Washington packs an unusual amount into a three hour radius of Seattle: a temperate rainforest, a 4,392 metre active volcano, a Pacific coastline, an island archipelago and, over the Cascades, a desert with a serious wine industry.
The catch is timing. The western half of the state is genuinely wet for eight months of the year, the mountain roads open late, and Mount Rainier spends much of the year invisible behind cloud. Locals say “the mountain is out” as a weather report, and it is one, because it is not out most days.
The quick answer
How long: three days for Seattle. Seven to add Olympic and Rainier, ten for the San Juans as well.
Best months: July to September, and it is not close. This is the driest and only reliably clear window.
None of Washington’s national parks are on the 2026 international visitor surcharge list. Olympic, Mount Rainier and North Cascades all charge standard fees only.
Mount Rainier no longer requires timed entry reservations after the National Park Service ended most reservation systems for 2026. Arrive early anyway, because parking at Paradise and Sunrise fills.
San Juan Islands ferries take vehicle reservations and summer sailings book out. Go as a foot passenger if you can.
Mountain roads open late. Hurricane Ridge, Sunrise and the North Cascades Highway are typically snowbound until late June or July.
Daily budget: roughly $200 to $290 per person mid-range in Seattle, less elsewhere.
Seattle
Pike Place Market is the obvious stop and better early, before the fish-throwing crowd. The lower levels and the surrounding blocks are where the actual food is.
The Space Needle and Chihuly Garden and Glass sit together at Seattle Center. The glass is the better of the two and holds up regardless of the weather.
The Museum of Pop Culture, in a Frank Gehry building next door, covers music, science fiction and video games and is more serious than it sounds, particularly on Seattle’s own musical history.
The waterfront has been rebuilt following the removal of the elevated viaduct, and the ferries across Puget Sound to Bainbridge Island are the cheapest good views in the city.
Neighbourhoods. Capitol Hill for bars and restaurants, Ballard for the locks and a Sunday market, Fremont for oddities, the International District for the best food in the city.
Coffee is taken seriously to a degree that is not a cliché. The original Starbucks at Pike Place is a queue for a photograph, and there are far better roasters within a few blocks.
The three national parks
Olympic National Park is really three parks in one, and this is what makes it exceptional. The Hoh Rain Forest gets over three metres of rain a year and looks like it. Hurricane Ridge, an hour up from Port Angeles, gives alpine views across to Canada. And Rialto, Ruby and Second Beach on the Pacific coast have sea stacks, driftwood and tide pools. Driving the full loop around the peninsula takes two days minimum, three to do it properly.
Mount Rainier National Park is built around an active volcano that is also the most glaciated peak in the contiguous states. Paradise on the south side has the wildflower meadows, peaking from late July into August, and Sunrise on the north east is higher, drier and opens later, typically early July. Timed entry reservations are not required for 2026, though parking fills by mid-morning in season.
North Cascades National Park is the least visited of the three and the most rugged, with more glaciers than anywhere in the country outside Alaska. Highway 20 through the park closes for winter, usually from November until April or May. Diablo Lake’s turquoise colour comes from glacial rock flour.
The rest of the state
The San Juan Islands, reached by ferry from Anacortes, are the calm side of Washington and sit in a rain shadow, so they get noticeably less rain than Seattle. San Juan Island for Friday Harbor and whale watching, Orcas Island for Mount Constitution and hiking, Lopez for cycling. Vehicle reservations on summer sailings are essential and sell out.
Leavenworth, two hours east, is a Bavarian-themed town that leans into it entirely and is either delightful or exhausting. It is genuinely spectacular in December.
The Palouse, in the far south east, is rolling farmland that looks like a green and gold sea in late spring, and it is the most photographed landscape in the state that nobody outside it has heard of.
Walla Walla and the Yakima Valley east of the Cascades have become a serious wine region, particularly for Cabernet Sauvignon and Syrah. The climate over there is desert, with hot dry summers and real sunshine.
Mount St Helens, two hours south of Seattle, still shows the 1980 eruption clearly. The Johnston Ridge Observatory road has had access issues in recent years, so check the current status.
When to go
July to September is the season, and the gap between it and everything else is larger here than in most states. Dry, warm, long days, mountain roads open and wildflowers at Rainier from late July.
