Key takeaways
- Elevation gain is the total uphill a route climbs, in feet or meters.
- Cumulative gain adds up every climb, so rolling trails have more gain than net elevation suggests.
- Along with distance, it's the key measure of a hike's difficulty.
- Climbing demands far more effort than flat distance, so high gain means a hard hike.
What elevation gain is
Elevation gain is the total amount of uphill climbing on a route, measured in feet or meters. The important version is cumulative elevation gain, which adds up every climb along the way — not just the difference between the start and the high point. So a rolling trail that goes up and down repeatedly can have far more gain than its net elevation change suggests.
Why it matters more than distance
Climbing uphill takes far more effort, time, and energy than flat ground. Two trails of equal length can differ enormously: a flat 8-miler is easy, while an 8-miler with 3,500 feet of gain is a serious workout. That’s why elevation gain, alongside distance, is the key metric for a hike’s difficulty.
Comparing two 10-mile hikes, a hiker checks elevation gain: one has 1,000 feet (an easy day), the other 4,000 feet (a grueling climb). Same distance, very different effort — so they plan extra time and food for the high-gain route.
How to find it
Guidebooks, apps, and maps list a route’s cumulative elevation gain; you can also add up the climbs from contour lines on a topographic map or read it from a GPS track. It’s the same concept trail runners call vert, and a major input to a trail rating.
The bottom line
Elevation gain — the total uphill a route climbs — is, alongside distance, the truest measure of a hike's difficulty, because climbing costs far more effort than flat miles. Use cumulative gain (which counts every up) rather than net change, since rolling trails add up. A flat hike and a high-gain hike of equal length are worlds apart in effort.
Frequently asked questions
What is elevation gain?
Elevation gain is the total amount of uphill a route climbs, measured in feet or meters. 'Cumulative' elevation gain adds up all the climbing across the whole route — every up — not just the difference between the lowest and highest points. So a trail that rolls up and down repeatedly can have much more elevation gain than its net change in elevation would suggest.
Why does elevation gain matter more than distance alone?
Because climbing uphill takes far more effort, time, and energy than covering flat ground. Two trails of the same length can be vastly different in difficulty: a flat 8-miler is easy, while an 8-miler with 3,500 feet of gain is a serious workout. That's why elevation gain, alongside distance, is the key metric for gauging a hike's difficulty and planning your time and effort.
How do you find a route's elevation gain?
Guidebooks, trail apps, and maps usually list a route's total (cumulative) elevation gain. You can also estimate it from a topographic map by adding up the climbs along the route using the contour lines, or read it from a GPS track. Pay attention to whether a figure is net or cumulative gain — cumulative is more telling for difficulty on rolling terrain.
