Our 18-night North American adventure encompasses some true west coast gems. Starting in sunny San Diego, we cruise north, stopping at the snorkeling hotspot of Santa Catalina, buzzy San Francisco, and forest-fringed Astoria. Canada offers up the cool cosmopolitan capital of British Columbia, Victoria, the arty harbor town of Nanaimo, and the bustling metropolis of Vancouver. Sailing through the Seymour Narrows to Alaska, we arrive at the fishing harbor of Ketchikan, followed by Alaska's cultured capital, Juneau, and Skagway, famous for its Gold Rush-era buildings. Witness the unforgettable spectacle of the Hubbard Glacier as we come to the formerly Russian-ruled city of Sitka and then Klawok, a significant Tlingit settlement. Then it's back to Victoria and our journey's end in Vancouver.
