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 Maine with a measurable elevation-gain tag — out of the 9,553 entries OutsideAtlas tracks here — and ranked them by total vertical. The result is a roster of climbs that punch above their mileage.
Maine's coast is famously rocky and indented; the interior holds the Mahoosucs, the Bigelow Range, and Mount Katahdin — the northern terminus of the Appalachian Trail. Katahdin via the Knife Edge gains 4,200 ft in 5 miles — one of the country's most exposed and committing day hikes. Hypothermia in shoulder seasons, blowdown after windstorms, and rapidly changing weather on Katahdin's exposed Tablelands.
Our rankings here are data-driven — pulled from the 9,553 mapped entries OutsideAtlas tracks in Maine — 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. International Appalachian Trail New-Brunswick
International Appalachian Trail New-Brunswick ranks #1 for vertical gain, sitting near Limestone in Aroostook County. Tagged hard in OpenStreetMap. 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.

Sawyer Mountain Summit Trail ranks #2 for vertical gain, sitting near Cornish in York County. Expect ground surface on a genuinely demanding grade.

A few pieces of context are worth keeping in mind specifically for Maine. Mid-June through early October — black flies in June, prime weather in late July and August, foliage in early October. Hypothermia in shoulder seasons, blowdown after windstorms, and rapidly changing weather on Katahdin's exposed Tablelands.
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.
