Our west coast map, covering from Vancouver down to Tijuana has proven to be one of the most popular maps published by ITMB. This edition closely resembles previous ones, in that it focuses on the road network from north to south, covering all of Washington State, Oregon, and California on one double-sided sheet, showing all passenger-service railway lines as well. By the shape of the area covered, the western portion of Nevada is also shown as well. Space limitations did not enable us to include insets, so travellers should be advised to obtain ITMB city maps of Seattle, Portland, San Francisco, Los Angeles, and San Diego to supplement this map with more detailed coverage. This map also includes Yosemite National Park, for which ITMB also provides a separate detailed map. Hundreds of wilderness campgrounds are also included.
