island and the San Juan Islands that links northward to the Strait of Georgia and southward to Juan de Fuca Strait. Water depths range from 180 to 275 meters, and the channel provides a direct route for large vessels to move between Pacific coastal regions.
Spanish explorers including Gonzalo López de Haro charted this area in 1788 as part of their survey of the northern Pacific coast. The waterway was named to honor these early European expeditions into the region.
Local Coast Salish peoples relied on these waters for fishing and trade for centuries before European contact. The strait remains a vital place where their maritime traditions continue to shape how people interact with the sea.
Visitors exploring these waters should be aware of strong tidal currents and water movements that occur at certain points along the passage. The best time to observe ship traffic and marine activity is during calmer weather with clear visibility.
Turn Point and Boundary Pass create distinctive whirlpools and strong current patterns where different water flows converge. Mariners today still navigate with caution through these areas, much as they have done for generations.
