A practical six-day Mount Rainier and Mount St. Helens road trip itinerary from Seattle, with realistic driving legs, the best summer timing, and where to linger on Washington's volcano loop.
Two of the Pacific Northwest's great volcanoes stand within a half-day drive of Seattle, and you can see both on one unhurried week. This Mount Rainier and Mount St. Helens road trip itinerary links the wildflower meadows of Mount Rainier National Park with the still-raw blast zone of Mount St. Helens, all on paved roads and all within a six-day loop.
The loop runs counter-clockwise from Seattle. You head south-east first to Mount Rainier's high north-east corner at Sunrise, cross the park to Paradise on the south-west side, then drop south to Mount St. Helens before returning to Seattle on Interstate 5. Distances are modest, but the mountain roads are slow and scenic, so plan for relaxed driving days.
This is a scenic, nature-led drive with as much hiking as you want to add. It suits travellers who like alpine meadows, big volcano views and short-to-moderate trails, and who are comfortable on winding park roads. Any car copes with the paved routes, and no four-wheel drive is needed.
Six days is the sweet spot: two nights at Mount Rainier's Paradise side, a night each at Sunrise and Mount St. Helens, and Seattle to bookend the trip. With less time, focus on Mount Rainier alone. With more, add a night at Ohanapecosh or in the Columbia River Gorge.
Summer is the only sensible window for the full loop. The Sunrise Road and the Stevens Canyon Road through Mount Rainier open only from around early July to October, and the high meadows peak for wildflowers in late July and August. Mount Rainier has dropped timed-entry reservations for 2026, so no advance permit is needed.
Collect your hire car, stock up, and get a feel for the mountains you are about to circle. On a clear day, Mount Rainier looms over the skyline from Kerry Park.
Drive south-east on SR 410 to the park's north-east side. Sunrise sits at 6,400 feet, the highest point you can reach by car, ringed by wildflower meadows with the Emmons Glacier filling the view. The Crystal Mountain gondola adds an even wider panorama.
Cross the park via the Stevens Canyon Road to Paradise, the classic heart of Mount Rainier. Walk the Skyline Trail through the meadows, visit the historic Paradise Inn, and explore the waterfalls and old-growth forest around Longmire. Base two nights in Ashford, just outside the year-round Nisqually entrance.
Eight days through the finest UNESCO towns of Bohemia and Moravia: Prague's Astronomical Clock, the bone church of Kutná Hora, Telč's Renaissance square, the fairy-tale castle bend of Český Krumlov and Pilsner Urquell in Plzeň.
Head south to Castle Rock and turn up the Spirit Lake Memorial Highway (SR 504) into the 1980 blast zone. Start at the Silver Lake Visitor Center, stop at the Hoffstadt Bluffs overlook, and walk among the debris-avalanche hummocks where the eruption reshaped the land. Note that Johnston Ridge Observatory and the upper highway are closed for bridge repairs until about 2027.
Return north on I-5 to close the loop. On a clear day the drive frames both volcanoes one last time before you reach the city.
Give Mount Rainier the lion's share of your time, split between the Sunrise and Paradise sides so you avoid long back-and-forth drives. Keep the Mount St. Helens day relaxed, as the west-side viewpoints and short trails are easy to combine in an afternoon.
This is a self-drive loop best done in any standard car. Fill up before entering Mount Rainier, as there is no fuel inside the park; Ashford and Packwood are the handiest stops. Carry layers and water, and download offline maps, because mobile signal drops out in the mountains.
Check road status before you travel, as Sunrise, Stevens Canyon and the upper SR 504 are seasonal or under repair. Alpine weather changes fast, so start hikes early and turn back if conditions close in. Wildlife, including bears, lives throughout both areas, so store food properly and keep your distance.
