This route generally follows WA-525 across Whidbey Island, the North Cascades Highway (WA-20) through North Cascades National Park, US-97 along the Columbia River Gorge, and the Stevens Pass Highway (US-2) back across the Cascade Mountains.
The long and narrow Whidbey Island, the largest island along the West Coast of the US, shows you a different side of the Washington coast, without the development of the Seattle area but still easily accessible from it. The historical chokepoint for maritime access into Puget Sound, the island retains much of its history, small-town charm, and natural seascapes.
The Skagit River is the largest watershed emptying into Puget Sound. In spite of three dams, the Skagit supports all five species of Pacific salmon and two anadromous (or sea-going) trout.
Abundant rain and mild winters provide the perfect environment for trees in the Pacific Northwest to grow large. The old giants are long gone in most of the Northwest, but in the wilds of the North Cascades you can still find groves of old-growth that have never been cut.
The North Cascade Mountains are still rising, shifting and forming. Unlike the rest of the Cascade Range, these mountains are a collage of terranes, distinct assemblages of rock, likely formed thousands of miles south as prehistoric island arcs (think Japan and Indonesia) in the Pacific Ocean. Colliding with the North American Continent, the drifting rock masses were thrust upwards and faulted laterally into a jumbled array of mountains. The north-south trending faults are still evident today. The North Cascades boast over 300 glaciers and countless snowfields, making them the most heavily-glaciated area in the United States outside of Alaska (more than Glacier National Park!).
The mighty Columbia River is the largest river system in the western US. The unique setting of the river is due to floods of molten basalt from what is now the Yellowstone Hot Spot, followed by repeated mass floods at the end of the last ice age, when the collapse of huge ice dams near Missoula, Montana unleashed walls of water over 1000 feet high, carving distinctive canyons locally known as coulees. Today, the soils in the canyons and valleys where the plateau meets the foothills are the most productive anywhere, and are the source of Washington's most famous agricultural exports.

Driving is the only way to experience this loop. Public transit is sparse and does not stop at natural points of interest. All roads on this route are paved and well-maintained. You could cycle across much of the route if sufficiently motivated, but this is rarely done over Stevens Pass, as the highway is steep, narrow, and high-traffic. Consider the Palouse to Cascades Trail across Snoqualmie Pass instead.
The North Cascades Highway closes in the winter, from approximately November to May. While the areas on either side of the closure still offer plenty to see in the winter, you will not be able to complete the loop. Stevens Pass Highway remains open, but sometimes closes during storms or for avalanche control. Check the Washington State Department of Transportation for winter travel information.
The weather is best in the summer. Puget Sound and areas west of the Cascades experience frequent cloud cover and drizzle outside of summer, which could put a damper on scenic vistas and idyllic hikes. The eastern slope the Cascades gets hot in the summer, but this route mostly stays at high enough elevation to avoid extreme heat.
If you only intend to cross the Cascades one-way and must choose only one of the mountain highways, the North Cascades Highway is regarded as more scenic and wild, but is also slower and further away from other regional destinations.
住宿
[]While the 440-mile loop can be driven within a day, that would not leave any time for stops. Two days will allow enough time to enjoy scenery and briefly walk around each of the stops. Three or more days will allow you to go on an extended hike or experience the other outdoor recreation opportunities.
The best towns to stop in for a night are La Conner, Winthrop and Leavenworth, as they have a lot of charm and places to eat. Anacortes, Burlington, Chelan, and Wenatchee are also larger towns with many lodging options available. You should also consider a more rustic motel or cabin in the foothills of the two mountain highways.
There is ample camping along the mountain highways. These need to be reserved in advance in North Cascades National Park, or on busy summer weekends.
费用和许可证
[]Washington State Ferries charge a toll for transit. Pay at the booth as you drive up. You can avoid the ferry (and Whidbey Island) by shortcutting through Interstate 5 between Everett and Burlington.
Many of the stops along the route are in Washington State Parks. State Parks require a pass to access. The Discover Pass is $10 a day, or $30 a year. You can pick up a pass at the entrance to most larger state parks.
