This is the Adventure Cycling map of the Lewis and Clark bicycle trail, from Seaside, Oregon to Clarkston, Washington . I have to cycle about 100 miles in the “wrong” direction to get the iconic rear wheel in the Pacific Ocean photo and then begin my eastward trek. The black line is the route. Where there are two lines, the choice is optional. These are great maps with detailed sections for each segment, riding conditions, elevation profiles, historical temperature charts, and more.
