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 Indiana with a measurable elevation-gain tag — out of the 4,447 entries OutsideAtlas tracks here — and ranked them by total vertical. The result is a roster of climbs that punch above their mileage.
Indiana's southern hills (Hoosier National Forest, Brown County) offer surprisingly steep terrain; the north is mostly flat farmland and Lake Michigan dunes. Hoosier Hill (1,257 ft) is the state high; vertical-gain rankings here flag southern-hills routes like Hemlock Cliffs and Pate Hollow. Copperheads and timber rattlesnakes in southern hills; ticks and mosquitoes statewide.
Our rankings here are data-driven — pulled from the 4,447 mapped entries OutsideAtlas tracks in Indiana — 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. Dunes Long Trail Alternates
Dunes Long Trail Alternates ranks #1 for vertical gain, sitting near Chesterton in Porter 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 Indiana. Spring and fall are prime; summer humidity is significant; winter trails are quiet but ice-prone in ravines. Copperheads and timber rattlesnakes in southern hills; ticks and mosquitoes statewide.
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.
