Road trip guide

Washington three national parks road trip

Washington's three national parks form a loop around Seattle: the volcano at Mount Rainier, the rainforest-and-coast variety of Olympic, and the alpine spires of North Cascades. Together they make a striking Pacific Northwest circuit.

Short answer

Fly into Seattle and loop through Mount Rainier, Olympic, and North Cascades in either direction, returning to Seattle. Budget 7 to 9 days. The reliable window is mid-July through September, when the North Cascades Highway and Rainier's high roads are open and the Olympic high country is clear of snow.

What makes the Washington loop work

  • All three parks ring Seattle, so a single airport handles arrival and departure.
  • Each park is a distinct ecosystem: volcano, rainforest and coast, and alpine, so the variety stays high.
  • A mid-summer-to-early-fall window, since the North Cascades Highway and Rainier's Sunrise road are seasonal.
  • Olympic is large and circled by US 101, so it needs more than one base to see without long backtracks.

The route, day by day

Trip length
7 to 9 days for the three-park loop around Seattle.
Total driving

Mount Rainier

Best for
First 2 days, Paradise wildflower meadows, and the Skyline Trail
Watch
Paradise and Sunrise roads are seasonal and the meadows peak only in mid to late summer. Timed-entry reservations have applied in recent summers, so check the current rule.

Rainier is about 2 to 2.5 hours from Seattle and a strong opener. Base near Paradise for the wildflower meadows and the Skyline loop under the glaciers, then add the Sunrise area on the northeast side.

Olympic

Best for
Days 3 to 5, the Hoh Rain Forest, Hurricane Ridge, and Rialto or Ruby Beach
Watch
The park is big and the coast, rainforest, and ridge are far apart. Plan the loop on US 101 so you are not driving the same stretch twice.

Olympic packs rainforest, alpine ridges, and wild coastline into one park circled by US 101, which is why it earns three nights and two bases. Port Angeles handles Hurricane Ridge; the Forks area handles the Hoh and the beaches.

North Cascades

Best for
Days 6 to 7, Diablo Lake, the North Cascades Highway, and Cascade Pass
Watch
The North Cascades Highway (State Route 20) closes in winter, often from late fall into spring, which makes this park strictly a summer-to-early-fall stop.

North Cascades is about 4 hours from the Olympic Peninsula and closes the loop with jagged peaks and turquoise glacial lakes. The North Cascades Highway through the park is one of the great alpine drives.

Planning notes

Loop from Seattle in either direction

All three parks circle the city, so you can run Rainier first or North Cascades first and still return to one airport. Rainier-then-Olympic-then-North Cascades keeps the longest alpine drive for the end.

Give Olympic two bases

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 Rain Forest 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 the Olympic high country needs the snow to clear.

Check Rainier's entry rules before you go

Mount Rainier has used timed-entry reservations for its busy corridors in recent summers. Confirm the current season's rule on the park page so a reservation gap does not cost you a Paradise morning.

Frequently asked questions

Can you visit all three Washington national parks in one trip?

Yes. Mount Rainier, Olympic, and North Cascades all ring Seattle, so you can fly into one airport and loop through all three over 7 to 9 days, returning to where you started.

What is the best order for a Washington national parks road trip?

A common loop is Mount Rainier, then Olympic, then North Cascades, returning to Seattle. Either direction works since the parks circle the city, but saving North Cascades for last keeps the great alpine highway drive as a finale.

When is the best time for a Washington three-park road trip?

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.
