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 Iowa with a measurable elevation-gain tag — out of the 3,511 entries OutsideAtlas tracks here — and ranked them by total vertical. The result is a roster of climbs that punch above their mileage.
Iowa is mostly tallgrass prairie and corn — but the Loess Hills in the west and the driftless area in the northeast contain unexpectedly rugged terrain. Hawkeye Point (1,670 ft) is the high; vertical-gain rankings flag the Loess Hills and Effigy Mounds NM terrain. Ticks are abundant; in the Loess Hills, summer rattlesnake encounters happen.
Our rankings here are data-driven — pulled from the 3,511 mapped entries OutsideAtlas tracks in Iowa — 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. 101x
101x ranks #1 for vertical gain, sitting near North Liberty in Johnson 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.

A few pieces of context are worth keeping in mind specifically for Iowa. Spring wildflowers and fall colors are ideal; summer is hot and humid; winter brings serious wind chill on prairie trails. Ticks are abundant; in the Loess Hills, summer rattlesnake encounters happen.
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.
