Why Road Tripping in Washington Excels

The Evergreen State’s geography is a driver’s dream, with over 7,000 miles of coastline, three national parks, and countless scenic byways. Highways like US-101 and SR-20 wind through varied terrain, offering accessible exploration without excessive crowds. Ideal for 3-14 day journeys, these trips suit families, couples, and solo travelers alike. Spring brings wildflowers, summer perfects hiking, fall colors stun, and winter suits snow enthusiasts.

Epic Olympic Peninsula Loop

Circumnavigate the Olympic Peninsula on US-101 for a 300+ mile circuit showcasing rainforests, beaches, and mountains. Start in Port Angeles, ferry across from Seattle, and immerse in Olympic National Park’s diversity.

• Hurricane Ridge: Drive up for panoramic views of the Strait of Juan de Fuca and subalpine meadows. Short trails like Klahhane Ridge offer wildflowers in summer.
• Sol Duc Valley: Soak in natural hot springs after hiking to Sol Duc Falls, a 1.6-mile easy path through old-growth forest.
• Rialto Beach: Walk to Hole-in-the-Wall sea arch at low tide, spotting sea stacks and driftwood along the wild shore.
• Lake Crescent: Paddle or boat on this deep glacial lake, with Marymere Falls nearby via a shaded 1.8-mile trail.

Extend to Cape Flattery, the northwesternmost point, via SR-112 for dramatic cliffs and tide pools. Camp at Kalaloch or stay in Forks for Twilight fame. Allow 4-5 days; watch for elk and whales.

Mount Rainier Scenic Circuits

Center your trip around Mount Rainier National Park, an active stratovolcano dominating the skyline. Access via SR-706 from Seattle (2 hours) for Paradise and Sunrise areas.

Key hikes include Skyline Trail (5.5 miles, Paradise), a moderate loop with Rainier views at every turn, and Grove of the Patriarchs (1.3 miles, Ohanapecosh) through ancient cedars. Entry fee: $30/vehicle. Best July-September; book lodges early. Side trip to Crystal Mountain for gondola rides.

North Cascades Highway Adventure

SR-20, the North Cascades Highway, cuts through the American Alps from I-5 near Burlington to US-97 near Winthrop (140 miles). This National Scenic Byway features glaciers, turquoise lakes, and jagged peaks.

• Diablo Lake Overlook: Iconic vista of emerald waters backed by colonial peaks; short walk to viewpoints.
• Washington Pass: Highest point on the highway (5,477 ft), with Rainy Pass trails branching to alpine lakes.
• Ross Lake: Boat-accessible reservoir; kayak or hike to Hidden Lake Overlook (9 miles roundtrip, strenuous).
• Heather-Maple Pass Loop: 7.2-mile moderate hike with lake basins and cutthroat peaks.

Stay in Marblemount or Mazama; autumn larch trees glow golden. Open mid-May to November; avalanches close it winters.

San Juan Islands Ferry-Hopping Journey

No car needed initially—ferry from Anacortes to these 172 islands. Focus on San Juan, Orcas, and Lopez for a 50-100 mile watery road trip.

Orcas Island: Hike Mount Constitution (5 miles roundtrip) in Moran State Park for 360-degree Salish Sea views. Rent kayaks at Eastsound.

San Juan Island: Lime Kiln Point Lighthouse for orca watching (summer resident pods), plus English Camp historic site.

Lopez Island: Bike-friendly shores, beaches like Spencer Spit State Park.

Camp or glamp; ferries book fast weekends. Combine with Skagit Valley tulips (April).

Eastern Washington Palouse and Beyond

Cross the Cascades on I-90 or SR-2 to rolling wheat fields of the Palouse Scenic Byway (SR-26/195, 200 miles). Steptoe Butte offers 360-degree panoramas.

• Palouse Falls: Washington’s state waterfall, 198 ft drop; short hike to base.
• Colfax to Pullman: Charming towns, WSU campus, craft breweries.
• Highway 2 East: Leavenworth Bavarian village, Wenatchee apple orchards, Lake Chelan wines.

Harvest season (June-July) paints golden waves; less crowded than west side.
