The San Francisco Bay Area contains an enormous and diverse selection of trails, paths, and trail systems. It appeals to outdoor enthusiasts of all skill levels, ages, and walks of life.

The northern areas of Marin, San Rafael, and Santa Rosa are home the birth of mountain biking. In the 1970s and 1980s Joe Breeze, Gary Fisher, and the rest of the gang converted old klunkers into what would eventually evolve into modern day mountain bikes. The trails in the area evolved with them.

The South Bay Area is home to areas like Palo Alto, Gilroy, San Jose, Santa Cruz, and points along the peninsula. There are hundreds of miles of trails to enjoy for all kinds of users.

The East Bay is home to parks and systems that challenge and entertain. Joaquin Miller, Mount Diablo, Chabot, Pleasanton Ridge, and many others are amazing places to breathe clean air and enjoy the springtime lush vegetation and dry hills in the fall.

Modern mountain biking, hiking, horseback riding, moto, and many other outdoor activities are enhanced by the quality and variety of trails that are within easy reach of most metropolitan areas.
