Between spring and fall of 2019 I plan to cycle around the US. The trip from Seattle to the East Coast and back will pass through 36 states and five provinces, as well as 20 US national parks. The route is as follows:
Month 1: Ride down the Pacific Coast and visit the Dutch town of Solvang. Seattle » Redwood National Park » San Francisco » Solvang » Los Angeles
Month 2: Cross the Mojave Desert and experience America's monuments. Los Angeles » Joshua Tree National Park » Grand Canyon National Park » Zion National Park » Bryce Canyon National Park » Capitol Reef National Park » Moab
Month 3: Continue experiencing America's monuments. Then waste no time crossing the plains of Nebraska / Kansas. Moab (Arches National Park) » Black Canyon National Park » Rocky Mountain National Park » Fort Collins » St. Louis
Month 4: Visit friends in the Midwest. St. Louis (Gateway Arch "National Park") » Iowa City » Chicago » Indiana Dunes National Park » Ann Arbor » Cleveland » Cuyahoga Valley National Park » Washington, DC
Month 5: Take a break in Washington, DC, then slowly ride up the Atlantic Coast. After taking another break in Boston, continue to Maine, then cross into Canada. Washington, DC » New York » Boston » Bar Harbor (Acadia National Park) » Quebec
Month 6: Ride up the St. Lawrence River and cross Upper Michigan. Quebec » Montreal » Ottawa » Toronto » Bruce Peninsula National Park » Duluth
Month 7: Cross the Northern plains and Rockies. Duluth » Badlands National Park » Rapid City (Wind Cave National Park, Mt. Rushmore National Memorial) » Grand Teton National Park » Yellowstone National Park » Glacier National Park
Month 8: Ride up to Banff and Jasper in Canada, then return to Seattle. Glacier National Park » Banff National Park » Jasper National Park » North Cascades National Park » Seattle
Of course, I don't really know right now how long this will take me, or whether I can finsh this at all. Only time will tell.
This is an abbreviated Pacific Coast tour, starting from Seattle (instead of Vancouver / Victoria) and ending in Los Angeles (instead of Tijuana).
I took a few days' break in San Jose, then kept going.
