Washington State is one of the best destinations for dog owners in the country — most state parks allow leashed dogs on trails, national forests are generally permissive, and the Pacific Northwest scenery is exceptional. This guide covers what to expect and how to plan a pet-inclusive trip.

Washington State Parks and Dogs

Washington state parks are among the most dog-friendly in the nation. Most parks allow leashed dogs on trails and in campgrounds. Some marine parks and sensitive habitat areas have restrictions. Dogs must be on a six-foot leash or less at all times.

National Forests in Washington

Olympic National Park Dog Rules

Mount Rainier National Park Dogs

Similar to Olympic — dogs are restricted to campgrounds, parking areas, and paved roads at Mount Rainier. No dogs on park trails. Consider surrounding national forest land where dogs are permitted on trails.

Ferry Travel With Pets in Washington
