Regional guide
The Pacific Northwest packs extraordinary variety into its national parks: rainforest and wild coast at Olympic, a glaciated volcano at Mount Rainier, jagged alpine spires at North Cascades, and the deepest, bluest lake in the country at Crater Lake. This guide compares the four.
Short answer
Olympic ranks first for sheer variety, combining rainforest, coast, and alpine ridges, followed by Mount Rainier for its volcano and wildflower meadows, North Cascades for empty alpine grandeur, and Crater Lake for its singular deep-blue caldera. All four are best from mid-summer through early fall, when the high roads and trails are open.
Each pick links to the full park guide with season tables, logistics, packing, and route context.
The variety parkOlympic 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'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.
Open the Mount Rainier guide
Empty alpine grandeurNorth 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.
Open the North Cascades guide
The deep blue calderaCrater Lake is the deepest lake in the United States, filling a collapsed volcano with water of an intense blue, circled by a scenic Rim Drive and rim viewpoints.
Open the Crater Lake guidePlanning notes
Olympic, Mount Rainier, and North Cascades all ring Seattle, so they link into one loop from a single airport. Crater Lake sits well south in Oregon and pairs better with a separate Oregon trip.
This is the only dependable window for full access. The North Cascades Highway, Rainier's high roads, and Crater Lake's Rim Drive are all seasonal and snow-dependent.
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.
The Pacific Northwest's national parks are Olympic, Mount Rainier, and North Cascades in Washington, and Crater Lake in Oregon. The three Washington parks ring Seattle, while Crater Lake sits in southern Oregon.
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 and Crater Lake each have a distinct, dramatic payoff.
Mid-July through September is the reliable window. The North Cascades Highway, Mount Rainier's high roads, and Crater Lake's Rim Drive are all seasonal, and the high country needs the snow to clear, so summer into early fall is when all four are fully open.
Gear keyed to what these parks are for, the tools to size your days and budget, and explainers worth a read before you go.
