From Rattlesnake Ledge to Hurricane Ridge — the top dog-friendly PNW trails, seasonal conditions, gear tips, and what a Seattle-born dog brand recommends.
The short answer: The Pacific Northwest offers some of the best dog-friendly hiking in North America — from old-growth rainforests on the Olympic Peninsula to alpine meadows in the North Cascades. The most dog-accessible trails include Hurricane Ridge (Olympic NP), Twin Falls (Olallie State Park), Franklin Falls, Rattlesnake Ledge, and the Carbon River Rainforest loop. For wet-climate hiking, a waterproof jacket rated 15,000 mmH₂O is essential gear — PNW trails deliver rain, mud, and sudden weather changes year-round.
PawTrk was built in Seattle, by someone who hikes with a dog. Every design decision in the Trail Series came from the specific reality of what outdoor life with a dog looks like in this region: sustained rain, muddy trails, cold mornings that warm into beautiful afternoons, and the kind of wet that soaks through a dog's coat before you're halfway to the summit.
This is a guide to the best dog-friendly trails in the PNW — written from the perspective of someone who's actually done them with a dog.
Before You Go: PNW Trail Rules
Most trails in Washington and Oregon allow leashed dogs. A few key rules to know:
- National Park trails: Dogs are generally restricted to paved roads, campgrounds, and some specific trails. Olympic and Mount Rainier have limited dog-friendly trail access — check the specific park's regulations before going.
- National Forest and State Park trails: Usually dog-friendly on-leash. This is where most of the best dog hiking in the PNW happens.
- Wilderness areas: Dogs allowed on-leash; some areas require pack-in pack-out waste management.
- Leash requirement: 6 feet maximum on nearly all managed trails in Washington State.
Always check current trail conditions at wta.org (Washington Trails Association) before heading out — trail closures, seasonal restrictions, and conditions change.
Best Dog-Friendly Hikes Near Seattle
Rattlesnake Ledge
Distance: 4 miles round trip | Elevation gain: 1,100 ft | Difficulty: Moderate
One of the most popular hikes near Seattle — and deservedly dog-friendly. The ledge at the top offers panoramic views over Rattlesnake Lake and the Cascades. The trail is wide, well-maintained, and busy on weekends. Expect other dogs.
What to know: Can be muddy in rain season (which is most of the year). A waterproof jacket keeps your dog clean and dry on the wet sections. Busy enough on weekends that reliable on-leash manners matter.
Trail conditions: WTA — Rattlesnake Ledge
Twin Falls — Olallie State Park
Distance: 2.6 miles round trip | Elevation gain: 500 ft | Difficulty: Easy–Moderate
Old-growth forest, two dramatic waterfalls, and a suspension bridge. One of the most beautiful short hikes near Seattle, and fully dog-friendly on leash. The forest canopy provides some rain cover, making it a good wet-weather option.
What to know: The trail follows the South Fork Snoqualmie River — dogs will find many opportunities to wade. Bring a towel. A waterproof jacket helps with the spray near the falls and the inevitable puddle encounters.
Trail conditions: WTA — Twin Falls
Franklin Falls
Distance: 2 miles round trip | Elevation gain: 400 ft | Difficulty: Easy
An easy walk through old-growth forest to one of Washington's most impressive roadside waterfalls — 70 feet of water dropping into a pool. Ideal for dogs of any fitness level and families with young children. Almost entirely shaded, which makes it cool even in summer.
What to know: Very popular, especially in summer. The mist from the falls reaches the viewing area — dogs (and people) get wet. A waterproof jacket is worth having for the last quarter mile.
Poo Poo Point — Chirico Trail
Distance: 3.8 miles round trip | Elevation gain: 1,600 ft | Difficulty: Moderate–Strenuous
A steep but rewarding climb to a paragliding launch site with sweeping views of the Issaquah Alps. Popular with dogs and their owners. The summit is open and exposed — great on clear days, cold and windy when weather rolls in.
What to know: Exposed at the top means real wind and weather exposure. This is a trail where having a waterproof jacket on your dog earns its keep — summit temperatures and conditions can differ significantly from the trailhead.
Best Dog-Friendly Hikes on the Olympic Peninsula
Hurricane Ridge — Hurricane Hill Trail
Distance: 3.2 miles round trip | Elevation gain: 700 ft | Difficulty: Moderate
One of the few Olympic National Park trails that allows dogs. Hurricane Hill offers subalpine meadows, wildflowers in summer, and views across the Strait of Juan de Fuca to Vancouver Island. Weather changes fast at elevation — clear mornings can turn to wind and rain quickly.
What to know: Dogs must be on a 6-foot leash at all times. Check Olympic NP's current dog policy before visiting. The road to Hurricane Ridge can close in winter — check conditions at nps.gov/olym. This is a trail where weather protection for your dog is genuinely important: elevation, exposure, and classic PNW unpredictability.
