What Is Elevation Gain?
Read cumulative ascent, net height change and an elevation profile before choosing a hike.
Elevation gain is the total uphill climbing on a route. Add each uphill section, including climbs after a descent. It is different from the height of the summit and from the difference between your starting and finishing elevations.
This is why a hike that returns to the car can have substantial elevation gain even though its net height change is zero. For planning, read distance and gain together. The NPS difficulty guide also advises looking beyond the difficulty label at the underlying measurements.
Read the profile one climb at a time
Here is an original teaching example, not a recorded trail. The successive elevations are 1,000 m, 1,200 m, 1,100 m and 1,400 m. Follow the uphill sections in the diagram on this page; the dip matters.
| Section | Change | Added to elevation gain |
|---|---|---|
| Start to first high point | Climb 200 m (660 ft) | 200 m (660 ft) |
| First high point to dip | Descend 100 m (330 ft) | Nothing |
| Dip to finish | Climb 300 m (980 ft) | 300 m (980 ft) |
| Entire route | Finish 400 m (1,310 ft) above start | 500 m (1,640 ft) |
The calculation is 200 + 300 = 500 m. Subtracting the start from the finish gives only 400 m. That subtraction misses the climbing needed to regain the height lost at the dip.
Four numbers that answer different questions
Elevation gain describes accumulated uphill work. Elevation loss adds the downhill sections. Maximum elevation identifies the highest point reached. Starting elevation tells you where the day begins. None substitutes for the others.
A mountain road may take you to a high trailhead before you walk. That raises the starting elevation without adding walking gain. Conversely, a low-level route can involve repeated climbs. Do not count a car's climb as part of the hiking figure.
An elevation profile shows how climbing is distributed along distance. A gradual rise and a concentrated climb can have the same gain. Look for long descents too: reaching the highest point does not finish an out-and-back day.
Why two route listings may disagree
Check that both sources describe the same start, finish, direction and optional detours. One may quote a one-way section while the other covers the complete return. Recorded tracks and maps may also use different sampling and smoothing. More decimal places do not automatically mean a more useful figure.
When values disagree, keep the source and uncertainty visible. Ask the route provider which track the number refers to. Avoid averaging two unmatched routes into a number that neither source actually supports.
Turn the number into a planning decision
Use a recent walk you understand as a comparison, then consider terrain, weather, pack and access. Gain alone cannot predict your duration or judge whether a route fits everyone in a group.
For a day with driving, write separate rows for the road and the walk. Record full walking distance, cumulative ascent, highest elevation and the source date. If ascent is missing, write “Not confirmed” and ask for the exact track; do not enter zero.

Elevation gain is all the uphill climbing on a route. It is not just the difference between the start and finish. Imagine starting at one thousand meters. You climb two hundred meters, descend one hundred, then climb three hundred. Your total uphill gain is five hundred meters. You finish only four hundred meters above the start, because the descent reduced the net change. A loop can finish at its starting height and still contain a lot of climbing. Read full walking distance and gain together, then look at terrain, descents and conditions. This is a teaching example, not a recorded trail. If a real route's ascent is missing, mark it not confirmed and ask which exact track the figure describes.