North Cascades National Park is free to enter and explore. However, most of the other trailheads in the Cascades are regulated by the U.S. Forest Service. You're free to get out and look for a few minutes, but if you plan to hike, you need a federal parking pass on each vehicle. You can pick up a pass at any ranger station or park visitor center.
- United States Interagency Annual Pass ($80 online, valid for unlimited use at all United States National Parks, National Forests, and National Monuments for one year)
- Northwest Forest Pass ($30 online, valid for unlimited use at all United States National Forests in the states of Washington and Oregon for one year)
- National Forest Recreation Day Pass ($5 online and valid on one self-selected day only).

[]
This itinerary describes the route as starting from 埃弗里特, then going clockwise. Feel free to start from anywhere along the route, and go in any direction.
If coming from Seattle or other points south, you can also instead start at 穆基尔特, by taking Interstate 5 north to WA-525 at Lynnwood.
The loop has been divided into four main sections, each side of the roughly-rectangular route.
惠德比岛
[]From Everett, take 
WA-526 West to the Mukilteo Ferry Terminal. Catch the next ferry to Clinton (a ferry runs about once an hour).
Washington State Ferries is the largest ferry system in the country. Most routes crisscross Puget Sound, shortcutting a long drive south through the Tacoma Narrows Bridge, and providing vital mainland access to the larger islands in the sound, as the Mukilteo-Clinton Ferry does. If you need to wait for the next sailing, stroll the Mukilteo waterfront. Return to your car as soon as you see the ferry docking up - once you see cars unload, you only have a few minutes until it's your turn to board!
Once underway, explore the boat, including the outside upper deck. If you're lucky, you might see whales or porpoises as you cross Possession Sound.
From Clinton Ferry Terminal, continue onto 
WA-525 North.
Arrive in 克林顿, at the foot of Whidbey Island. Long and narrow, it is the largest island along the US West Coast. The main road running along the spine of the island passes through pastoral countryside and cute little towns such as Langley and Coupeville.
探索 埃比登陆国家历史保护区 to see the Admiralty Head Lighthouse and walk the beach. Admiralty Inlet, to the west, is the chokepoint for shipping into Puget Sound. This made the inlet critical to defend in pre-modern times, leading to the construction of a series of artillery forts. If you're at all interested in military history, visit 凯西堡州立公园 
and 埃比堡州立公园 .
At Keystone, WA-525 becomes 
WA-20.
At the north end of the island is the beautiful 欺骗山口州立公园, with beaches, freshwater lakes and trails. Stop at the parking lot just before the Deception Pass Bridge, and stroll across the bridge's walkway. This bridge was built by the Civilian Conservation Corps during the Great Depression. Look down into the water; if the tide is flowing, you may see the standing waves, large whirlpools, and roiling eddies that make this passage treacherous for sailors.
Drive across the bridge, onto to Fidalgo Island. Detour a few minutes to 阿纳科特斯, a working harbor town and a major ferry terminal. If you have the time, an orca whale watching tour makes for a great day, and catching the ferry to the San Juan Islands makes for a wonderful overnight trip.
北喀斯喀特公路
[]From Anacortes, take WA-20 East.
Cross the Swinomish Channel to the mainland, and enter the Skagit Valley. This fertile valley is famous for its tulips and claims to grow more of these flowers than Holland. If visiting during the spring, give yourself extra time to explore the Tulip Festival and the vibrant colors in the surrounding farmlands. The colorful town of 拉孔内, a couple minutes off the highway, has several blocks of waterfront dining, galleries, and boutique stores.
WA-20 crosses over Interstate 5 at Burlington, where it becomes the North Cascades Highway. After Sedro-Woolley the Skagit Valley narrows, the fields give way to dense forest, and the imposing Cascade Mountains come into view. Concrete and Marblemount are the last towns of any size until after the mountains, so make a pitstop if you're hungry or running low on fuel.