Hoh Rain Forest Loop Trails
Distance: 0.8–17 miles (multiple options) | Difficulty: Easy to Strenuous
The Hoh Rain Forest is one of the few temperate rainforests in the world — moss-draped maples, towering Sitka spruce, and the kind of green that doesn't exist anywhere else. The Hall of Mosses and Hoh River Trail are partially dog-accessible (check current NPS regulations).
What to know: This is a rainforest — it rains here a lot, and the trails are often wet and muddy. A dog without a waterproof jacket will be comprehensively soaked within the first mile. Bring gear accordingly.
Best Dog-Friendly Hikes in the North Cascades
Chain Lakes Loop — Mount Baker
Distance: 6.5 miles | Elevation gain: 1,300 ft | Difficulty: Moderate
One of the most spectacular alpine loops in Washington — subalpine lakes, views of Mount Baker and Mount Shuksan, and open terrain that dogs love. Dogs are allowed on-leash throughout.
What to know: This trail is only accessible in summer (typically July–October) due to snow. Weather at elevation near Mount Baker is famously unpredictable — bring rain gear for yourself and your dog even on clear-sky mornings. One of the trails where the Trail Series jacket most clearly earns its keep.
Lake Serene — Index
Distance: 8 miles round trip | Elevation gain: 2,500 ft | Difficulty: Strenuous
A challenging but rewarding hike to a stunning glacially-carved lake below Mount Index. The upper sections involve some boulder scrambling — this is a trail for conditioned dogs. Stunning views at the top.
What to know: The approach involves multiple stream crossings and can be muddy early season. Dogs will get wet — a waterproof jacket reduces how soaked they get on the approach and helps them stay warm at the cold, exposed lake.
Gear for PNW Dog Hiking
The one non-negotiable: A waterproof jacket. PNW trails deliver rain in every month of the year, and many of the best hikes involve exposure, elevation, and the kind of sustained wet that soaks a dog's coat completely within 30 minutes.
The PawTrk Trail Series Jacket — rated 15,000 mmH₂O waterproof and 30,000 g/m²/24h breathable — was designed specifically for this environment. Full chest and belly coverage handles trail conditions that back-only jackets miss. High breathability means dogs can hike hard without overheating even with a jacket on.
Also bring: Water (8 oz per hour of hiking), a collapsible bowl, a towel for post-hike paw cleaning, and a basic first aid kit.
Seasonal Trail Guide
| Season | Conditions | What to Pack |
|---|---|---|
| Spring (Mar–May) | Mud, rain, snow at elevation | Waterproof jacket essential, booties useful |
| Summer (Jun–Aug) | Best conditions, crowds, afternoon storms | Jacket for summit hikes, extra water |
| Fall (Sep–Nov) | Rain returns, fall colors, fewer crowds | Waterproof jacket essential |
| Winter (Dec–Feb) | Snow at elevation, rain everywhere else | Jacket required, check trail access |
Frequently Asked Questions
Are dogs allowed in Washington State Parks? Yes — most Washington State Parks allow dogs on-leash (6 feet maximum). Some areas within parks may have restrictions. Check the specific park's rules at parks.wa.gov before visiting.
Are dogs allowed in Olympic National Park? Dogs have limited access in Olympic NP — they're generally permitted in campgrounds, on paved roads, and on a small number of specific trails (including Hurricane Ridge Road and Hurricane Hill Trail). They're not permitted on most backcountry trails. Check current regulations at nps.gov/olym.
What's the best season to hike with a dog in the PNW? Late summer (July–September) offers the best trail access, most stable weather, and the most open high-elevation routes. That said, PNW hiking is a year-round activity — the key is having the right gear. A waterproof jacket makes spring, fall, and winter hiking fully enjoyable rather than an endurance test.
Do I need to bring water for my dog on PNW trails? Yes — even in a region full of streams and rivers, don't let your dog drink from trail water sources without filtering. Giardia is common in backcountry water throughout the PNW. Bring at least 8 oz of water per hour of hiking.
What should I do if my dog gets muddy on the trail? Rinse paws and legs at the trailhead if there's a water source nearby. A waterproof jacket dramatically reduces how muddy a dog gets — the jacket takes the mud, not the coat, and wipes clean easily. Check paws for thorns and cuts before loading into the car.
Are PNW trails dog-friendly year-round? Many lower-elevation trails (Rattlesnake Ledge, Twin Falls, Franklin Falls) are accessible year-round. Higher-elevation trails (Chain Lakes, Lake Serene) are snow-covered from October through June or July. Check wta.org for current conditions before any hike.
The Bottom Line
The Pacific Northwest has some of the best dog-hiking terrain in the country — and the weather to go with it. Preparation makes the difference between a miserable wet slog and an adventure you both remember well.
A quality waterproof jacket built for PNW conditions, enough water, and a trail matched to your dog's fitness level covers most of it.
