Our visit to Walla Walla, Washington at the confluence of the Columbia and Snake Rivers did not disappoint. The region offers a bevy of activities. Everything from historical sites and museums to ice cream shops and wineries. Guests of National Geographic Sea Bird chose to learn about the region’s history of the Cayuse people at Whitman Mission, sampled wines from local vineyards and tasting rooms, and explored the lively downtown of Walla Walla with its many coffee shops, bookstores, and ice cream parlors.
