From Moss to Ice: A 5-Day Backpacking Traverse Through the Hoh Rainforest to the Blue Glacier
Five days from temperate rainforest to glacial edge—earn the views, respect the elements.
On the first morning, the forest speaks before you do. A damp hush hangs between giant Sitka spruces and western hemlocks, each trunk draped in moss like green shawls. Mist coils through the understory and the Hoh River—dark, quick, and purposeful—slides past as if daring you to follow. Over five days you will, moving from ancient temperate rainforest into subalpine meadows, then up to the stony approaches of Mount Olympus where the Blue Glacier crowns the range. It’s a trip that asks you to trade predictable trails for shifting ecosystems and to meet the Pacific Northwest on its own terms.
Trail Wisdom
Expect Wet Feet
Stream crossings and daily rain are common—wear quick-drying socks and waterproof footwear and pack a small dry bag for electronics.
Layer for Contrast
Temperatures swing from cool, wet rainforest to warm alpine sun—bring breathable base layers and a warm midlayer.
Guard Your Food
Store food in bear-resistant containers or follow guide instructions to minimize wildlife encounters.
Pace the Glacier Day
The approach toward the Blue Glacier is the most strenuous portion—start early and keep a steady, conversational pace.

Conservation Note

The Olympic Peninsula is the ancestral land of several tribes including the Hoh and Quinault, whose cultural ties and practices shaped regional stewardship.
Seasonal Guide
spring
Best for: Wildflower emergence, Fewer crowds
Challenges: Lingering snow at higher elevations, High stream flows
Spring brings verdant rainforest growth and fresh waterfalls, but snowpack can make the upper reaches unpredictable—expect wet, variable conditions.
summer
Best for: Stable trail conditions, Clear glacier views
Challenges: Intermittent storms, Higher visitor numbers
Summer is the optimal season for glacier viewpoints and drier trails, though late-season storms and cool nights still occur.
fall
Best for: Crisp air and clearer light, Smaller groups
Challenges: Earlier snowfall possible, Shorter daylight hours
Fall tightens the weather window—great visibility and solitude, but plan for shorter days and the chance of early snow.
winter
Best for: Snowbound solitude for experienced parties
Challenges: Heavy precipitation and avalanche risk, Trailhead access closures
Winter conditions are harsh and require alpine skills; guided summer-style backpacking is not recommended during this season.

Common Questions
Do I need a wilderness permit?
Yes—overnight backcountry travel in Olympic National Park requires a wilderness permit; guided trips usually secure these for the group—confirm with your operator.
How fit do I need to be?
You should be comfortable hiking 6–10 miles a day with a 30–40 lb pack and able to handle sustained climbs; the guides set a steady pace for mixed-ability groups.
Will I need technical glacier gear?
The standard itinerary reaches a glacier viewpoint and does not require rope teams for most participants; specialized glacier travel is managed by guides if included—confirm before booking.
What wildlife might I see?
Expect deer and elk in meadows and occasional black bear in forested zones—guides enforce food storage and bear-aware practices to reduce risk.
Is cell service available?
Cell coverage is limited through much of the park; treat the trip as low-connectivity and bring downloaded maps and emergency contacts.
What is the cancellation policy?
This operator offers free cancellation per the product flags, but confirm exact timing and refund terms when you book.
What to Pack
Water filter or tablets (clean stream water), Waterproof layers (rain is frequent), Sturdy boots (support on varied terrain), Bear-resistant canister (required for food storage)
Did You Know
The Hoh Rainforest receives more than 100 inches of precipitation annually, creating one of the largest remaining tracts of temperate rainforest in the U.S.
Quick Travel Tips
1) Fly into Seattle-Tacoma and allow 4–5 hours driving to Forks; 2) Download offline maps and emergency contacts before arrival; 3) Reserve wilderness permit or confirm guide handles permits; 4) Pack a small dry bag for electronics and a headlamp with extra batteries.
Local Flavor
After the trail, head into Forks or Port Angeles for fresh Pacific Northwest fare—think Dungeness crab, local oysters, and hearty pub meals paired with regional ales; small cafes in town offer warming soups and trail-friendly sandwiches before or after long days.
Logistics Snapshot
Closest major airport: Seattle-Tacoma International (SEA) / Closest trailhead access: Hoh Rainforest Visitor Center (drive ~3.5–4.5 hours from SEA) / Driving distance from Forks: 30–60 minutes depending on route / Cell service: limited in park / Permits: Wilderness permit required for overnight backcountry