Arrive at the entrance to North Cascades National Park at Newhalem. This underrated park protects the most remote and rugged terrain of the entire Cascade Range. A visit to the 北喀斯喀特游客中心 will tip you off to the dramatic scenery that lies ahead. Let a ranger help you choose from the overwhelming number of trails, for whatever your time and energy allows. From here, drive along a number of scenic lookouts, including 峡谷溪瀑布, the emerald-green 迪亚布罗湖, and crystalline 罗斯湖. The highway climbs up to 雨季山口, a wonderful viewpoint and a popular trailhead for the Pacific Crest Trail. The road ascends even higher up to 华盛顿山口, the highest point on this loop at 5477 feet. Leaving the park, the highway finds the Methow River, and descends into the Methow Valley. 马扎马, just off the highway, is a popular rock climbing destination.
Stretch your legs in 温斯洛普, a cute town that still retains the flavor of the Old West frontier. Winthrop is a premier spot for cross country skiing, with one of the world's largest network of ski trails. Continue down the valley, out of the mountains and towards the Columbia River.
2 miles southeast of Twisp, continue straight onto 
WA-153 South.
哥伦比亚河
[]At Pateros, turn right onto 
US-97 South.
在 帕特罗斯, the Methow River flows into the Columbia River. You've reached the edge of the Columbia River Plateau, where an ancient flood of molten basalt covered much of Eastern Washington, and then was carved up by the most grand river of the Pacific Northwest. Dams along this river, including the Wells Dam along this route, provide most of the irrigation and electricity for Eastern Washington.
13 miles south of Pateros, turn right onto US 97-A South, towards Chelan.
Arrive at the lake resort town of 切兰. Lake Chelan is one of the deepest lakes in the US, and extends 50 miles into the mountains. Private ferries sail all the way up the lake to the remote village of Stehekin in the Lake Chelan National Recreation Area, a popular and worthwhile trip if you have a day to spare.
You may have noticed the orchards in the Columbia Gorge. These are the source of Washington's famous apples, exported around the world. If you come across a fruit stand that's open, make a stop and snack on whatever is in season.
韦纳奇 bills itself "Apple Capital of the World". The 韦纳奇谷博物馆 has great exhibits on the history of the apple industry, and an 11 mile loop trail skirts both sides of the Columbia River. If you're becoming wary of driving, take a calming break at the 欧姆花园.
Stevens Pass Highway
[]
From Wenatchee, take 
US-2 West, the Stevens Pass Highway.
As you drive through the Wenatchee Valley, you will see more of apple orchards this region is famous for. At Cashmere, stop for a tour of the Aplets & Cotlets 糖果坊, where they turn these fruits into delectable treats.
A few miles west, cross into "Bavaria" at the village of 莱文沃思. This mountain town noticed how its steep mountain relief resembled the European Alps, and reinvented itself into the top mountain getaway for Pacific Northwest residents. Enjoy a meal of hearty German fare, and consider making it a base for rafting the Wenatchee River or hiking The Enchantments.
Continue west through the beautiful Tumwater Canyon to Coles Corner. You can turn off to relax at pristine 莱克温纳奇州立公园, or continue on to 史蒂文斯山口, at 4061 feet, a major ski resort and another trailhead to the Pacific Crest Trail. This was, and remains, a crucial rail route through the Cascades. If you're interested in the railroad, the 惠灵顿镇遗址 is the best interpretive site on the topic.
The highway quickly descends into the Skykomish Valley. Take a brief stop to see 欺骗瀑布, then enjoy the dramatic relief of the surrounding mountains, featuring the jagged Mount Index. At the town of Gold Bar, stop for a quick hike at 华莱士瀑布州立公园 to see the 265-foot waterfall.
By Sultan, the mountains mellow out into the foothills of the Puget Sound and the agricultural Snohomish River floodplain. Monroe is the home to the Evergreen State Fair in August and September. You can turn off here to Seattle, or continue on WA-2. If you still have any shopping left to do, 斯诺霍米什 is the regional center for antiques and agrotourism. The highway ends at Interstate 5 in Everett, completing the loop.
