Washington's trail network is dominated by the Cascades and the Olympic Mountains — two distinct mountain ranges with different character, hazards, and seasons. PeakScout tracks conditions across the state's most iconic routes including Mount Rainier, the Enchantments, and the Olympic coast. Volcanic peaks above 10,000 ft retain snow into July, creating both opportunity (ski descents) and hazard (glacial crevasses, late-season avalanches). Wildfire smoke from surrounding states can degrade visibility significantly.

❓ Frequently Asked Questions
What is the best time to hike Mount Rainier?
July through September for most trails. The Muir Snowfield (Paradise) is skiable May–July. The Wonderland Trail (93 mi circumnavigation) requires 10–14 days. The iconicviews of sunrise alpenglow require permits (July–September, available at recreation.gov).
When is wildfire smoke worst in Washington?
July through September, especially during active fire seasons in the Cascades, British Columbia, and Oregon. AQI can shift to Unhealthy in hours. The marine layer typically clears morning fog but can trap smoke in the lowlands.
What makes Washington hiking unique?
Old-growth rainforests on the Olympic Peninsula (Hoh Rainforest gets 170 inches of rain per year), volcanic alpine zones above 10,000 ft, and the Cascade volcanic arc. Alpine glaciers are active — crevasses on Mt. Adams and Mt. Rainier require respect.