June is variable and much of the high country is still under snow.
October brings the rain back but also autumn colour in the Cascades and much lower prices.
November to May is grey and wet on the western side, with drizzle rather than downpours. Seattle actually receives less total rainfall than New York, but across far more days, which is what people remember. Skiing at Crystal Mountain and Stevens Pass runs through this period, and the eastern half of the state stays sunny and cold.
What it costs
Accommodation: $200 to $320 a night mid-range in Seattle in summer, dropping by a third in winter. $140 to $220 on the Olympic Peninsula and $180 to $300 in the San Juans in season.
Park entry: $30 per vehicle for seven days at Olympic, Mount Rainier and North Cascades, with no international surcharge at any of them.
Ferries: Washington State Ferries take vehicles and foot passengers, with fares by route. Summer vehicle sailings to the San Juans need reservations well ahead. Foot passenger travel needs none.
Car hire: $55 to $85 a day. You need one for everything outside Seattle.
Eating: $18 to $26 for a casual meal, $45 to $80 per person for dinner. Washington has no state income tax and a high sales tax, added at the till.
A route that works
Seven days. Three nights Seattle, then a loop of the Olympic Peninsula for three, ending with a night near Mount Rainier.
Ten days. Three nights Seattle, three on the Olympic Peninsula, two in the San Juans, two at Mount Rainier.
Eastern version. Seattle, Leavenworth, then over the Cascades to Walla Walla and the Yakima Valley for wine, which is a completely different climate and a much cheaper trip.
Practical notes
Mountain road opening dates vary by a month year to year. Hurricane Ridge, Sunrise and Highway 20 through the North Cascades are all seasonal, and checking before you build a day around them is not optional.
The Pacific coast beaches are for looking at, not swimming. The water is cold all year and there are strong currents and drift logs that move in the surf.
Tide tables matter on the Olympic coast, where several beach walks are only passable at low tide and people get cut off.
Seattle traffic is worse than the city’s size suggests, because the water constrains where roads can go. Interstate 5 through downtown is slow for much of the day.
Ferry queues without a reservation on a summer weekend can mean waiting for two or three sailings. Arrive early or walk on.
Frequently asked questions
What is the best time to visit Washington State?
July to September, without much competition. It is the driest, warmest and clearest window, the mountain roads are open, and Rainier’s wildflowers peak from late July. The rest of the year is grey and wet on the western side, though the east stays sunny.
Does Mount Rainier require a reservation in 2026?
No. The National Park Service ended most timed entry systems for 2026 and Rainier is among them. Parking at Paradise and Sunrise still fills by mid-morning in summer, so arriving early remains the practical advice.
Do foreign visitors pay the $100 surcharge in Washington?
No. Olympic, Mount Rainier and North Cascades are not among the eleven parks charging the additional international visitor fee from 1 January 2026. Standard entry of $30 per vehicle applies to everyone.
How many days do you need for Olympic National Park?
Two minimum and three to do it properly, because it is three separate environments spread around a large peninsula: the Hoh Rain Forest, Hurricane Ridge in the alpine, and the Pacific beaches. The full loop is a long drive.
Do I need a ferry reservation for the San Juan Islands?
For a vehicle in summer, yes, and sailings sell out well ahead. As a foot passenger you can turn up, which is the easier way to do it if you are staying in one town or hiring a bike on arrival.
Does it really rain that much in Seattle?
It rains on many more days than most American cities but the total is lower than New York’s, because it arrives as long drizzle rather than downpours. The pattern runs roughly November to May, and summers are genuinely dry and sunny.
When can you see Mount Rainier’s wildflowers?
Late July into August at Paradise, though the exact peak depends on how quickly the snowpack melts. Sunrise on the north east side opens later, usually early July, and stays cooler and drier.
Is eastern Washington worth visiting?
Yes, and it surprises people. Over the Cascades the climate turns to desert, with hot dry summers and reliable sun. Walla Walla and the Yakima Valley make serious wine, and the Palouse farmland in late spring is the best landscape in the state that nobody photographs.
How much does a Washington trip cost?
Roughly $200 to $290 per person per day mid-range in Seattle in summer, dropping by around a third in winter, and less on the peninsula. Car hire is unavoidable outside the city, and ferry fares add up if you take a vehicle to the islands.
