Learn more about the big three national parks in Washington, including what makes each one special and tips for planning your visit.
Overview of Washington's National Parks
Washington State is home to three designated national parks, each offering a unique glimpse into the state’s diverse natural beauty. Managed by the National Park Service (NPS), these parks are preserved for their ecological significance, cultural heritage, and recreational opportunities. The three national parks in Washington include Olympic National Park, Mount Rainier National Park, and North Cascades National Park.
Olympic National Park
Located on the Olympic Peninsula in northwestern Washington, Olympic National Park encompasses nearly one million acres and is celebrated for its extraordinary ecological diversity. The park includes glacier-capped mountains, old-growth temperate rainforests, and over 70 miles of wild Pacific coastline. It’s designated both a UNESCO World Heritage Site and an International Biosphere Reserve. Popular points of interest include Hurricane Ridge, the Hoh Rain Forest, and Rialto Beach.
Mount Rainier National Park
Established in 1899, Mount Rainier National Park is centered around its namesake, Mount Rainier — a 14,410-foot stratovolcano and the highest peak in the Cascade Range. The park spans over 236,000 acres and features subalpine meadows, ancient forests, and more than 25 major glaciers. Visitors often explore areas such as Paradise, Sunrise, and the Wonderland Trail, a 93-mile loop encircling the mountain.
North Cascades National Park
North Cascades National Park is part of the larger North Cascades National Park Complex, which also includes Ross Lake and Lake Chelan National Recreation Areas. Known for its rugged alpine terrain and over 300 glaciers — the most of any U.S. park outside Alaska — this park is a haven for backcountry adventurers. While the park itself is largely undeveloped, nearby scenic drives and overlooks on Highway 20 (North Cascades Highway) provide accessible views.
Key Statistics
- Number of National Parks in Washington: 3
- Total Acreage (Combined): Over 2.1 million acres
- Most Visited Park: Olympic National Park, with over 2 million visitors annually
- Oldest Park: Mount Rainier National Park (established in 1899)
- Least Visited Park: North Cascades National Park, due to its remote and undeveloped landscape
These national parks reflect Washington’s vast ecological range — from coastal tidepools and moss-covered forests to volcanic peaks and glacial valleys. Each park offers a distinct experience, contributing to the state's reputation as a premier destination for nature lovers and outdoor enthusiasts.

Visitor Statistics and Access
Annual Visitor Numbers
Washington State is home to three official national parks: Olympic National Park, Mount Rainier National Park, and North Cascades National Park. Together, these parks welcome millions of visitors each year, making them some of the most visited natural destinations in the Pacific Northwest.
- Olympic National Park is consistently among the top 20 most-visited national parks in the United States, attracting over 2.5 to 3 million visitors annually. Its diverse ecosystems—from temperate rainforests to rugged coastlines—draw tourists year-round.
- Mount Rainier National Park typically sees around 1.5 to 2 million visitors per year. The summer months are particularly popular due to accessible hiking trails and wildflower blooms in the subalpine meadows.
- North Cascades National Park, despite its stunning alpine scenery, remains one of the least visited national parks in the U.S., with annual visitor numbers averaging under 40,000. Its remote location and limited road access contribute to its lower traffic, preserving its wilderness character.
These figures can vary year to year depending on weather conditions, wildfire activity, and road accessibility. The National Park Service (NPS) provides annual visitation reports that detail trends and help guide park management decisions.
Accessibility and Transportation
Each of Washington’s national parks has unique access points and transportation considerations:
-
Olympic National Park is accessible via U.S. Highway 101, which loops around the Olympic Peninsula. The park can be reached from Seattle via ferry and car in approximately 2.5 to 3 hours. Major entrances include Port Angeles, Hoh Rain Forest, and Lake Quinault.
-
Mount Rainier National Park has multiple entry points, with the Nisqually Entrance near Ashford being the most popular. This park is about a 2-hour drive from Seattle or Tacoma. Seasonal road closures, especially at the Sunrise and Paradise areas, are common due to snow and should be checked in advance.
-
North Cascades National Park is accessed primarily through State Route 20 (North Cascades Highway), which is typically open from late spring through early fall. The route offers scenic views and access to trailheads, but there are no direct roads into the park’s core wilderness area, requiring backcountry travel.
Seasonal Access Considerations
While the parks are generally open year-round, access can vary significantly with the seasons:
- Winter brings heavy snowfall to Mount Rainier and parts of Olympic, resulting in partial road closures but offering opportunities for snowshoeing and cross-country skiing.
- Spring and summer are the peak seasons for all three parks, with most roads, visitor centers, and campgrounds open and accessible.
- Fall offers fewer crowds and vibrant foliage, especially in North Cascades, but weather conditions can change rapidly.
Visitors are encouraged to check the National Park Service's official websites for each park for current conditions, road closures, and alerts before planning their trip.
Entry Fees and Passes
All three national parks charge entrance fees, which help fund maintenance and conservation efforts:
- Olympic National Park: $30 per vehicle (valid for 7 days)
- Mount Rainier National Park: $30 per vehicle (valid for 7 days)
- North Cascades National Park: Free entry, although fees may apply for certain services in the surrounding Ross Lake and Lake Chelan National Recreation Areas
For frequent visitors, the America the Beautiful Annual Pass ($80) offers unlimited access to all national parks and federal recreation lands for one year.
Visitor Facilities and Accessibility
Each park features a network of visitor centers, restrooms, and accessible facilities:
- Olympic’s Hurricane Ridge Visitor Center and Hoh Rain Forest Visitor Center provide ranger-led programs and accessibility resources.
- Mount Rainier’s Paradise Jackson Visitor Center is fully accessible and offers exhibits, restrooms, and panoramic views.
- North Cascades’ Visitor Center near Newhalem provides interpretive displays, trail information, and accessibility details.
Efforts are ongoing to improve accessibility for all visitors, including paved trails, wheelchair-accessible viewpoints, and audio-visual exhibits for the hearing and visually impaired.
Best Times to Visit
Washington’s national parks—Mount Rainier, Olympic, and North Cascades—each offer distinct experiences depending on the time of year. In general, the best time to visit is from late spring through early fall (May to October), when most park roads, trails, and visitor services are fully operational.
- Summer (June to August): This is the most popular time for visitors, offering the best weather, clear trails, and abundant wildflowers. Expect larger crowds, especially in Mount Rainier and Olympic National Parks.
- Fall (September to October): Cooler temperatures and fewer crowds make this a great time to explore, especially for photography and wildlife viewing. Some high-altitude trails may begin closing due to snow.
- Spring (April to May): Lower elevations begin to thaw, and waterfalls are at their peak due to snowmelt. However, higher elevation areas may still be snow-covered.
- Winter (November to March): While many roads and facilities close during winter, snowshoeing and cross-country skiing are popular in Mount Rainier and North Cascades. Be prepared for road closures and limited services.
Accommodation Options
Each park offers a range of accommodations to suit different travel styles and budgets.
-
Within the Parks:
- Lodges: Historic lodges such as Paradise Inn (Mount Rainier) and Lake Crescent Lodge (Olympic) provide rustic charm and proximity to key attractions. These often require reservations months in advance.
- Campgrounds: All three parks have developed campgrounds, some of which can be reserved through recreation.gov, while others operate on a first-come, first-served basis.
- Backcountry Camping: Permits are required for overnight stays in the backcountry. This option is ideal for experienced hikers seeking solitude.
-
Nearby Towns:
- Options range from motels and inns to vacation rentals in gateway communities like Ashford (Mount Rainier), Port Angeles (Olympic), and Marblemount (North Cascades).
