Best national parks near Seattle

The Pacific Northwest is home to some of North America’s most spectacular wilderness – from snow-capped volcanoes and moss-covered rainforests to mountain-ringed lakes, wildflower-filled meadows and wave-battered beaches. 

And when it comes to exploring the region’s national parks, few experiences rival the freedom of a road trip. Starting from Seattle, the gateway city of the PNW, travellers can set out on scenic drives and discover picturesque ferry crossings, winding mountain highways and charming small towns along the way.

Mount Rainier National Park 

Best time to visit: July-September 

Towering above the Seattle skyline, Mount Rainier is Washington state’s defining natural landmark. A two-hour drive from the city, the national park surrounding this active volcano is best known for its wildflower-filled meadows in summer, glacier-fed waterfalls and panoramic mountain trails. 

Paradise and Sunrise are the park’s two busiest areas, both offering easy access to hiking routes and viewpoints, while quieter corners reveal old-growth forests and river valleys. The Skyline Trail is one of the park’s signature hikes, particularly during peak wildflower season.  

Day trips are possible, but it’s worth camping there overnight. Summer weekends are famously crowded, so early starts are essential. 

Olympic National Park 

Best time to visit: June-September 

One of the most ecologically diverse national parks in the United States, Olympic National Park has it all: untamed beaches, snow-capped mountains, hot springs and ancient rainforest ecosystems, all within a single protected area. The Hoh Rain Forest is the park’s headline attraction, where moss-draped trees and dense greenery create an almost prehistoric atmosphere. 

Along the coast, windswept Ruby Beach and Shi Shi Beach are scattered with dramatic sea stacks and driftwood. Other highlights include Hurricane Ridge for mountain views, Lake Crescent for kayaking and Sol Duc Hot Springs for steamy soaks.  

While some visitors tackle the park as a long day trip from Seattle via ferry or road (it typically takes three to four hours), Olympic is best experienced over several days due to the long driving distances between its different regions. Port Angeles is the main gateway town for accommodation and supplies. 

North Cascades National Park 

Best time to visit: July-October 

North Cascades National Park has breathtaking high-country scenery, without the bustling crowds of Mount Rainier or Olympic. Located just over two hours’ drive from Seattle, the park is famous for glacier-covered peaks, turquoise lakes and rugged wilderness landscapes. 

Popular hikes include Maple Pass Loop, Blue Lake and Cascade Pass, while scenic pull-offs along the North Cascades Highway boast sweeping views over Diablo Lake and Ross Lake.  

The park is particularly popular with experienced hikers and backpackers looking for a more remote feel, though there are plenty of shorter scenic walks accessible to casual visitors during the snow-free summer and early autumn months. And like Mount Rainier and Olympic, you’ll get far more out of the experience by camping or spending a night nearby. 

San Juan Islands 

Best time to visit: May-September 

While technically not a national park, the San Juan Islands are still one of the area’s premier outdoor destinations, with quaint harbour towns and unspoiled coastal landscapes spread across more than 170 islands. Orcas Island and San Juan Island are the most popular, pairing small-town charm with hiking trails, beaches, whale watching tours and sea kayaking. 

Summer is peak orca season, while spots like Roche Harbor and Friday Harbor draw visitors with myriad galleries, cafés and waterfront restaurants. Historical sites such as English Camp and American Camp also offer insight into the unusual 19th-century Pig War territorial dispute between Britain and the United States. 

It’s possible to squeeze the islands into a day trip from Seattle via ferry or seaplane, but with so many cosy inns, cottages, farm stays and waterfront resorts, you’ll likely want to stay longer. 

The Enchantments 

Best time to visit: late July-October 

Around a four-hour drive east of Seattle, The Enchantments – part of Washington’s Alpine Lakes Wilderness near Leavenworth – are widely considered among the state’s most iconic hiking destinations. The landscape is defined by crystal-clear lakes, jagged granite peaks and roaming mountain goats, while autumn transforms the region as golden larch trees light up the mountainsides. 

Overnight camping permits are competitive, so many hikers now attempt this place as a gruelling single-day trek. There’s also the option of shorter routes to places like Colchuck Lake, which delivers equally dramatic scenery without the same level of commitment. 

And be sure to check out Leavenworth. This Bavarian-style mountain town leans into its alpine identity, complete with beer gardens, timbered lodges and even familiar chains like Starbucks adopting a playful Bavarian makeover. 

Mount St Helens National Volcanic Monument 

Best time to visit: May-October 

Three hours south of Seattle, Mount St Helens National Volcanic Monument offers a different landscape, one shaped by volcanic destruction and recovery. The monument protects the site of the catastrophic 1980 eruption, the deadliest volcanic event in US history. Visitor centres and observatories explain the science and history behind the eruption, while viewpoints reveal the volcano’s still-visible crater and blast zone.  

Hiking trails range from easy lava-field walks to strenuous summit climbs that require permits. Nearby Gifford Pinchot National Forest and Seaquest State Park add forest scenery, lakes and campgrounds with facilities. Make this a long day trip from Seattle, or stay overnight to fully enjoy this historic marvel.
