The North Bay
Marin and Sonoma Counties

Marin County, just north of the Golden Gate Bridge, is known for its elegance and charm, and is one of the most naturally beautiful areas in California. Marin (pronounced "ma-RIN") is surrounded on three sides by water, and extends north from the Golden Gate Bridge, west to the Pacific coast and east to San Pablo Bay, with Mount Tamalpais standing majestically in the heart of the county.
Terrain: Marin features spectacular views of rugged cliffs, natural beaches, well-developed parks, rural farmlands and tiny hidden towns. It was here that the mountain bicycle was born. Though Marin's terrain can be fairly steep, once you get to the top, the views of the Pacific Ocean, Marin Headlands and San Francisco skyline are unforgettable.
Sonoma County, less than an hour's drive to the north, the landscape changes dramatically. To the north you will find towering redwoods forests, local wineries and the Russian River resort area. To the east is the Sonoma Valley and the "Valley of the Moon," made famous by Jack London. To the west you will find tranquil country roads and gently rolling farmlands, ending at the Pacific Ocean.
Climate: The climate of Sonoma County is as diverse as its terrain, from chilly and damp by the coast to hot and dry in the valley. That way you can always pick your favorite bicycling temperature any time of the year.
