Pacific Northwest forest is the wettest temperate environment in the United States. The Hoh Rainforest gets 12-14 feet of rainfall a year. Even in summer, expect mist, fog, and surprise downpours. Pack for damp; you'll be glad you did.
The non-negotiables
- Hard-shell rain jacket — three-layer fabric (Gore-Tex Pro, eVent, or equivalent), taped seams, pit zips. Not a packable wind shell. A real rain jacket.
- Synthetic-fill insulating layer — down loses 60% of its loft when wet. Synthetic stays warm even when damp. Yes, it's heavier. Worth it here.
- Waterproof boots with high cuffs (above the ankle).
- Rain pants — not optional in PNW old-growth. Brush stays wet for days after rain.
Shelter for damp
- 3-season tent with full coverage rainfly + bathtub floor
- Footprint (forest floor stays wet for days)
- 4 extra stakes for guylines (wind off the coast)
- Tent gets pitched under tree cover when possible (less fly drumming, less fly soak)
Sleep system
- Synthetic-fill sleeping bag, 20°F rating (yes, even in summer — coastal Olympic nights drop to 45°F)
- Inflatable sleeping pad with R-value 4+ (cold ground draws heat all night)
- Compression dry bag for the sleeping bag
- Liner (silk or synthetic) — adds 10°F warmth and keeps the bag clean
The dry-bag discipline
Everything that absolutely cannot get wet — sleeping bag, dry clothes, electronics, paper map — goes in dry bags inside your pack. Pack covers help but don't seal; assume your pack will get wet through.
Footwear, two pairs
- Waterproof hiking boots for trail use
- Camp shoes (lightweight slip-ons) — wet boots will not dry overnight here. You don't want to put them on every time you step outside the tent.
Cook system
- Canister stove + windscreen + tarp for cooking in rain (cook under your vestibule or a separate pitched tarp)
- 2-liter pot
- Fire-starter that works wet (storm matches, lighter in waterproof case, ferro rod as backup)
Layers (the wet-cold puzzle)
The classic 3-layer system applies, but base layers should be merino wool or polyester — never cotton. Wet cotton stays wet and steals body heat. Merino stays warm even soaked.
Bug protection (June-July)
The PNW old-growth forests have manageable mosquitoes most of the year, but late June into July can be heavy in the Quinault and Hoh. Pack a head net and DEET 30%.
Pack like it's going to rain three days. If it doesn't, you've carried 2 pounds extra. If it does, you're warm and dry.
What you DON'T need
Sun protection beyond a hat brim. Cooling towels. Anything cotton. Down outerwear. Mid-weight gloves (you want light gloves you can squeeze water out of, not insulated ones).
