San Francisco - Biking

For an urban area of its size, San Francisco has a surprising amount of open space for bikers. Golden Gate Park has miles of trails through beautifully landscaped terrain, its north and south sections linked by the "The Bridge", which is also a good place to enjoy a sight-seeing spin. South of the city, a series of open space preserves in the Santa Cruz mountains provide trails for bikers within a half hour drive of the center (call 650-691-1200 for more information).
