Haro Straight is a channel of water that connects the Straight of Juan de Fuca and the Straight of Georgia. The Canadian-American border runs down the center of the straight. It is a major shipping lane for cargo ships, cruise liners, ferries, ecotourism boats and private vessels. Haro Straight runs along the western shores of San Juan Island, which is where the majority of whale watching trips are spent, watching resident orca feed, rest and socialize.
