To help hikers find their way in the Norwegian mountains and forests, and to ensure they choose the hike that is best suited to their ability, Norway uses a shared standard for grading all its marked paths. The trails are all colour-coded to let hikers know what to expect.
Norway’s grading system is based on four difficulty levels used both nationally and internationally: green, blue, red and black. The trail grading colours (and the difficulty levels they correspond to) are as follow:
Green - Easy
- No special skills required.
- Mainly short walks.
- Special symbols mark the areas suitable for wheelchair users/prams.
Elevation gain and length
- < 300 m
- < 5 km
Type of path
- Tarmac, gravel, forest roads and good paths.
- Work done on paths to enable easy walking.
- Firm, even and obstruction-free path.
- No streams to be crossed.
Degree of elevation/ exposure
- Moderate ascents, but no steep or difficult sections.
