Key Waypoints
Seasonal Weather
Summers (June-August) are typically warm to hot and dry, especially in Eastern Washington, with cooler temperatures in the Cascades. Spring (April-May) and Fall (September-October) offer mild, pleasant weather ideal for driving and outdoor activities, though mountain passes can see early snow. Winters (November-March) bring significant snow to the Cascades and cold temperatures across the state, making driving challenging.
Road Conditions
Interstate 90, the primary route, is well-maintained but requires vigilance, especially over Snoqualmie Pass during winter months where chains or traction tires may be required. Eastern Washington roads are generally flat and straight, but can be remote with limited services; always ensure your fuel tank is adequate. Speed limits are typically 70 mph on I-90, reducing in towns and scenic areas.
Essential Packing
- Layered clothing
- Comfortable walking shoes
- Reusable water bottle
- Camera and extra battery
- Sunscreen and hat
- Road trip snacks
Where to Stay
In Leavenworth, book themed Bavarian hotels well in advance, especially during festivals. Near Grand Coulee Dam, smaller motels are available in towns like Grand Coulee or Coulee City. In Spokane, consider hotels downtown near Riverfront Park for easy access to attractions, or in the vibrant South Hill neighborhood for a quieter stay.

Insider Driving Tips
**Check Mountain Pass Conditions:** Before heading out, especially outside of summer, always check the Washington State Department of Transportation (WSDOT) website for Snoqualmie Pass (I-90) conditions. Weather can change rapidly, and chain requirements or closures are common in colder months.
**Pack for All Seasons:** You'll traverse diverse climates on this trip. Seattle can be damp, the Cascades chilly and snowy, and the Columbia Basin hot and dry. Bring layers, rain gear, sunscreen, and plenty of water to be prepared for anything.
**Fuel Up Strategically:** While major towns have gas stations, stretches through the Columbia Basin can be quite remote. Plan your fuel stops in larger towns like Cle Elum, Wenatchee, or Moses Lake to avoid being caught short.
**Embrace the Detours:** Some of the best experiences are found just off the main highway. Don't be afraid to take a scenic bypass or explore a small town that catches your eye; often, these are where the true hidden gems lie.
**Stay Hydrated & Sun-Safe in the Basin:** The eastern side of the Cascades is significantly drier and sunnier. Always carry extra water, wear a hat, sunglasses, and high-SPF sunscreen, especially if you plan on hiking or spending extended time outdoors.
