The North Cascade Loop
This loop passes through some of the most spectacular and diverse scenery in Washington around and in the North Cascades Mountains. All roads on this road are paved and well-maintained. The North Cascades Hwy. is closed in winter, making this loop only passable during the summer months.
While doing a day-trip on this loop is theroetically possible, it would not be a good idea because you would have no time at all to stop and enjoy the scenery. Two days is probably the bare minimum, but three to four days would allow you to explore this loop in much better detail. Driving is the only way to experience this loop.
Seattle is the main gateway to this loop. It has an international airport, a train station served by three Amtrak routes and is well connected to the rest of the US by road. From Seattle, the city of Everett, which for our purposes is the starting point of the loop, is less than an hour away by road.
For our purposes, the city of Everett will be our starting point and the description of the loop will go clockwise from there. The loop has been divided into eight sections.
Whidbey and Fidalgo Islands
From Everett, drive west on WA-526 to Mukilteo, and catch the ferry across Possesion sound to Whidbey Island (Clinton). Whidbey Island is one of the longest islands in the continental USA and is also one of the most scenic. As you drive north on WA-525 and WA-20, the main road running along the spine of the island, you pass through pastoral countryside and cute little towns such as Langley and Coupeville, as well as Fort Ebbey State Park. At the north end of the island is the beautiful Deception Pass State Park, which includes land on both Whidbey and Fidalgo Islands bordering Deception pass which divides those mountains. There are beaches, freshwater lakes and the majestic Deception Pass bridge towers over it all. Take the bridge across to Fidalgo Island. Anacortes, on Fidalgo Island is the ferry terminal to the San Juan Islands and a wonderful (overnight) side trip can be taken there from Anacortes.
The Skagit Valley
From Fidalgo Island, the route takes Hwy. 20 east across the Swinhomish Channel to the mainland in the Skagit Valley. This fertile valley is famous for its tulips and claims to grow more of these flowers than Holland. The colorful town of La Conner is just off the highway and can be another side trip. Hwy 20 continues to speed through Burlington (Washington) and Sedro-Wooley, the gateway to North Cascades National Park, where there is a park information center. As the Skagit Valley melts away, the imposing North Cascade mountains come into view.
The North Cascades Highway
At Concrete, a US Forest Service Spur leads to Baker Lake, just east of Mount Baker. This reservoir is popular for hiking, canoeing and angling. Back on the highway, Rte. 20 passes through Rockport State Park and the Skagit River Bald Eagle Natural Area. Continuing on the highway, stop at the Gorge Creek Falls, and then you reach the crystalline Diablo Lake and Ross Lake, both large resivoirs. After Ross Lake, the beautiful North Cascades Hwy. climbs up to Rainy pass (4855') which is a wonderful viewpoint for the area and where a paved trail leads to Rainy Lake. The road ascends even higher up to Washington Pass (5477'), the highest point on this loop. After Washington Pass, the highway snakes down the slope down to the Methow Valley.
The Methow Valley
As the North Cascades Hwy. descends into the Methow Valley, you pass through the cute western town of Winthrop which still seems to have retained the flavor of the frontier. Winthrop is also an outdorsy place: with 300 days of sunshine, all forms of recreation are here. Nearby is the Pearrygin Lake State Park. After leaving Winthrop, the route follows the Methow river first on WA-20, then switching onto WA-153 south down the lower Methow Valley toward the Columbia River.
The Columbia River
The Columbia River is the most important and grandest river of the Northwest, and the drive follows it for quite some time. At Pateros, take US 97 south and soon you will arrive at Lake Chelan, which is one of the deepest lakes in the US. It extends well into the Cascade mountains. Although the southern end of the lake is like a resort, an unusual adventure is to take a ferry or floatplane from the town of Chelan all the way up the lake to remote Stehekin in the Lake Chelan National Recreation area. From Chelan, the loop continues to go along the west side of the Columbia River on US 97-A and soon reaches Wenatchee, which is often regarded as the "Apple Capital of the World". While in Wenatchee, visit the Ohme gardens, a beautiful retreat.
The Wenatchee Valley
At Wenatchee, take US 2 west (the Stevens Pass Hwy)along the Wenatchee Valley. At Cashmere, you can stop by the Aplets and Coltets factory where they make delectable fruit treats or visit a pioneer village. A few miles west, the town of Leavenworth reinvented itself into a charming Bavarian village and is now a top tourist destination. Just outside Leavenworth, there are endless possibilities for outdooor activities especially rafting the Wenatchee River in summer. Continuing west, the drive passes through the beautiful Tumwater canyon to Coles Corner, where a road leads to pristine Lake Wenatchee State Park.
The loop goes back into the Cascade Mountains through Stevens Pass on US-2. At 4061', it is a great viewpoint as well as as a ski resort. Descending from Stevens Pass, stop at Deception Falls on the way. The jagged Mount Index can also be seen from the highway. At Sultan, the mountains mellow out into the Skykomish Valley.
At the town of Gold Bar, be sure to stop at Wallace Falls state park. The center of his park is the 265-foot waterfall, accessed by a trail. The highway rejoins the Puget Sound at the port city of Everett, which is also the end of the loop.
After you pass Marblemount on the North Cascades Highway, there is no gas for 70 miles until Mazama.
