CHOOSING A ROUTE

Read the colour. Then the ground.

Grades describe a venue’s intended progression, not a nationwide guarantee. Weather, speed, exposure and fatigue can transform the same trail.

Green · easy

Usually wide, low-gradient and relatively smooth. Suitable for novice riders with basic braking and steering, but not automatically traffic-free or hazard-free.

Blue · moderate

Narrower trails with moderate gradients, small obstacles, berms and uneven surfaces. Riders should control speed and ride standing over rough ground.

Red · difficult

Steeper, faster and more technical, with roots, rocks, drops and unavoidable features. Requires confident braking, line choice, fitness and trail experience.

Black · severe

Large or committing features, steep technical terrain and serious consequences. Intended for highly experienced riders using appropriate equipment.

Other labels

Orange, downhill, freeride, pro-line and double-black systems are operator-specific and may include mandatory jumps or drops. Natural or “ungraded” does not mean easy: navigation, remoteness and changing ground conditions add risk.

Should I ride it?

  • Read the operator’s current description and inspect trailhead signs.
  • Start one level below your limit at an unfamiliar venue.
  • Ask whether features have ride-around lines and whether climbing fitness is required.
  • Turn back or walk a section if conditions or confidence change.
