Distance is one measure of a hike. Elevation gain is the one that decides how your legs feel the next morning. We pulled every trail in Washington with a measurable elevation-gain tag — out of the 23,332 entries OutsideAtlas tracks here — and ranked them by total vertical. The result is a roster of climbs that punch above their mileage.
Washington compresses Olympic rainforest, Cascade volcanoes (Rainier, Baker, Glacier Peak, Adams, St. Helens), the high desert east of the divide, and an island-strewn coast into one state. Mount Rainier (14,411 ft, Camp Muir at 10,000 ft), Mount Baker, and the Olympic high country deliver Washington's biggest vertical objectives. Hypothermia and rapidly changing weather on Cascade summits, river crossings on Wonderland and PCT, and wildfire smoke in late summer.
Our rankings here are data-driven — pulled from the 23,332 mapped entries OutsideAtlas tracks in Washington — but the data has limits worth being honest about. Elevation-gain figures depend on the surveyor and the digital-elevation model used. Some trails are missing this tag entirely and are excluded from the list. Treat numbers as approximate but directionally reliable.

#1. Upper Gray Wolf River Trail
Upper Gray Wolf River Trail leads the elevation rankings with 4,150 ft of climbing — the kind of gain that turns a 6-mile day into an honest workout. Expect 4,150 ft of gain on a forgiving grade. Local trail-association reports tend to agree this is one of the better-maintained options in the area, which matters more on a hike of this length than on a quick walk. Climbing fitness — not raw mileage — is the gating factor. Trekking poles and an early start pay off.

A few pieces of context are worth keeping in mind specifically for Washington. Mid-July through September for high Cascades; year-round in the Olympics (with weather caveats); high desert spring and fall. Hypothermia and rapidly changing weather on Cascade summits, river crossings on Wonderland and PCT, and wildfire smoke in late summer.
Always cross-reference the official land-manager page before driving out — closures, fire restrictions, and seasonal road access can change quickly. Our trail pages link directly back to the OpenStreetMap source so you can see the tags we're working from.
If you're new to hiking generally, our beginner's guide covers footwear, layering, and the day-pack basics. For safety planning on bigger objectives, the ten essentials guide is worth twenty minutes of reading.
