Olympic National Park vs Mount Rainier National Park: Which Park Should You Visit?

Pick Olympic if you want the full Pacific Northwest sampler — rainforest, coast, and alpine terrain in one park. Pick Rainier if you want a singular, iconic volcanic peak with world-class alpine hiking. The two parks sit roughly three to four hours apart in Washington State, close enough to combine on a longer road trip but far enough that most visitors choose one for their main focus.

Entrance fees and reservation policies are identical for 2026 — $30 per vehicle, no timed-entry system at either park. Your decision comes down entirely to the type of landscape and experience you are after.

If this is your first major Pacific Northwest national park and you have limited days, Olympic covers more ground. A single loop of the park can check off old-growth rainforest at the Hoh, sweeping alpine views from Hurricane Ridge, and dramatic sea stacks at Ruby Beach — three completely different landscapes that would otherwise require three separate parks.

Rainier is one of the most demanding and rewarding hiking destinations in the lower 48. The Paradise area alone draws hikers from across the world for its combination of high-alpine meadows, glacial approach routes, and clear sight lines to the summit. For those chasing elevation and technical challenge, it is the decisive winner.

Olympic's variety is its family superpower. Kids who lose interest in one terrain have two more waiting. The Hall of Mosses at Hoh Rain Forest, easy beach walks at Rialto and Second Beach, and the scenic drive to Hurricane Ridge each offer a completely different experience that keeps younger visitors engaged across multiple days without long or strenuous hikes.

Both parks peak in July and August when parking fills fast and trails hit full capacity. September through early October is the sweet spot at both — trails still open, crowds thinning, and fall conditions beginning. Rainier's usable season is noticeably compressed: tire chains required from November through April cut off casual winter visits, while Olympic's coastal and rainforest areas stay reachable even in winter months.

On paper these two parks cost the same to enter. The real difference appears in overnight stays: Olympic charges $8 per person per night plus a $6 permit fee for wilderness camping, which adds up for groups. Rainier requires backcountry permits year-round, so overnight hikers at either park should plan and budget ahead. Both parks operate cashless at entrance stations.
