Start by using reputable trail databases such as AllTrails, Washington Trails Association (WTA), and local parks department sites. Filter trails by distance, elevation gain, rating, and difficulty (easy, moderate, hard). Read recent trip reports to check for current trail conditions, closures, and seasonal challenges like snow or mud. Compare elevation gain with distance to understand how steep a trail will feel, and pay attention to user photos and maps to verify that the terrain matches your comfort level. When in doubt, begin with shorter, lower-elevation hikes closer to the city and gradually work up to more challenging routes as your fitness and confidence improve.

Several trails near Seattle are well-suited for beginners and casual hikers. Popular options include Discovery Park Loop in Seattle for coastal views and mild elevation, Rattlesnake Ledge near North Bend for a shorter but moderately steep trail with a rewarding viewpoint, and Twin Falls near I-90 for forest scenery and waterfalls. For a more relaxed experience, consider Seward Park’s perimeter loop along Lake Washington or Cougar Mountain’s easier routes like the Wildside or Red Town trails. Always confirm current conditions and parking information before you go, especially on weekends when these destinations can be busy.

Washington Trails Association (WTA) is one of the most reliable resources, offering up-to-date trip reports from local hikers, details on trail work, and notices about closures. AllTrails provides user reviews, GPS tracks, and recent photos that help you assess current conditions. Check official land manager sites such as Washington State Parks, the U.S. Forest Service (Mt. Baker-Snoqualmie National Forest), and King County or Seattle Parks for authoritative information on closures, permits, and parking requirements. During winter and spring, review avalanche forecasts from the Northwest Avalanche Center and road conditions from the Washington State Department of Transportation when heading into the Cascades via I-90 or Highway 2.

Many popular trailheads near Seattle require a parking pass or permit rather than a separate hiking permit. For hikes in Washington State Parks, including some areas around the Puget Sound, you typically need a Discover Pass. For U.S. Forest Service trailheads such as those along the I-90 corridor and in the Mt. Baker-Snoqualmie National Forest, a Northwest Forest Pass or equivalent federal recreation pass is often required. Some high-demand areas or overnight trips may require additional permits or reservations. Always confirm which pass applies to your chosen trailhead and purchase it in advance or at designated vendors to avoid fines and ensure compliance with local regulations.

Weather in the Seattle area and the nearby Cascades can change quickly, so check the forecast and pack layers, a waterproof shell, and extra warm clothing, even in summer. Carry the ten essentials, including a map, navigation tools, headlamp, first-aid kit, extra food and water, and a fully charged phone with offline maps. Start hikes early to avoid being caught out after dark and let someone know your route and expected return time. Trail surfaces can be wet, muddy, or icy, so wear sturdy footwear with good traction and consider microspikes in shoulder seasons. Practice Leave No Trace principles, be aware of wildlife, stay on established trails to avoid getting lost or causing erosion, and respect any posted closures or warnings.
