Updated March 10 In the summer, Sauvie Island is Portland s favorite rural retreat. Situated just 10 miles north of the city proper, it s an easy getaway for beachgoers particularly those looking to lounge in the buff and u-pickers hoping to score some fresh produce. Even at its most crowded, the vibe is still bucolic and sleepy. In the winter months, though, the island gets even sleepier. The beaches and hiking trails are pretty much empty, and there s no line of traffic searching for parking spots. Sure, there s a bit less to do even the most dedicated exhibitionist will think twice about stripping down and frolicking in the Columbia when it s 45 degrees and drizzly. But there s still winter bird watching: There are 250 bird species that can be seen on the island throughout the year, and in late winter, there s still a chance to catch sandhill cranes before they migrate north.
