The good news: the Okanogan-Wenatchee, Colville, and Gifford Pinchot national forests are all dog-friendly with extensive dispersed camping. The bad news: the most-photographed spots — Enchantments, Olympic coast, Mt. Rainier trails — either ban dogs or require permits that book out in February. Plan around the crowds and you'll find Washington's dog camping is genuinely exceptional.
Best Regions for Dogs
Okanogan-Wenatchee NF — Methow Valley
Eastern Washington's dry side of the Cascades. The Methow Valley gets 300 days of sunshine compared to Seattle's gray winters. The Chewuch River and Twisp River drainages both offer water access for dogs. Less crowded than any comparable terrain west of the crest.
Colville National Forest — Sullivan Lake Area
Northeast Washington near the Canadian border — pine forest, lake swimming, and virtually no one in the campgrounds on weekdays. Sullivan Lake allows dogs and has a gradual beach entry for swimming. Grizzly bears are present in the Selkirks — hang your food.
Gifford Pinchot NF — Lewis River Corridor
South Cascades near Mt. St. Helens. The Lewis River has multiple waterfalls and swimming holes that dogs love. Old growth forest keeps temperatures cool even in summer. Dogs allowed on most trails — check individual trailhead signs.
Washington Dog Camping Tips
Cascades permits
Many Cascades trailheads require a Northwest Forest Pass ($30/year or $5/day). Dogs are banned from Enchantments core zone, most of Olympic NP backcountry, and several Mt. Rainier trails. Always check recreation.gov and the specific ranger district before planning a hike-in site.
Bear country
The Cascades and northeast Washington have both black bears and, in the Selkirks, grizzlies. Use bear canisters or bear boxes. Keep your dog from investigating any wildlife — a dog that charges a bear is a dog in serious trouble. Many Washington campgrounds have food storage lockers — use them.
