Menlo Park → Vancouver

No romance here, and that's the point — you sanctioned the freeway to reach the start, so use it. I-580 to I-80 carries you over Altamont, past Sacramento, up and over Donner Summit into Reno, then out across the Great Basin. This is the trip's only real desert, and it's mostly sagebrush and big sky at 70 mph. Knock out a long first day to Winnemucca or push to Elko, then a short morning gets you to Twin Falls, where you turn off the slab and the trip actually begins.

ID-75 north out of the desert is the hard reset. You climb gradually through Hailey and into Ketchum/Sun Valley, then the road tips up to Galena Summit at 8,701 ft — pull off at the overlook just before the top, where the whole Sawtooth Valley and the saw-blade peaks open up below you. The descent into Stanley is one of the great mountain reveals in the West: a one-stoplight town (barely) cradled by serrated granite, with the Salmon River just starting its run. It's small, so book ahead, but waking up under those peaks is the reward for yesterday's slab.

Roll down the Salmon River on ID-75, then cut east on US-20/26 across the upper Snake River plain toward Idaho Falls (the one mildly flat, faster stretch of the day — refuel and push on). Beyond Swan Valley the road rises into the Teton foothills, and the finale is the steep, switchbacked climb over Teton Pass (WY-22, 8,431 ft) — a short, sharp, 10% grade with the Tetons exploding into view as you crest. Drop into Jackson for the night.

The headline route runs straight up through Grand Teton along the range, into Yellowstone, then out the East Entrance and down the North Fork of the Shoshone — the Wapiti Valley, which Teddy Roosevelt called the most scenic 50 miles in America — into Cody. It's the iconic line and worth it, but be honest with yourself about July park traffic and the 45-mph reality of the road.

This is the day you planned the trip around, and it's worth riding slow. Head north from Cody and turn onto WY-296, the Chief Joseph Scenic Byway — a swooping, lightly-trafficked climb to Dead Indian Pass (8,071 ft), where you can see the whole switchbacked descent laid out ahead and the Beartooth plateau beyond. At the junction with US-212 you have a choice: dart west a few miles to Cooke City and the wildlife-thick Lamar Valley at Yellowstone's quiet northeast corner, or turn east and climb the main event.

The Beartooth Highway tops out at 10,947 ft — the high point of your entire trip — on a staircase of switchbacks through alpine tundra, snowbanks (in July there can still be 10-ft walls of it), and turquoise glacial lakes, before the long sweeping descent into Red Lodge. Two to three hours of pure road; give it the whole afternoon.

A connective day — but a pretty one if you stay off I-90 where you can. From Red Lodge work west to Bozeman, then drop the throttle into the Madison Valley on US-287 through Ennis and the gold-rush ghost-ish town of Virginia City. Past Butte, the Pintler Scenic Byway (MT-1) loops you around Georgetown Lake and through Anaconda, spilling into the Bitterroot and on to Missoula — your base for tomorrow's Lolo run. Split it however your legs feel: a night in Bozeman or Butte keeps the days short.

Lolo points west — the wrong way for Calgary — so rather than wrench the whole route around it, ride it as a dedicated day from a Missoula base and come back grinning. And it earns the detour: the pass itself (5,233 ft, right on the Idaho line) is gentle, but the magic is the far side, where US-12 chases the Lochsa River down a tight, tree-walled canyon for some 66 miles of uninterrupted curves with almost no traffic and no towns. Run it out to Lowell, grab lunch, and ride the whole thing back — it's a completely different road in the other direction.

US-93 north skirts the long blue edge of Flathead Lake — the biggest freshwater lake in the West — through cherry-stand country to Whitefish/Columbia Falls. Then comes Going-to-the-Sun Road, the alpine highway carved into the Garden Wall, climbing to Logan Pass (6,646 ft) past waterfalls and hanging valleys before descending the east side to St. Mary. On two wheels, in the open air, it's one of the best roads on the continent. Break the run with a night near West Glacier so you can hit the road early.

From St. Mary, US-89 runs up to the Carway/Piegan border crossing into Alberta. Now resist the urge to slab straight into Calgary on the prairie — instead pick up Highway 22, the Cowboy Trail, rolling along the foothills with the Rockies as a constant left-hand wall, to Longview. There you turn west and climb Highway 40 over Highwood Pass — at 7,239 ft, the highest paved road in Canada — through Kananaskis Country, before the final descent into Calgary. A fitting high note before the coast run: you've climbed from desert heat to the spine of the Canadian Rockies. Rest, refuel, and point the bike west.

Leave Calgary westbound and the prairie buckles into mountains almost at once. Hwy 1 carries you through Canmore and into Banff, then up to Lake Louise and over Kicking Horse Pass (5,338 ft) at the continental divide into British Columbia and Yoho National Park. Past Golden the road threads Rogers Pass through Glacier National Park — high, avalanche-sculpted, and ringed by ice — then drops to Revelstoke, a good second night. This stretch is the green, high crown of the whole trip: glaciers, cedar rainforest, and big mountain rivers, not a cactus in sight.

From Revelstoke the country gradually dries as you descend the Thompson valley toward Kamloops — your one taste of BC's semi-desert interior. From there two ways down to the coast: the Coquihalla (Hwy 5) climbs higher and stays in the timber over Coquihalla Summit (4,081 ft) before dropping to Hope, or the older Fraser Canyon (Hwy 1) trades altitude for drama, hugging the gorge past Hell's Gate. Either lands you at Hope, where the last hour runs the broad Fraser Valley into Vancouver and saltwater. Wheel to the sea — you've earned it.
