Washington's national parks
Washington has three national parks, and together they form one of the most varied trios in the country: a glaciated volcano at Mount Rainier, the rainforest-and-coast diversity of Olympic, and the jagged alpine spires of North Cascades. All three ring Seattle. This guide compares and ranks them.
Short answer
Olympic ranks first for sheer variety, combining rainforest, coast, and alpine ridges, followed by Mount Rainier for its volcano and wildflower meadows and North Cascades for empty alpine grandeur. All three are best from mid-summer through early fall, when the high roads and trails are open.
How Washington's parks were ranked
- Scenic payoff and the range of landscapes each park offers.
- Ease of access, lodging, and how forgiving the logistics are.
- Crowd levels, since one of these parks stays surprisingly quiet.
- Seasonal window, since the high roads and passes are seasonal.

The variety parkOlympic
- Best for
- The Hoh Rain Forest, Hurricane Ridge, and wild beaches
- Watch
- The park is big and the coast, rainforest, and ridge are far apart, so plan the loop on US 101 and use more than one base to avoid backtracking.
Olympic is three parks in one, packing temperate rainforest, alpine ridges, and rugged coastline into a single park circled by US 101, which is why it tops the list.

The volcanoMount Rainier
- Best for
- Paradise wildflower meadows and the Skyline Trail
- Watch
- Paradise and Sunrise roads are seasonal and the meadows peak only briefly. Timed-entry reservations have applied in recent summers, so check the current rule.
Mount Rainier's glaciated peak towers over subalpine meadows that bloom in mid-to-late summer, with the Paradise and Sunrise areas offering the classic views and hikes.

Empty alpine grandeurNorth Cascades
- Best for
- Diablo Lake, the North Cascades Highway, and high passes
- Watch
- The North Cascades Highway (State Route 20) closes in winter, often from late fall into spring, which makes this strictly a summer-to-early-fall stop.
North Cascades rivals Glacier for jagged peaks and turquoise glacial lakes, yet stays one of the least visited parks in the lower 48 because much of it is rugged wilderness.

Loop all three from Seattle
Mount Rainier, Olympic, and North Cascades all ring Seattle, so they link into one loop from a single airport over about a week.
Give Olympic more than one base
Olympic is large and its rainforest, coast, and alpine ridge sit far apart around US 101. Split nights between Port Angeles for Hurricane Ridge and the Forks area for the Hoh and the beaches.
Go mid-July through September
This is the only dependable window for full access. The North Cascades Highway and Rainier's high roads are seasonal and snow-dependent, so summer into early fall is best.
Frequently asked questions
How many national parks are in Washington?
Washington has three national parks: Mount Rainier, Olympic, and North Cascades. All three ring Seattle, and together they cover volcano, rainforest and coast, and alpine landscapes.
What is the best national park in Washington?
Olympic is usually ranked first for its rare variety of rainforest, coast, and alpine in one park. Mount Rainier is the standout for its volcano and wildflower meadows, while North Cascades offers empty alpine grandeur.
When is the best time to visit Washington's national parks?
Mid-July through September is the reliable window. The North Cascades Highway and Mount Rainier's high roads are seasonal, and Olympic's high country needs the snow to clear, so summer into early fall is when all three are fully open.
