The Ultimate West Coast National Parks Road Trip: Los Angeles to Seattle Through 11 National Parks

Planning a West Coast national parks road trip sounds simple enough at first. Fly into Los Angeles. Drive north. Visit some national parks. Finish in Seattle. Then you start actually planning it. Suddenly you’re trying to figure out which Pinnacles entrance to use, whether Yosemite lodging is already sold out, when Lassen’s roads open, whether Fern Canyon needs a reservation, how long it really takes to get from Crater Lake to Mount Rainier, whether Paradise and Sunrise can realistically fit into one day, and how on earth Olympic National Park is supposed to work when everything is hours apart. That’s why this is one of our favorite road trips in the country — but also one of the easiest to underestimate. A well-planned route can take you from the desert landscapes of Joshua Tree to giant sequoias, Yosemite’s granite cliffs, Northern California’s ancient redwoods, Crater Lake’s impossibly blue water, and finally the glacier-covered mountains and rainforests of Washington. And you can connect 11 national parks across California, Oregon, and Washington in one incredible one-way trip from Los Angeles to Seattle.

One of the biggest mistakes with a road trip this large is simply looking at a map and connecting dots without considering park entrances, mountain roads, seasonal closures, and where your next destination actually sits. For example, Pinnacles fits naturally between Sequoia/Kings Canyon and Yosemite, while Lassen → Redwood → Crater Lake creates a much cleaner northern California/Oregon progression than bouncing back and forth across the state. Pacific West Road Trip 11 Natio… That routing decision alone can save you hours of unnecessary driving. How Long Do You Need for This Road Trip? We would not try to rush this trip. Our primary version is 24 days, while the more comfortable option is 28 days. Pacific West Road Trip 11 Natio… Could you technically do it faster? Probably. Would we recommend it? Not really. You’re covering roughly 2,400–2,600 miles of core driving before adding all of your in-park driving. Pacific West Road Trip 11 Natio… And some of these national parks are huge. Olympic alone can involve hours of driving between Hurricane Ridge, Lake Crescent, Hoh Rain Forest, and the coast. Mount Rainier’s Paradise and Sunrise areas are not next door to each other. North Cascades can mean completely different days depending on whether you’re driving Highway 20 or hiking Cascade Pass. This trip works best when you stop treating driving days as wasted days and start building them into the itinerary intentionally. Our recommendation If this is your first time attempting the full route: 24 days: ambitious, but realistic with good planning. 28 days: better if you’re traveling with kids, want more hiking, prefer slower mornings, or simply don’t enjoy feeling rushed. When Is the Best Time to Do a West Coast National Parks Road Trip? This is where things get complicated. There is no perfect month for all 11 parks. Joshua Tree wants cooler weather. Mount Rainier, North Cascades, Lassen, Crater Lake, and other high-elevation areas generally need warmer weather for full road and trail access. That creates the central planning problem of the entire trip. Pacific West Road Trip 11 Natio… Late spring May through June can be a great balance. You may get: More comfortable desert temperatures Strong Yosemite waterfalls Spring wildflowers Fewer peak-summer crowds But some high-elevation roads and trails can still be snow-covered or closed. Mid-summer July and August offer your best odds for full mountain access. But Joshua Tree can be brutally hot, and wildfire smoke becomes a much bigger concern across the West. Early fall September can be fantastic. Mountain roads are typically still accessible, crowds begin to ease, and Joshua Tree starts cooling down. But early winter weather can arrive surprisingly quickly in the Cascades. We personally like the idea of late spring or early fall, but your ideal dates depend heavily on which parks matter most to you. Planning around 11 parks is where this trip gets tricky. Our premium guide includes the full seasonal strategy, 2026 road-access considerations, current-condition planning, reservation timelines, and backup plans for weather and closures. 👉 [GET THE FULL 2026 ROAD TRIP GUIDE] The 11 National Parks on This Route 1.
