Washington Bikes is an advocacy group that promotes bicycling in across Washington. Their web site deals with a variety of topics of interest bicyclists and answers some of the most frequently asked questions.
Especially valuable information is found in the section of the web site under Resources. This section has a comprehensive list of “Trails for Beginners” which lists almost all trails in Washington and a list of “Bike Maps” for each county with the date the map was updated (except the map for Pierce County which was updated last year). Other valuable information under Resources includes “Bike Laws” and an article for business owners who want to attract bicyclists to their businesses. For bike commuters, here is a list of locations of bike lockers if you are commuting and linking up with a bus, ferry or train.
