Understanding your rating

How the difficulty score works

How difficulty is calculated

Each input you provide is converted into points on a shared scale: distance, elevation gain, terrain, and trail surface each add points as they increase, while your experience level and backpack weight shift the score up or down.

The points are added together into a single score, which is then mapped onto a 0–100 scale and matched to one of five difficulty levels, from Easy to Very Difficult.

Elevation and difficulty

Elevation gain is one of the strongest drivers of difficulty. A short trail with a steep, sustained climb can easily outscore a much longer, flatter route.

  • Under roughly 150 m of gain contributes very little to the score.
  • Gains above 800–1,200 m push the score sharply higher, regardless of distance.
  • Elevation is combined with terrain, since climbs on loose or rocky ground are harder than climbs on a smooth path.

Terrain and difficulty

Terrain and trail surface are scored separately because they capture different things: terrain reflects the overall shape of the route, while surface reflects what’s underfoot.

  • Flat / Rolling terrain with a Paved / Gravel surface scores lowest.
  • Steep / Mountainous or Alpine / Exposed terrain adds significant points, especially in combination with rocky or loose surfaces.
  • Technical, loose, or scree-covered surfaces raise difficulty even on otherwise moderate terrain.

Tips for beginners

If you’re newer to hiking, use the score as a guide for how conservative to be with your plan.

  • Start with trails that land in the Easy to Moderate range while you build experience.
  • Treat a Challenging or higher rating as a sign to bring a more experienced hiking partner.
  • Keep your pack as light as reasonably possible — pack weight has an outsized effect on beginner difficulty.
  • Re-run the calculator with a lower experience setting if you’re unsure, to see a more cautious estimate.

Difficulty ratings are estimates, and trails can vary significantly even within the same category. Weather, trail maintenance, exposure, water crossings, and route-finding can all make a trail harder or easier than its score suggests. Always check current trail reports before you go.

FAQ

Frequently asked questions

How is the difficulty score calculated?

Distance, elevation gain, terrain, and trail surface each contribute points as they increase. Your experience level and backpack weight then adjust the total, which is mapped to a 0–100 scale and a difficulty label.

Why does experience level change the difficulty score?

The same trail feels different depending on who’s hiking it. Selecting “Beginner” raises the effective score, while “Advanced” lowers it, reflecting how conditioning and trail experience change perceived difficulty.

What’s the difference between “Terrain” and “Trail Surface”?

Terrain describes the overall shape of the route — flat, hilly, steep, or alpine. Trail surface describes what’s actually underfoot, from paved paths to loose scree, and the two are scored separately.

Does backpack weight really affect difficulty this much?

Yes. A heavy multi-day pack adds meaningful strain, especially on climbs and technical terrain, so it’s weighted more heavily than a light day pack in the score.

What does a “Challenging” rating actually mean on the trail?

It sits in the middle of the scale — typically noticeable elevation gain or a longer distance combined with mixed terrain. Most fit, moderately experienced hikers can complete it with reasonable preparation.

Can two trails with the same score feel very different?

Yes. The score reflects the factors you enter, but things like weather, exposure, water crossings, and how well a trail is marked aren’t captured, and can make two similarly scored trails feel quite different.

Should beginners avoid “Very Difficult” trails entirely?

It’s generally wise to build experience gradually rather than starting there. If a trail scores Very Difficult, consider it a strong signal to gain more experience first or hike with an experienced partner.

How often should I recalculate difficulty for a trip?

Recalculate any time a key input changes — a route change, a heavier pack, or a shift in who’s joining the hike can meaningfully change the estimate.
