Trail Difficulty Rating System

General Information
Trail Solutions

The IMBA Trail Difficulty Rating System is a basic method used to categorize the relative technical difficulty of recreation trails. The IMBA Trail Difficulty Rating System can:

  • Help trail users make informed decisions
  • Encourage visitors to use trails that match their skill level
  • Manage risk and minimize injuries
  • Improve the outdoor experience for a wide variety of visitors
  • Aid in the planning of trails and trail systems

This system was adapted from the International Trail Marking System used at ski areas throughout the world. Many trail networks use this type of system, most notably resort-based mountain biking trail networks. The system applies to mountain bikers best, but also is applicable to other visitors such as hikers and equestrians.
