When you think of Humboldt County, you likely think of something other than world-class cycling (something, shall we say, greener). With clean Pacific Northwest air, endless redwoods and brutal hills, the North Coast roads will thrill even the most veteran cyclist. Don't miss what the locals call "The Wall"—a one mile climb that boasts an impressive 18 to 22 percent grade. After you've caught your breath, head to one of the local award-winning craft breweries to recover.
