As a avid hiker, I like hiking at least 10 miles each time and prefer loops over point-to-point route. I also don't like to hike the same route week after week. Sometimes, I go through a few books without finding a single hike I like. There are too many short trails and too much scenery description in those books. That is the reasons why I write this book. You will find 60 great hikes in this book. These hikes scatter all over the whole bay area. Their lengths range from 10 miles to 30 plus miles. They have very little overlap. You can hike one route per week for 60 weeks without repetition For each hike, I provide overview map, length (distance), elevation, shade and parking information to help you plan your trip. There are also many screen shots for places where I think you might need help. Once you arrive there, you can follow the hike easily by reading my turn by turn directions. There is very little scenery description so you don't need search for hike directions.
