Swallows always return to the Mission San Juan Capistrano. Monarch butterflies have the sanctuary trees of Pacific Grove. And grasshoppers? Well, they come to the wooded hamlet of Occidental, California. In case you didn’t know, “grasshoppers” have been flocking to this sacred spot for the past 20 years—not to take rest on their yearly migration, but to test themselves on two wheels. Yup, we’re talking about cyclists and the local Grasshopper Adventure Series, a collection of six unique cycling events that incorporate a wide range of the best (and worst) paved and dirt roads that Sonoma County has to offer. Over the years, riders from as far away as Canada and Colorado have made annual pilgrimages to Occidental to test their cycling skills.
