Columbia River -- When to Go

Columbia River departures typically are scheduled from March through November. Summer is a particularly beautiful time to sail: Average monthly highs range from the mid-60s to high 80s in ports of call on June and July sailings, and late evening sunsets -- close to 9 p.m. in some locales -- allow plenty of hours to photograph the magnificent scenery along the river.

Fall foliage cruises in October showcase brilliant, leafy displays in hues of gold, yellow and orange.
