Difficulty Grading

All of these hikes would be regarded as easy for the hiking fit. This grading system is intended for regular hikers who are comfortable hiking for 3–4 hours but are not necessarily very fit.

The grading system is inspired by the Shenandoah Hiking Difficulty Equation, with additional adjustments for steepness, distance interaction, and terrain difficulty.

Hiking Difficulty Calculator

[+] How this calculator works

This calculator estimates hiking difficulty using distance, elevation gain and terrain type.

Non-linear Scaling

  • The calculator adjusts the effort based on elevation relative to distance using a non-linear ratio.
  • Elevation gain contributes more strongly to the final score than distance, reflecting the greater physical effort of sustained climbing.
  • This means that short steep climbs are more heavily weighted than long gradual ones.
  • The terrain factor modifies the score relative to a standard uneven rocky trail.
  • Firm Path / Track (~0.93) – flat sandy paths, jeep tracks, hard-packed soil
  • Uneven Rocky Trail (1.00) – typical mountain trail with rocks, steps, roots
  • Rough Trail / Light Scrambling (~1.12) – unstable footing, occasional hand use
  • Scrambling / Off-Trail (~1.20) – frequent hand use, boulder hopping, route finding

Difficulty Grades

  • 1–4 Easy
  • 5–6 Moderate
